ER4043, commonly referred to as "AlSi5", contains 5% silicon, and is the oldest and one of the most widely used aluminum welding rods for general-purpose applications. The silicon additives help to improve the fluidity and reduce sensitivity in welding cracking. Its bright weld finish makes it a popular choice for welders. ER4043 is used where base metal requires thermal treatment, and it also can be used in welding forge and casting materials. This welding rod is suitable for welding various grades of aluminum like 3003, 3004, 5052, 6061, and 6063, as well as casing alloys like 43, 355, 356, and 214.
