Characteristics and scope of application


2A12 aluminum alloy is a kind of high-strength hard aluminum, which can be heat-treated and strengthened; 2A12 aluminum alloy has good spot weldability, and there is a tendency to form intergranular cracks when using gas welding and argon arc welding; 2A12 aluminum alloy can be cut after cold work hardening Performance is still good. The corrosion resistance is not high, and the anodizing treatment and painting method or the surface is coated with an aluminum layer to improve the corrosion resistance

Applications


Uses are mainly used to make a variety of high-load parts and components (but not including stampings forgings) such as skeleton parts, skins, bulkheads, ribs, spars, rivets, etc. under 150°C


Delivery State


In general to heat treatment state of delivery, the type of heat treatment in the contract note; not indicated, according to the state of non heat treatment delivery
