Product Characteristics
A. High temperature resistance: Because of the special combination
of steel plate substrate and coating structure, an iron-aluminum
alloy is formed, which makes the aluminized plate have excellent
high temperature resistance. High reflectivity can be guaranteed at
450 C. When the temperature is higher than 480 C, the appearance of
the coating is grey. The protective layer against oxidation of
steel sheet is still well preserved at 650 C without any falling
off.
B. Heat Reflectivity: At 480 degrees Celsius, the aluminized sheet
can reflect 80% of the heat input. Therefore, the aluminized sheet
can be used as an efficient heat insulation barrier or a heat
reflector in high temperature applications, which can rapidly
increase the temperature in the furnace by effective heat
reflection.
C. Mechanical Strength: At room temperature, the mechanical
strength of aluminized sheet is the same as that of its base
material. At the same temperature of 480 C, the strength of
aluminized steel sheet is 10 times than that of aluminium sheet, so
the thickness of steel sheet can be reduced by at least 30%.
D. Corrosion resistance: During hot dipping, molten aluminium
reacts immediately with oxygen in the air to form an Al2O3
protective layer, which passivates the surface of steel plate
immediately. The protective layer is very stable and insoluble in
water. Even if the surface of the steel plate is scratched later,
the protective layer has self-healing function. Therefore, the
aluminized sheet has very strong corrosion resistance to chemical
corrosion.
E. Ecological characteristics: Aluminum-Coated-Silicon Steel Sheet
without chemical passivation has no effect on health, so it can be
used in food processing. Testing reports from many professional
groups confirm that it is environmentally friendly. Aluminum plated
sheet can be recycled completely. Aluminum plated sheet can be
comparable to stainless steel, but the price is only about one
third of that of stainless steel. It is widely used in automobiles,
motorcycle mufflers, exhaust pipes and fuel tanks. 2. Burning
furnace, heat exchanger, dryer, air conditioner, etc. 3. Household
water heaters, gas stoves, breadboxes, chimneys, microwave ovens,
food processing machinery, electric ovens, cooking utensils. It can
also be used for building covers, walls, roofs and other insulation
components.
F. Others: Standard MAG and TIG welding can be used. It can be used
for drawing, stamping, drawing and other forming processes.
Coatings have durable gloss, better corrosion resistance and
weathering resistance
