2A12 Aluminum BarProduct Description
2A12 Aluminum RodA high-strength hard aluminum alloy, capable of heat treatment for strengthening.2A12 Aluminum RodGood spot-welding performance; prone to form intergranular cracks when using gas welding and TIG welding.2A12 Aluminum RodAfter cold working hardening, good machinability remains. Corrosion resistance is not high, so anodizing and painting methods or adding an aluminum layer to the surface are commonly used to enhance corrosion resistance.
Typical Applications:
2A12 Aluminum RodPrimarily used for manufacturing various high-load components and structures (excluding stampings and forgings), such as aircraft frame parts, skin, bulkheads, wing ribs, wing spars, rivets, etc., operating at temperatures below 150°C.
