Aluminium Wire for GMAW (MIG)

ER4043
4043 is one of the most widely used general-purpose aluminium welding alloys containing silicon to lower the melting point and improve fluidity and wetting action. 4043 produces a bright weld with very good appearance and offers excellent resistance to weld cracking.

ER5356
5356 is the most popular of the high-magnesium welding filler metal alloys and is typically chosen for its relatively high strength and good feedability characteristics. 5356 has high
compatibility with many base metals and is suitable for many applications, but is not recommended for elevated temperature service above 65°C (150°F).
