MATRIX AL4043

MATRIX Aluminum Wire AL4043, classified as ER4043, is a high-quality aluminum-silicon filler metal widely used in MIG and TIG welding applications. Composed primarily of aluminum with approximately 5% silicon, this wire offers excellent weld ability, low melting point, and smooth bead appearance, making it a preferred choice for a wide range of fabrication and repair jobs.

ER4043 aluminum wire is especially effective when welding 6XXX series aluminum alloys such as 6061, 6063, and 3003. Known for its outstanding crack resistance and easy feeding characteristics, this wire produces high-quality, visually appealing welds with minimal spatter and good corrosion resistance under normal atmospheric conditions.
