Rust-proof aluminum alloy extra-wide aluminum plate extra-long aluminum spot & rust-proof aluminum alloy extra-wide aluminum plate extra-long aluminum spot aluminum alloy grade
It has the characteristics of medium strength, good corrosion resistance, weldability and easy processing and forming. It is Typical alloys in the series alloys. Abroad, different heat treatment states are the main materials used in the automobile manufacturing industry (car doors, molds, seals) and canning industry. Scope of application: Widely used in welded structures, storage tanks, pressure vessels, ship structures and offshore facilities, transportation tanks and other applications requiring excellent processing performance, excellent corrosion resistance, high fatigue strength, high weldability and medium static strength. occasion. No cracks, corrosion spots or traces of salt nitrate are allowed on the surface of the aluminum plate. , The surface is allowed to have peeling, bubbles, surface roughness and local mechanical damage with a depth not exceeding % of the nominal wall thickness of the defective part,
but the maximum depth of the defect cannot exceed., and the total area of defects does not exceed the total area of the plate. of%. , The supplier is allowed to polish the profile longitudinally until the surface is smooth. , Other requirements: The demander and supplier can formulate their own chemical composition: Silicon copper: . > Magnesium: .~ Zinc: Manganese: Chromium: Iron: .
