Aluminised Tube | ACMS

Quality and Properties

The aluminised coating is applied to the steel strip through a continuous hot-dip process, in which the base material is immersed in a bath of molten aluminium-silicon alloy. This creates a metallurgically bonded surface layer that resists oxidisation and scaling at elevated temperatures while maintaining excellent coating adhesion during forming and welding operations.

The resulting tube combines the strength and formability of mild steel with the heat and corrosion resistance of the aluminium-silicon coating, making it well suited to exhaust manifolds, mufflers, intermediate and tail pipes and other components exposed to heat and corrosion prone environments.

Applications

Precision Tube manufactured from Aluminium-Silicon-Coated Mild Steel (ACMS) is typically used for automotive exhaust systems due to its heat resistance, reflectivity, weldability, formability and corrosion protection. Also available in Perforated.

Aluminised tube is also used in machinery and equipment where heat and corrosion resistance are required without the cost of stainless steel, such as heater assemblies, ventilation systems and engine-bay ducting.
