Description
Sifmig 8 MIG Brazing Wire – 1.0 mm x 12.5 Kg
The Sifmig 8 MIG Brazing Wire, with a diameter of 1.0mm and weighing 12.5 Kg, is a premium phosphor bronze wire enriched with 7% tin. It is specifically designed for fusion welding of phosphor bronze castings, copper alloys, and brass. Additionally, this wire is versatile enough to be used for MIG brazing on ferrous, stainless, and dissimilar metals, making it ideal for applying a bearing surface.
It’s a popular choice for welding bronze, brass, copper, and copper alloys, especially in applications that require crack repair in castings or the addition of a wear-resistant layer on surfaces prone to abrasion. When working with metals that contain trace amounts of lead, such as LG2, it’s recommended to apply the SIFMIG 8 in stages, grinding between passes to eliminate lead from the joint and minimize porosity.
Key Features:
- Phosphor Bronze Composition: Contains 7% tin, making it suitable for fusion welding of specific metals.
- Versatility: Can be used for MIG brazing on a variety of metals, including ferrous, stainless, and dissimilar metals.
- Wear-Resistance: Ideal for adding a wear-resistant layer on surfaces that are subject to abrasion.
Typical Applications:
The Sifmig 8 MIG Brazing Wire is commonly used in:
- Metal Repair: Especially useful for crack repair in bronze, brass, and copper castings.
- Surface Enhancement: Applying a wear-resistant layer on surfaces prone to abrasion.
- General Welding: Fusion welding of phosphor bronze castings, copper alloys, and brass.
- Bearing Surfaces: Used for MIG brazing to apply a bearing surface on various metals.
- Specialized Welding: For metals containing trace amounts of lead, ensuring optimal weld quality and minimal porosity.
