Aluminized Steel Coils (Type 1)

Aluminized Steel Coil Slitting

Aluminized steel sheet (Type 1) is made from a Cold Rolled substrate, upon which a hot-dipped Aluminum-Silicon coating is applied to both sides. It offers excellent resistance for applications in which a combination of heat and corrosion resistance is required. Aluminized sustains heat and oxidation protection up to about 900° F. without discoloration, while maintaining its strength up to about 1200° F. It generally affords about twice the corrosion protection of hot-dipped galvanized, however, unlike Galvanized, Aluminum is not self-sacrificial. As such, cut edges or other uncoated areas will exhibit rust. Aluminized has a silvery-satin smooth appearance.

Major end-uses include automotive mufflers, toasters, ovens, heaters, broilers, heat shields, fireplaces and chimney linings. It is normally produced in accordance with ASTM A463 standards and tolerances.
