Aluminum silicon alloy welding wire ER4043

Explanation: SAlSi-1 (ER4043) is a series of aluminum and silicon welding wire, suitable for welding 6061 and other 6000 series aluminum alloys, heat-treated alloys of the 2000 series, and cast aluminum. SAlSi-1 (ER4043) contains 5% silicon, which has good fluidity at welding temperatures. The weld metal has excellent resistance to thermal cracking, but its plasticity and toughness are low. After anodic treatment, it will be darker than the substrate, presenting a gray color. When welding 5000 series aluminum magnesium alloys with aluminum silicon alloy, it is easy to form brittle Mg2Si compounds, reducing the ductility and corrosion resistance of the joint. Therefore, this welding wire is generally not used for welding aluminum magnesium alloys. When welding 6061-T6 aluminum alloy with SAlSi-1 (ER4043), the tensile strength of the joint can reach more than 167MPa.

The mechanical properties of the deposited metal -- 6061-T6 aluminum alloy welded with SAlSi-1 (ER4043).

Approximate Melting Range: 573~632℃

Joint anti-tensile strength: above 167MPa

After anodization, the color is gray.
