7A04 Marine alloy Aluminum sheet plate belongs to the Al-Zn-Mg-Cu series of ultra-high-strength aluminum alloys, also known as super-duralumin, which is a fairly mature and widely used alloy among super-duralumin. High strength, good heat treatment strengthening effect, moderate plasticity in annealing and newly quenched states; different from duralumin, the corrosion resistance in artificial aging state is better than that in natural aging state, and the natural aging process is slower, it needs to go through 3 The age hardening peak can only be reached after months, so 7A04 is used in the quenched artificial aging state.



7A04 Marine alloy Aluminum sheet plate Performance advantage
1. Ultra-high-strength aluminum alloy, high hardness, strong corrosion resistance, and particularly good heat treatment strengthening effect;
2. After heat treatment, it has good machinability, good resistivity, spot welding and seam welding performance;
3. The surface of the aluminum plate has no peeling, bubbles, surface roughness and local mechanical damage, and the surface of the aluminum plate has no cracks, corrosion spots and traces of nitrate;
