3103 Aluminium Sheet

Excellent corrosion resistance.

3103 is a low to medium strength aluminium alloy that offers excellent resistance to corrosion.

3103 aluminium sheet is a low to medium strength product which provides excellent corrosion resistance.

3103 is a low to medium strength aluminium alloy that combines excellent resistance to corrosion with good formability. 3103 is commonly supplied in the H14 temper and offers similar properties when compared to 3003. The material displays improved mechanical properties when compared to 1xxx series aluminium alloys, particularly at elevated temperatures. Welding of 3103 aluminium sheet is also very good, as is corrosion resistance to atmospheric attack.


Stock Availability

We stock 3103 aluminium sheets in a broad range of thicknesses with tempers, including H14, H16, H26 and O, with H14 being the most common.
