5083 Tight Tolerance Aluminum Sheet

The strict control of impurities, alkali metal elements and low melting point elements of 5083 tight tolerance aluminum sheet improves the corrosion resistance and creep resistance of the alloy. Both sides of the plate are milled and processed to present an ultra-flat and fine surface. The dimensional tolerance standard is the world’s leading standard. It can be protected by double-sided film protection. The strength exceeds that of similar European products. The thickness specification coverage is high (≥4.5mm). The tensile strength of homogeneous alloy: 270~300MPa; Yield strength: 110~130MPa; Elongation after fracture: ≥ 12.0%; Brinell hardness: ≥70HBW, milling surface roughness Ra≤0.4µm.
