Hot dip aluminum-zinc plate/coil
Galvanized zinc layer is made of aluminum alloy composed of aluminum and zinc, from 55% aluminum, 43% zinc and 2% silicon in the solidification and high temperature 600 ℃, whose entire structure is made of aluminum - iron - silicone - zinc, forming dense of a quaternary alloy crystals.
1,Features:
Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside.
Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover.
Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials.
Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.
2 Application:
Building: roof, wall, garage, wall insulation, pipe and modular housing
Automotive: muffler, exhaust, wipers, accessories, fuel tanks, truck boxes, etc.
Appliances: refrigerator back, gas stove, air conditioning, electronic microwave oven, LCD frame, CRT with explosion-proof, LED backlight, electrical cabinets,
other: off heat insulation cover, heat exchangers, dryers, hot water etc.
