What Is Aluminized Exhaust Pipe

Aluminized steel is mild steel that has been coated with an aluminum-silicone alloy. The silicone helps the aluminum stick to the steel. The aluminum then resists corrosion.

What's better aluminized or stainless steel exhaust?

When it comes to corrosion resistance and overall strength, stainless steel comes out trumps. As compared to aluminized steel, it is durable and does not rust. In case of aluminized steel, if the aluminum coat peels off or is broken, it can get corroded.

Can you weld aluminized exhaust pipe?

You can weld aluminized tubing with gas metal arc welding (GMAW) using ER70-S6 mild steel filler metal and 75 percent argon/25 percent oxygen shielding gas, but this will leave the finished weld zone unprotected because the aluminum will be burned away.
