Aluminium-conductor steel-reinforced cable ACSR is galvanized steel, but zinc, 5% or 10% aluminium alloy and trace mischmetal coated steel (sometimes called by the trade-names Bezinal or Galfan) and aluminium-clad steel (sometimes called by the trade-name Alumoweld) are also available. Higher strength steel may also be used. In the United States the most commonly used steel is designated GA2 for galvanized steel (G) with class A zinc coating thickness (A) and regular strength (2). Class C zinc coatings are thicker than class A and provide increased corrosion protection at the expense of reduced tensile strength. A regular strength galvanized steel core with Class C
Aluminized steel Aluminized steel Aluminized steel is steel that has been hot-dip coated on both sides with aluminium-silicon alloy. This process assures a tight metallurgical bond between the steel sheet and its aluminium coating, producing a material with a unique combination of properties possessed neither by steel nor by aluminium alone. Aluminized steel shows a better behavior against corrosion and keeps the properties of the base material steel for temperature lower than . For example, it is commonly used for heat exchangers in residential furnaces, commercial rooftop HVAC units, automotive mufflers, ovens, kitchen ranges, water heaters, fireplaces, barbecue burners, and baking pans.
