Description

Sifmig 985 MIG Copper Brazing Wire – 0.8 mm x 4 Kg

The Sifmig 985 is a premium MIG brazing wire primarily composed of a minimum of 98.5% copper, enriched with deoxidizing elements. This wire is specifically designed for MIG welding of copper, offering resistance to high temperatures and corrosion. Its composition ensures a strong and durable weld, making it ideal for joint welding of high-oxygen copper joints and materials.

Key Features:

  • High Copper Content: Contains a minimum of 98.5% copper, ensuring a robust and durable weld.
  • Deoxidizing Elements: Enhances the quality of the weld by preventing oxidation.

Typical Applications:

The Sifmig 985 MIG Copper Brazing Wire is primarily used for:

  • MIG Welding of Copper: Ideal for creating strong and durable joints in copper materials.
  • High-Oxygen Copper Joints: Perfect for joint welding of high-oxygen copper joints and materials.
  • Thick Materials: If the material thickness exceeds 6mm, it’s recommended to pre-heat the component to a temperature between 600ºC and control the cooling post-welding to ensure a slow and gradual reduction in heat.

Material to be Welded

Used in MIG welding of copper, this wire is ideal for joint welding of high-oxygen copper joints and materials. If material thickness is >6mm, pre-heat component 600ºC< – control cooling after welding to ensure slow, gradual reduction in heat.

For optimal results, it’s essential to ensure that the areas to be welded are clean and free from contaminants. Proper pre-heating and controlled cooling techniques should be employed, especially when working with thicker materials.
