5052 5 bar checker plates Tread plate Aluminum plate

Short Description:

5052 checker plate main chemical ingredients:
Iron Fe Si Si (0.25), (0.4), copper Cu (0.1), manganese Mn (0.1), magnesium Mg (2.2 2.8), chromium (Cr (0.15 0.35) zinc zinc (0.1), the typical mechanical properties of alloy main deformation: the tensile strength of 25 ℃ (Mpa) - 230,Yield tension (25℃MPa) -- 195, hardness 500Kg force 10mm ball -- 60, elongation 1.6mm(1/16in) thickness -- 12..The typical physical properties of the main deformation of the alloy are: thermal expansion coefficient (20-100 ℃)-23.8, melting point range: 20607 -- 650.Conductivity: 20 ℃ (68 ° F) - 35, the electric resistance of 20 ℃ (68 ° F) - 0.050, density (20 ℃) - 2.68.The product has strong corrosion resistance, and its comprehensive properties (A), stress corrosion crack (B), weldability (F) including gas shielded welding and arc welding all meet the standards of A
5052 checker aluminum plate surface quality requirements:
1, the surface is not allowed to have cracks, corrosion spots and nitrate traces.
2. The surface is allowed to have peeling, bubbles, surface roughness and local mechanical damage with a depth of no more than 8% of the nominal size of the wall thickness of the defect location, but the defect depth can not exceed 0.5mm, and the total area of the defect shall not exceed 5% of the total area of the plate.
3. Allow the supplier to polish longitudinally along the profile until the surface is smooth.
4. Other requirements: the demander and the supplier shall formulate by themselves
