2A12 ALUMINUM SHEET
Detailed Information
As a result, 2A12 aluminum alloys strengthened by heat treatment have high strength. In addition, while 2A12 aluminum panels have excellent machinability and spot-welding properties, they are susceptible to the formation of grain boundary cracks during gas and argon arc welding. In addition, the corrosion resistance of 2A12 aluminum panels is low, and surface treatment or aluminum plating is required to improve corrosion resistance. Today, 2A12 aluminum sheets are mainly used to manufacture a variety of parts (but not stampings and forgings) that are subject to high loads. 2A12 aluminum plates have high fatigue strength and can withstand an almost unlimited number of alternating loads without failure, and after cold hardening, 2A12 aluminum plates have a high fatigue strength. Aluminum plate has good machinability.

Application
2A12 aluminum sheets are mainly used for molds, transportation tools, compressors, rivets, truck hubs, screw components and other structural parts. . In aircraft manufacturing, 2A12 aluminum sheet is used for skeleton parts, skins, bulkheads, wing ribs, spars, rivets, and other parts in the 150-mm range. Parts that work below °C.
