Sifmig 8 MIG Brazing Wire – 1.0 mm x 4 Kg

Description

Sifmig 8 MIG Brazing Wire – 1.0 mm x 4 Kg

The Sifmig 8 is a phosphor bronze wire enriched with 7% tin. It’s specifically designed for fusion welding of phosphor bronze castings, copper alloys, and brass. Additionally, it’s suitable for MIG brazing on a variety of metals, including ferrous, stainless, and dissimilar metals. This wire is also employed to apply a bearing surface, providing a wear-resistant layer on surfaces prone to abrasion.

Key Features:

• Phosphor Bronze with Tin: Contains 7% tin, enhancing its welding capabilities.
• Versatility: Suitable for MIG brazing on various metals and for applying bearing surfaces.
• Crack Repair: Ideal for repairing cracks in castings and enhancing wear resistance on surfaces.

Applications & Recommendations:

• Welding & Brazing: Perfect for fusion welding of phosphor bronze castings, copper alloys, and brass.
• Bearing Surface: Can be used to apply a bearing surface on different metals.
• Lead Containing Metals: When the parent metal has trace amounts of lead (e.g., LG2), it’s recommended to apply SIFMIG 8 in stages. Grinding between passes is essential to eliminate lead from the joint and minimize porosity.

Specification

Welding Positions

Weldable in all positions and particularly useful in hard-to-reach areas. Ensure surfaces of parent metal are cleaned thoroughly before welding.

Welding Recommendations:

• Welding Positions: This wire is weldable in all positions, making it especially useful in hard-to-reach areas.
• Preparation: Before welding, ensure that the surfaces of the parent metal are thoroughly cleaned to achieve optimal results.
• Shielding Gas: Use pure argon or a mix of 95% argon and 5% CO2 for shielding.
