Aluminium is a silver colored metal with lightweight properties, making it good for certain construction. Industrial aluminum is used worldwide and its production and supply heavily influence economics everywhere. Aluminum alloys are also produced for use in machinery, automobiles, and as a chemical additive. Engineering aluminum can be tricky, and requires an experienced technician who has dealt with the metal. An aluminum castings manufacturer can create specialty parts. An alloy is a material made up of two or more metals. Alloys are designed and produced having certain specific, desirable characteristics, including strength, formability, and corrosion resistance. Some of the common elements alloyed with aluminum include copper, manganese, silicon, magnesium and zinc. Typical applications and uses of aluminum alloys include building products (siding and structural), rigid and flexible packaging (foil, food and beverage cans) and transportation (automobiles, aircraft, and railcars). Aluminium alloys are readily fabricated. They are amenable to all casting processes. They can be rolled to any desired thickness with pure aluminium foil production down to the thickness of 6µm. A wide range of forgings are produced using extruded and cast bar and standard forging equipment. There is almost no limit to the different shapes to which the metal may be extruded. All of the aluminium alloys are easily machinable by standard techniques such as turning, milling, boring etc. Adjustment needs to be made to machining speeds and cuts when machining both cast and wrought product if the optimum finish is to be achieved.
