●Aluminum alloy 2014 characteristics and scope of application:

の 2014 aluminum alloy is both a hard aluminum alloy and a wrought aluminum alloy in terms of composition. Compared with 2A50, it contains
The copper content is higher, so the strength is higher, and the thermal strength is better, but the plasticity in the hot state is not as good as 2A50, 2014
Aluminum alloy has good machinability, good contact welding, spot welding and roll welding performance, arc welding and gas welding
Poor energy; heat treatment can be strengthened, there is extrusion effect; corrosion resistance is not high, there is inter-test corrosion during artificial aging
tendency. Used in occasions requiring high strength and hardness (高温も含めて). Heavy Forgings, Plates and Extrusions
Materials are used in aircraft structural parts, multi-stage rocket first-stage fuel tanks and spacecraft parts, 車輪, truck frames
and suspension system parts. The corrosion resistance is poor, but it can be effectively protected by covering it with pure aluminum; it is easy to produce corrosion during welding
Cracks, but can be welded or riveted using special techniques. Widely used in aircraft structures (skin,
skeleton, rib beam, bulkhead, 等) リベット, ミサイル部品, truck wheels, propeller components and other structures
member.
