Aerotech Alloys produces aluminum bar by several processes, including rolling and coiling, extrusion or drawing directly from molten aluminum. It can then be machined into many different applications. It is available in flat, rounded or square shapes in a variety of sizes, and is used for stamping, machining or casting a finished product.
Aluminum bar is most commonly available in 6061, 6082 and 6063 alloys.
- 6061 aluminum alloy - One of the most common aluminum products on the market, it provides good structural strength, toughness, a good surface finish and excellent corrosion resistance to sea water and general atmosphere. It is easily machinable, and is also easy to join and weld. It is heat treatable and is used extensively in construction applications in the aircraft, marine and automotive industries. It is lightweight and accepts coatings and paint easily.
- 2024 Aluminum Bar - Copper is the main alloying ingredient in 2024, making it extremely strong. Although it is not generally considered weldable, 2024's impressive resistance to fatigue makes it the preferred choice for applications where extended periods of stress are likely. It is popular in the aerospace industry as it has a high strength to weight ratio. It is non magnetic and heat-treatable, and is often used in gear shafts, wheels and bolts.
- 7075 Aluminum Bar - 7075 is a zinc and copper "aircraft grade" aluminum alloy that is stronger than most mild steels. It has good resistance to fatigue and displays average machinability. It is also resistant to corrosion and anodizing but, like 2024, is not considered weldable.
