How To Make Aluminium Windows And Doors

Aluminum is a non-ferrous metal (which means it will not draw a magnet) that is lightweight. There are several different grades of scrap aluminum, and all of them vary in price. At most scrapyards, aluminum is broken down into the following grades:

Cast Aluminum

Radiators (clean and contaminated)

Extrusions (clean and contaminated)

Wheels (Clean and Chrome Plated)

Siding

Aluminum/Copper Radiators (clean and contaminated)

Old Sheet

Cast aluminum is very brittle and when broken, the inside will appear very grainy. A majority of the cast aluminum that comes across our scale is from auto parts. Transmission housings, engine cylinder heads, and electronic covers are all examples of cast aluminum auto parts. Other miscellaneous items that are made of cast aluminum include BBQ covers, some hot plates and skillets, and some light housings.

Aluminum radiators can be brought to our yard in two forms, contaminated or clean. A clean aluminum radiator must have all tanks, hoses, and steel and plastic removed. The plastic tanks on each end of the radiator will typically contain steel, sometimes however they will contain a tube made of aluminum or brass.

Extrusion is the process of pushing material through a die to give it a particular shape, very much like a Play-Doh spaghetti machine. The most common form of aluminum extrusion we see is window frames, but it is used very often in other framing systems and structural applications. Extrusions are broken down into contaminated and clean grades, with clean extrusion containing no steel, plastic, rubber, or insulation.

Aluminum Wheels come in two varieties, aluminum and chrome plated aluminum. Chrome plated wheels are worth a little less than pure aluminum due to the chrome contamination. Wheels with plastic face covers are also considered chrome plated due to the contamination of plastic and glue. Our listed wheel price assumes wheel weights, valve stems, and center caps are still attached. If these have been removed from your wheels discuss it with our scale operator and he may be able to increase your price.

Aluminum siding also includes gutters, downspouts, and other flat stock aluminum items. To receive the aluminum siding price, the material must not contain steel, Styrofoam, tar, insulation or any other contamination.

Aluminum/copper radiators are found in air conditioning units. They are copper tubes surrounded by aluminum fins. A clean aluminum/copper radiator will contain no steel flanges. If the steel flanges are cut off of a dirty aluminum/copper radiator, the rest of the radiator can be sold as clean and the flanges can be sold as aluminum breakage if they still contain some aluminum and copper.

Old sheet is the lowest grade of scrap aluminum and just about everything that has not been mentioned so far falls into this category. Some common aluminum sheet items include pots and pans, pop cans, lawn chairs, and screens. Siding containing excessive Styrofoam or tar will also be bought as aluminum sheet.

In general metals like steel and aluminum is put to use in several industries, right from automobile, to telecommunication, transport, utensil manufacturing and at times even in the toy industry. Thus, both of these metals are in huge demand and find place is almost all the major manufacturing industries in the world.

Just after steel, aluminum is the other metal which is hugely popular all over the world. This can put in a manner stating that aluminum is the second most popular metal in the globe after steel. The former is widely available, has impressive properties, and is affordable, light weight, can withstand high temperatures and so on. And above all the aluminum extrusion involved in getting different shapes and forms for suppliers is cost-effective and simple. Both in US and Europe building industry and the telecom as well is highly dependent on aluminum extruded products. These products find a number of usages and are used in many applications.

So, what is aluminum extrusion? This is a process through which aluminum is given certain shapes and forms. It starts with the hot cylindrical billet of aluminum which is pushed through a shaped die. The billet is cut from DC cast log and placed in heated container (450°C - 500°C). When pushed through the die the metal flows through the steel die. The die is placed at the other end of the container. Now, once the log passes it produces a section, this can be cut into shapes either in long length or short. The section is cuts according to the customized demands of the clients since the log is meant to be used for any particular industry. In certain extrusion process rectangular shaped billets. In this process only wide section sized extrusions are produced. This again depends according the demands of the supplier.

Aluminum extrusion is done for several kinds of industry and these aluminum extruded products are very commonly used in building industry. In this industry you can use aluminum in prefabricated houses/building structures, window and door frame systems, curtain walling, roofing and exterior cladding, and shop fronts. Besides, they also find place in the telecommunication and transport industry. In transport industry aluminum extruded products are found in rail vehicles, marine applications, airframes and for vehicles on the road.

So, what makes aluminum so popular? It is the versatility and the flexibility of the material that turns in so popular. Since aluminum is high temperature resistance and is corrosion resistant as well it is used to make utensils and is also used on transport vehicles. Besides, it is strong even though it is light weight and thus it is used in airframes.

So, if you are out there still deciding on selecting aluminum extruded products or some other metal you can give your votes to this metal as it is affordable and durable as well. No more second thoughts to this go ahead with aluminum extrusion and the products.

Aluminum Extrusion Framing

High strength aluminium alloys.

The origin of aluminium alloys in aircraft construction started with the first practical all-metal aircraft in 1915 made by Junkers in Germany, of materials said to be `iron and steel'. Steel presented the advantages of a high modulus of elasticity, high proof stress and high tensile strength. Unfortunately these were accompanied by a high specific gravity, almost three times that of the aluminium alloys and about ten times that of plywood. Aircraft designers during the 1930s were therefore forced to use steel in its thinnest forms. To ensure stability against buckling of the thin plate, intricate shapes for spar sections were devised.

In 1909 Alfred Wilm, in Germany, accidentally discovered that an aluminium alloy containing 3.5 per cent copper, 0.5 per cent magnesium and silicon and iron, as unintended impurities, spontaneously hardened after quenching from about 480°C. The patent rights of this material were acquired by Durener Metallwerke who marketed the alloy under the name Duralumin. For half a century this alloy has been used in the wrought heat-treated, naturally aged condition. The improvements in these properties produced by artificial ageing at a raised temperature of, for example, 175°C, were not exploited in the aircraft industry until about 1934.

In addition to the development of duralumin (first used as a main structural material by Junkers in 1917) three other causes contributed to the replacement of steel by aluminium alloys. These were a better understanding of the process of heat treatment, the introduction of extrusions in a wide range of sections and the use of pure aluminium cladding to provide greater resistance to corrosion. By 1938, three groups of aluminium alloys dominated the field of aircraft construction and, in fact, they retain their importance to the present day. The groups are separated by virtue of their chemical composition, to which they owe their capacity for strengthening under heat treatment.

The first group is contained under the general name duralumin having a typical composition of: 4 per cent copper, 0.5 per cent magnesium, 0.5 per cent manganese, 0.3 per cent silicon, 0.2 per cent iron, with the remainder aluminium. The naturally aged version was covered by Air Ministry Specification DTD 18 issued in 1924, while artificially aged duralumin came under Specification DTD 111 in 1929. DTD 111 provided for slight reductions in 0.1 per cent proof stress and tensile strength.

The second group of aluminium alloys differs from duralumin chiefly by the introduction of 1 to 2 per cent of nickel, a high content of magnesium and possible variations in the amounts of copper, silicon and iron. `Y' alloy, the oldest member of the group, has a typical composition of. 4 per cent copper, 2 per cent nickel, 1.5 cent magnesium, the remainder being aluminium and was covered by Specification DTD 58A issued in 1927. Its most important property was its retention of strength at high temperatures, which meant that it was a particularly suitable material for aero engine pistons. Its use in airframe construction has been of a limited nature only. Research by Rolls-Royce and development by High Duty Alloys Ltd produced the `RR' series of alloys. Based on Y alloy, the RR alloys had some of the nickel replaced by iron and the copper reduced. One of the earliest of these alloys, RR56 had approximately half of the 2 per cent nickel replaced by iron, the copper content reduced from 4 to 2 per cent, and was used for forgings and extrusions in aero engines and airframes.

The third and latest group depends upon the inclusion of zinc and magnesium and their high strength. Covered by Specification DTD 363 issued in 1937, these alloys had a nominal composition: 2.5 per cent copper, 5 per cent zinc, 3 per cent magnesium and up to 1 per cent nickel. In modern versions of this alloy nickel has been eliminated and provision made for the addition of chromium and further amounts of manganese.

Aircraft structural aluminium.

Of the three basic structural materials, namely wood, steel and aluminium alloy, only wood is no longer of significance except in laminates for non-structural bulkheads, floorings and furnishings. Most modern aircraft still rely on modified forms of the high strength aerospace aluminium alloys which were introduced during the early part of the 20th century. Steels are used where high strength, high stiffness and wear resistance are required. Other materials, such as titanium and fibre-reinforced composites first used about 1950, are finding expanding uses in airframe construction.

How To Make Aluminium Windows And Doors

Aluminum sliding doors are located in various rooms of a building. This could be used as terrace or patio doors leading into the garden. Other places could be on first floor leading into the balcony from a family room upstairs or bedroom. The are different types used, one side fixed and other sliding and or two sliding panels and a fixed one. The room and size of opening determines which type to use. This also determines the glazing to be put.

When ready to fix an aluminum sliding door, whether due to replacement or anew, first measure the opening. Ensure that all railings , rollers, glazing are all in place. Line the opening smooth with plaster and check sides, floor and top. Ensure corners are square, jambs are plumb while top and bottom level. Fix the frame work by screwing into the reveals and jambs. Hacking the bottom part slightly recesses the framework for it to be flush with floor.

After the aluminum sliding door framing is in place, assemble the fixed part. Take the glazing and tie the frame round, it while inserting the rubber lining. Slide this panel and screw it into the frame firmly. Start sliding panel assembly and fix glazing as before, insert the rollers and push into the guiders. Let the panel roll along to the fixed side. screw adjust the wheels by pushing them up or down. Clean debris on guiders and remove dust.

Now that aluminum sliding door is assembled, place correctly each panel. Ensure that the fixed panel is on the outer guider and sliding part in the inside one. This prevents draught during windy days. Add the linings on the grooves provided to stop shaking during windy days or when opening. Add the locking latch and test the mechanism when inside and outside the room. Fix the alarm system if provided on moving panel and frame,then clean the door.
