Henan signi aluminium 1100 H14 /3003 H14 epoxy painted aluminum sheet substrate size: thickness 0.2-1.5mm width 600-1850mm，1100 H14 /3003 H14 epoxy painted aluminum sheet thickness: single coating 4-20 micron double coating 25-28 micron 3 coating 35-38 micron
1100 H14 epoxy painted color coated aluminum sheet is a general industrial pure aluminum containing 99.0% aluminum. It is not heat-treated and has low strength but good ductility. Formability, weldability and corrosion resistance; after anodizing, the corrosion resistance can be further improved while obtaining an aesthetically pleasing surface.
3003 H14 epoxy painted color coated aluminum sheet is AL-Mn alloy, which is the most widely used rust-proof aluminum. The strength of this alloy is not high (slightly higher than industrial pure aluminum), and it can not be heat-treated and strengthened. Therefore, cold working method is used to improve its mechanics. Performance: It has high plasticity in the annealed state, good plasticity in semi-cold hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability and poor machinability. 3003 H14 epoxy painted color coated aluminum sheet has ROHS-certified epoxy, polyurethane and polyester coatings are made of backing, primer and topcoat respectively. The surface of the metal plate is coated with a layer of organic polymer. As a metal coated board for home appliances, the bonding performance of epoxy coatings is better, but compared to polyester, epoxy coatings are brittle, and 90 degree bends do not crack.
