Aluminum zinc plate is widely used in building materials, home appliances, automobiles, environment, machinery, ships and many other fields of an alloy coating plate. Aluminium zinc steel plate is covered in aluminum zinc alloy steel plate surface treatment, aluminum, zinc and 43.4% 55% from 1.6% silicon at 600 ℃ high temperature solidification and composition, its whole structure by aluminum - iron - silicon - zinc, forming dense four yuan form crystal of an alloy coated steel.
An overview of the
Aluminum zinc plate has many excellent characteristics:
Corrosion resistance
The corrosion resistance of "aluminum zinc coated steel coil" is mainly due to the protection function of aluminum. When the zinc is worn, the aluminum forms a dense layer of alumina that prevents the corrosion resistant material from further corroding the interior.
Heat resistance
Aluminum zinc alloy steel plate has good heat resistance, can withstand more than 300 degrees Celsius high temperature, and aluminum plated steel plate is very similar to the resistance to high temperature oxidation, often used in
Chimney tubes, ovens, illuminators and lampshades.
Heat reflective
Aluminum - and zinc-coated steel has a high reflectance, twice that of galvanized steel, and is often used for insulation.
economy
Because the density of 55% al-zn is smaller than the density of Zn, so in the same weight and the same thickness of the gold-plated layer, the area of aluminum zinc plate is more than 3% larger than galvanized steel plate.
