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
