Features of 5000 series
1. Can be referred to as aluminum and magnesium alloys. The main elements for magnesium, magnesium content between 3-5%.
2. Non-heat-treatable alloy
3. Low density, high tensile strength, elongation rate is high. Good corrosion resistance, good weldability, cold workability is good.
Aluminum plate with the national standard (GB/T 3880-2006), is applicable to the unity of the aluminum alloy plate material standards.

The surface quality
1, the surface is not allowed to have crack, corrosion spots and nitrate.
2, on the surface, allowing a depth of no more than 8% of the nominal size peeling defect part wall thickness, air bubbles, surface roughness and the local mechanical damage, but the defects cannot be more than 0.5 mm, maximum depth defect sheet with a total area of no more than 5% of the total area.
3, allow the supplier polishing along the longitudinal profiles until the surface is smooth.
4, other requirements: disucssed by both sides.
