CHARACTERISTICS |
APPLICATIONS |
|
ALCOSTA |
- Very fine grains due to the
suppression of the growth of
aluminum crystal during solidification
of aluminum melt (5 to 10% silicon
contained)
- Uniform surface condition and
excellent corrosion resistance
resulting from the sacrificing effect of
aluminum.
- Good appearance after painting
|
- Household
thermal
Equipment
- Car Mufflers

HEAT RESISTANCE
The heat resistance of ALCOSTA is excellent compared to that of zinc-coated steel sheet, galvannealed steel sheet, and cold-rolled steel sheet. Absolutely no changes in appearance and discoloration are observed even under extended exposure to the temperature of 450°C. At temperatures higher than 450°C the coating material transforms to aluminum iron alloy layer so that heat resistance and corrosion resistance are preserved even if discoloration occurs. the coating maintains its sacrificial properties up to the temperature of approximately 600°C.
