Aluminium composite panel, Fluorocarbon PVDF cladding panel is made of a mixture of fluorocarbon resin with fluorine enyne as the basic monomer, paint, alcohol ester solvent and accessory ingredients.
Aluminum-magnesium alloy is the combination of the major element-aluminum and small quality of magnesium or other metallic materials for strengthening the hardness. Due to its metallic property，the heat conductivity performance and the intensity are particular obvious. Meanwhile，the alloy is relatively of high flexibility and bending and abrasion-resistance. It is light weighted and of low density and of strong anti-press property. Due to magnesium，the alloy has great anti-corrosion property. So the material can be largely applied in the outdoor building decoration with large scale.
Aluminum-manganese alloy：the element of the alloy is manganese，which has excellent forming performance，high corrosion-resistance，fine welding property and electrical conductivity. Its anti-press intensity is much higher than 1100.This kind of alloy can be applied in signs and washing machines cylinder shell.
FEITENG products are the once formation on the continuous extruding composite production line. The positive and negative aluminum material，adopting Alu-Mn or Alu-Mg alloy materials，connect the plastics with the core material fully by the polymer adhesive resin. Due to the excellent extension，manufacturing property and relatively high surface hardness guaranteed by the Alu-Mn or Alu-Mg alloy materials，the aluminum composite panel，which is well to be installed and manufactured，is widely applied in advertising signs and curtain wall decoration.
