It has fluidity and is suitable for serving. Although it is inferior to the Bcup-2 and Bcup-3 types, it is a well-balanced wax material.
For copper / copper alloy bonding
Length (mm) 500 Melting Point (℃) 640~788 JIS Standard BCup-6 Material Copper: 91%, Phosphorus: 7%, Silver: 2%
It has excellent fluidity and penetrates into narrow spaces just before joints. No flux is required for copper brazing. The brazed part has good airtightness, low temperature strength, and electrical conductivity. It is much more economical and has the same effect as silver wax. Suitable for braz... Read More
