Sifmig No 8 Phosphor Bronze MIG Brazing Wire – 0.8 mm x 4 Kg

Description

Sifmig No 8 Phosphor Bronze MIG Brazing Wire – 0.8 mm x 4 Kg

Sifmig No 8 is a phosphor bronze MIG brazing wire, primarily composed of copper and enriched with 7% tin. This wire is specifically designed for fusion welding of phosphor bronze castings, copper alloys, and brass. Additionally, it’s versatile enough to be used for MIG brazing on a variety of metals including ferrous, stainless, and dissimilar metals. One of its notable applications is to provide a wear-resistant layer on surfaces prone to abrasion.

Key Features:

• Phosphor Bronze Composition: Contains 7% tin, making it suitable for welding phosphor bronze castings and copper alloys.
• Versatility: Can be used for MIG brazing on various metals and for applying a bearing surface.
• Wear Resistance: Ideal for providing a wear-resistant layer on surfaces prone to abrasion.

Typical Applications:

• Fusion Welding: Suitable for phosphor bronze castings, copper alloys, and brass.
• MIG Brazing: Can be used on ferrous, stainless, and dissimilar metals.
• Surface Layering: Used to apply a wear-resistant layer on surfaces subject to abrasion.
• Crack Repair: Effective for repairing cracks in castings.

For parent metals containing trace amounts of lead (e.g., LG2), it’s recommended to apply SIFMIG 8 in stages. Between each pass, grinding is advised to remove lead that might have been drawn into the joint, thereby reducing porosity.
