Price per kg 2017 T4 T451 aluminum sheet is Al-Cu-Mg-based aluminum alloy in the first industrial application of hard aluminum alloy, its composition is reasonable, comprehensive performance. Aluminum production process using off-line quenching, natural aging state used more. However, the use of off-line quenching process is more cumbersome, the performance requirements of the heat treatment equipment is relatively high, and off-line quenching easily lead to local coarse grain, reducing the temperature of the solution is easy to cause the hardness is not enough.
In this paper, the effect of different heat treatment process and drawing rate on the performance of Price per kg 2017 T4 T451 aluminum sheet alloy bar was investigated by using reverse aluminum extrusion on-line quenching + drawing + artificial aging method to produce high precision and high hardness 2017 aluminum alloy bar.Through the heat treatment and drawing process optimization, to produce a product to meet user requirements.
Product technical requirements: alloy grade Price per kg 2017 T4 T451 aluminum sheet, product diameter φ16.1 ± 0.03mm, hardness ≥ Hv135, delivery length: 2500mm, bending: ≤ 0.6mm / 2500mm.
