2A12 Aluminum PlateA high-strength hard aluminum alloy, capable of being heat-treated for strengthening.2A12 aluminum plateGood spot welding performance; prone to intergranular cracking during gas welding and TIG welding.2A12 Aluminum PlateAfter cold working hardening, good machinability remains. Corrosion resistance is not high, so anodizing and painting methods or surface aluminum cladding are commonly used to enhance corrosion resistance.
Typical Applications:
2A12 Aluminum PlatePrimarily used for manufacturing various high-load components and structures (excluding stamping and forging parts), such as aircraft frame parts, skin, bulkheads, wing ribs, wing spars, rivets, etc., for operation at temperatures below 150°C.
