ASTM 2A12 LY12 5754 1070 Solid Aluminum Bar Alloy Anodized Casting Extrusion

ASTM 3003 1060 6026 6061 5083 7085 5A06 2A12 LY12 5754 1070 Casting extrusion alloy anodized aluminum round square rod 

The common plate standard for 2024 is AMS-QQ-A-250/4 (non-aluminum-clad); AMS-QQ-A-250/5 (aluminum-clad), and the alloying element of 2024 is copper, which is called duralumin and has a very high High strength and good machinability, but poor corrosion resistance. It is widely used in aircraft structures (skin, skeleton, rib beam, bulkhead, etc.), rivets, missile components, truck hubs, propeller components and other various structural parts. It is Al-Cu-Mg system.

2024 is a typical hard aluminum alloy in the aluminum-copper-magnesium series. Its composition is relatively reasonable and its comprehensive performance is better. Many countries produce this alloy, which is the largest amount of duralumin. The characteristics of this alloy are: high strength, certain heat resistance, and can be used as working parts below 150°C. At temperatures above 125°C, the strength of the 2024 alloy is higher than that of the 7075 alloy. The forming properties in the hot state, annealing and new quenching state are relatively good, and the heat treatment strengthening effect is remarkable, but the heat treatment process requirements are strict. The corrosion resistance is poor, but it can be effectively protected by cladding with pure aluminum; it is easy to produce cracks during welding, but it can be welded or riveted by a special process. Widely used in aircraft structures, rivets, truck hubs, propeller components and various other structural parts.
