ER4043, commonly referred to as "AlSi5", contains 5% silicon, and is the oldest and one of the most widely used aluminum welding wires for general-purpose applications. The silicon additives help to improve the fluidity (wetting action) of the weld pool and reduce sensitivity in welding cracking. Its bright weld finish makes it a popular choice for welders. ER4043 is suitable for welding various grades of aluminum like 3003, 3004, 5052, 6061, and 6063, and casing alloys like 43, 355, 356, and 214.
