2A12 T4 Extruded Aluminum Bar Hexagonal/Square/Round Alloy: 2A12 Temper: T4 Diameter: 40mm-350mm Standard: GB/T 3190 Product Description 2A12-T4 is a typical hard aluminum alloy in the aluminum-copper-magnesium system. Its composition is reasonable and its comprehensive performance is good. Many countries produce this alloy, which is the largest amount of duralumin. The characteristics of the alloy are: high strength, certain heat resistance, and can be used as working parts below 150°C. When the temperature is higher than 1259C, the strength of 2A12-T4 alloy is higher than that of 7075 alloy. The formability is better in hot state, annealing and new quenching state, and the heat treatment strengthening effect is remarkable, but the heat treatment process is strict. The corrosion resistance is poor, but it can be effectively protected by coating with pure aluminum; cracks are easy to occur during welding, but it can be welded or riveted by a special process. Widely used in aircraft structure, rivets, truck wheel hubs, propeller elements and various other structural parts. * Remarks: Specific requirement of alloy, temper or specification can be discussed at your request.
