2A12 Aluminum Sheet Plate

2A12 aluminum is an aerospace-grade aluminum alloy known for its high strength and good machinability. It belongs to the 2xxx series of aluminum alloys, which are characterized by their copper content. The addition of copper provides enhanced strength and heat treatability to the alloy.
2A12 aluminum sheet plate has a high tensile strength and excellent resistance to fatigue, making it suitable for aerospace and military applications. It is commonly used in the construction of aircraft structures, such as wing spars, fuselage frames, and bulkheads. Its strength-to-weight ratio makes it ideal for parts that require both strength and lightness.

The machinability of 2A12 aluminum is another advantage. It can be easily machined, allowing for the production of complex parts with tight tolerances. This makes it a preferred choice for applications that require intricate machining operations, such as aircraft components, precision parts, and molds.
In addition to aerospace applications, 2A12 aluminum sheet plate finds uses in other industries as well. It is employed in the manufacturing of high-strength structures, marine components, and automotive parts. Its corrosion resistance makes it suitable for marine environments, while its strength properties make it ideal for heavy-duty applications.
