Aluminized-silicon Steel Coil ASTM A463 AS240g for Insulation Application
Hot dip Aluminized / Aluminium-Silicon (AS) coating steel is produced by immersing the prepared strip in a molten bath of Aluminium-Silicon. The composition of the bath consists of 8% to 11% silicon and the balance is aluminium.
Aluminized steel is carbon steel coated through the hot-dip process with an aluminum-silicon alloy. The aluminum coating provides excellent resistance to high temperatures and a bright appearance, while the silicon promotes better adherence of the coating to the base metal.
Aluminized sheet and coil maintain their bright appearance and provide long-term service at temperatures up to 900 degrees F — a significantly higher temperature than comparable zinc-coated products can withstand. Although aluminum corrodes faster than zinc, the oxide layer that forms on aluminum adheres tightly, effectively protecting the base metal.
