ASTM A463 Aluminized Steel

ASTM A463 Aluminized Steel

Characteristics

ASTM A463 aluminized sheet is a hot dipped, aluminum – silicon alloy coated steel with a coating weight up to T1-40.  It will provide long-term service up to 1250 degrees F and will reflect approximately 80% of radiant heat up to 900 degrees F.  In addition, it exhibits good general corrosion resistance. Moderate forming, drawing, and spinning will not normally flake or peel the aluminum-silicon coating.

Applications

Used for high heat applications, A463 is used for firewalls, heaters, incinerators, ovens, dryers and their housings.
