3103 Aluminum Alloy Bar

 

3103 aluminium alloy is a commercial aluminium which is close in properties to 3003. With very good resistance to atmospheric corrosion and excellent mechanical properties, 3103 is a versatile alloy which is used in the aerospace, oil and gas industry and automotive sector amongst others. The material has improved mechanical properties over 1000 series aluminium alloys, especially at elevated working temperatures. This feature widens the use of the alloy as a construction cladding material.
