Product Description
2A12(LY12-CZ) is a typical hard aluminum alloy in the ALCuMg system of Al-Cu-Mg, which can be strengthened by heat treatment with reasonable composition and good comprehensive properties. It is the largest amount of duralumin. The alloy is characterized by high strength, certain heat resistance, and can be used as working parts below 150°C. At temperatures above 125°C, 2A12 alloys are stronger than 7075 alloys. The formability in hot state, annealing state and new quenching state is better, and the heat treatment strengthening effect is remarkable, but the heat treatment process is strict. The corrosion resistance is poor, but the coating with pure aluminum can be effectively protected: cracks are easy to occur when welding, but special processes can be welded and riveted.

Handling method |
1. Oxide layer appears on the surface of the alloy: the oxide layer can be removed by pickling or polishing and then anti-corrosion treatment. 2. The alloy strength does not meet the requirements: the strength of the alloy can be adjusted by heat treatment or cold working. 3. Cracks in the alloy: may be caused by defects in the material or excessive stress during processing, and reasonable process adjustment should be made. 4. The alloy surface is dented or scratched: the defects on the alloy surface can be repaired by polishing or spraying. |
