Independently developed and produced by Shanghai Perfect Industry Co., Ltd., 7xxx Serious Aluminum Alloy Bars are high-strength structural metals based on an aluminum-zinc-magnesium alloy system. With aluminum content typically above 87%, the main alloying elements are zinc (zinc content 5%-10%) and magnesium (magnesium content 1%-3%), and copper can be added as an auxiliary alloying element (copper content 0.2%-2.0%) according to performance requirements. The synergistic effect of zinc and magnesium forms strengthening phases, which significantly improve the alloy's mechanical strength after heat treatment. Trace elements such as zirconium or chromium are also added to optimize grain structure and enhance corrosion resistance. Endowed with excellent high strength, good fatigue resistance, and reliable machinability, these bars are widely used in fields requiring high structural performance and load-bearing capacity, serving as a core material for aerospace, automotive lightweight structures, high-pressure vessels, and precision mechanical components.
1.Superior high strength and excellent fatigue resistance, suitable for high-load-bearing scenarios
2.Excellent machinability, adapting to precision processing requirements of complex components
3.Controllable corrosion resistance, with optimized performance through special heat treatment and surface treatment
4.Flexible customization of heat treatment states to match diverse application performance needs
5.High cost performance with stable high-quality and competitive pricing for high-strength grades
6.Authoritative quality certification and complete full-process product traceability system
