Alloy 5086 aluminum plates have even higher strength than 5052 or 5083 and its mechanical properties vary significantly with hardening and temperature. It is not strengthened by heat treatment; instead, it becomes stronger due to strain hardening or cold working of the material. This alloy can be readily welded, retaining most of its mechanical strength. The good results with welding and good corrosion properties in seawater make Alloy 5086 extremely popular in marine applications. Alloy 5086 has been used in vehicle armor plate due to its high strength factor.

Performance advantage
1. High corrosion resistance, medium strength, good weldability;
2. Low density, high tensile strength, high elongation;
3. Aluminum plate surface no oil spots, no waves, no scratches, no roller printing, no burrs.
