Similarly, 2A12 aluminum sheet is a 2 series Al-Cu alloy, which mainly contains the alloy component Cu, and belongs to the heat-treated alloy sheet. Therefore, the 2A12 aluminum alloy strengthened by heat treatment has high strength. In addition, 2A12 aluminum sheet has excellent machinability and good spot welding property, but when gas welding and argon arc welding, there is a tendency to form intergranular cracks. And the corrosion resistance is not high, need to carry out surface treatment or aluminum coating to improve its corrosion resistance. Now, 2A12 aluminum sheet is mainly used for making various parts and components with high load (but not including stamping parts and forgings). Here, Mingtai 2A12 aluminum processing technology far beyond the national standard, and provide the original factory warranty. So, we can be assured to use and purchase!
1. High Fatigue Strength. 2A12 aluminum sheet can be subjected to an almost infinite number of alternating loads without failure.
2. Excellent Machinability. After cold hardening, the machinability of 2A12 aluminum sheet is good .
3. Mechanical Properties. 2A12 aluminum alloy tensile strength σb (MPa)≥410, conditional yield strength σ0.2 (MPa)≥265, elongation δ5 (%)≥12.
In conventional applications, 2A12 aluminum sheet is mainly used in molds, traffic vehicles, compressors, rivets, truck hubs, screw elements and other structural parts.
2A12 Aluminum Sheet for Aircraft Manufacturing
In aircraft manufacturing, 2A12 aluminum sheet is mainly used for skeleton parts, skin, diaphragm, wing ribs, wing spars, rivets and other parts working below 150 ℃.
