3A21 Aluminium Sheet

  • 3A21 aluminium sheet is a typical 3 series Al-Mn anti-rust alloy, the A here represents an improvement on the original pure aluminium, however, 3A21 aluminium sheet is also a non-heat treated alloy, and can only be enhanced by cold machining. Besides, due to the addition of the main alloy Mn, 3A21 aluminium alloy has the characteristics of excellent corrosion resistance, good formability and weldability, and appropriate strength, etc., so it is widely used in both these properties and the conditions requiring higher strength than the 1-series alloy, or the low-load parts working in liquid and gas medium, etc.
  • With decades of aluminium sheet production experience, CHAL is able to produce and supply high-quality 3A21 aluminium sheet of different sizes and tempers.
