Aluminum is one of the most used metals in today’s society – Aluminium Section Office in South Africa it can be found across a number of industries, such as construction and commercial, and in a number of applications, such as beverage cans and appliances. When choosing a manufacturer of aluminium extrusion for supplying the metal that you use in your workplace, however, it is important that you carefully consider which one will be best for your needs.
The manufacturer will begin by removing the aluminium from deep within the earth’s crust (either as bauxite ore or feldspar). Often, the Bayer’s method, Wohler’s method or Hall Heroult method is chosen to remove the metal in its molten form. It is then hardened and moulded into whatever shape the manufacturer desires. When the aluminium is extracted from the earth in its solid form, Stock Aluminum Extrusions it will be passed through a number of mechanical processes that are designed to give the metal its desired shape. These processes include: rolling, drawing, forging, spinning, piercing and extrusion.
Regardless of whether aluminium has been found in its molten or solid form, the manufacturer will then pass it through either a hot working or cold working process to prepare it for their customers. When using the hot working process (the most popular of the two), a billet will be heated to a temperature of over 79 degrees Celsius, which will allow the aluminium to be easily distorted and placed into its desired shape.
The reason for the popularity of the hot working process over the cold working one can be fully realized when you compare aluminium extrusion to squeezing toothpaste out of its tube. It is much easier to extrude the metal when it is malleable, meaning that it must have been heated to a certain temperature.
Finally, the aluminium will pass through an extrusion and drawing process that runs almost parallel to each other. This is the final step in the whole extrusion process and is the step that gives the metal its entire shape. Deep drawing, for example, is used give the metal a cup, conical tapered, cylinder and seamless tube shape. For less curved shapes, Aluminum Extrusion Framing Components the drawing process is skipped.
Once you are satisfied with the processes and methods utilized by a potential manufacturer of aluminium extrusions, you can begin submitting your orders with them. If, after your first delivery, you are still satisfied with the manufacturer based on the promptness of the order being filled and the quality of the aluminium that you receive, you can continue the relationship.

Aluminum doors are once popular in the home building industry. With the changes in architectural taste, however, many people opted for different styles of sliding doors. Nonetheless, even when the interest in this type of door has already declined, it still has various advantages that could not be provided by other types of doors.
For one, aluminum pocket doors are great space savers. They could be used in several instances when space is an issue. For example, a room which could not be fixed with a hinge door could make use of a pocket door. This is the case when there is a permanent obstruction along the pathway where the door swings. Since the door runs along a hidden track and vanishes inside a pocket in the wall, there is no longer a need to open the door fully by swinging. Thus, the door does not require more space before it could be opened. Also, a pocket door could effectively replace a standard door when there is no other way but hide the door inside the walls.
Aluminum sliding doors is also a great alternative to ordinary wood, vinyl or plastic doors. This is because the doors are predicted to capture the future trend in home designing alongside glass and other metals.
There are downsides to using the doors though. For one, these doors could not be used in places where there are extreme temperatures as aluminum tends to adopt to the temperature of its surrounding. This would not help neutralize the heat or the coldness inside a room, for example. Also, aluminum, unlike wood, glass and fiberglass doors, tends not to blend in with most architectural design. For instance, the doors would not work well with Victorian-style inspired homes. They are, however, common among conventional houses where steal panels and other metals are used in decorating the house.
Also, one cannot really play well with colors on the doors. Usually, homeowners have to settle with the metallic look. This doesn't say that the natural aluminum surface is not good. In fact it is. However, for people who are fond of playing with colors, the doors may not be the best choice.
Another drawback to using the doors is that they tend to catch the atmosphere of large kitchens since they are usually associated with the kitchen doors of most restaurants. But again, this may not be as bad at all since many people actually love to create a certain atmosphere in their kitchen that may only be contributed to metals.
A change of look is what a sliding door could give when used in residential homes. In the industrial settings however, they have become the mainstay.

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:
Radiators (clean and contaminated)
Extrusions (clean and contaminated)
Wheels (Clean and Chrome Plated)
Aluminum/Copper Radiators (clean and contaminated)
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.
