Copper-Based Brazing Materials
Product Description
The nano-crystalline copper-based brazing sheets are labeled as MCNT2020 and MCNT2050. They belong to the copper-phosphorus series of copper-based brazing materials.
Product Advantages
Uniform composition, high purity, no component separation, significantly improves the strength of brazed joints. The brazing sheets are foil-shaped, allowing precise material control and suitable for brazing large-area workpieces. The joint strength for copper and copper alloys can reach 98-137 MPa.

Widely used in precision instruments, conductive contacts of electrical components, red copper parts, silver alloy parts, and large-area brazing surfaces of red copper radiators and heat exchangers. Can replace silver brazing sheets. Workpieces need to be degreased and derusted before brazing. Suitable for resistance brazing or furnace brazing.
