BCu58ZnFeSn(Si)(Mn) | 57-59 | REM | Sn: 0.7-1.0 Si: 0.05-0.15 Mn: 0.03-0.09 Fe: 0.35-1.2 | ≤0.15 | 865 | 890 | 900-930 |
Advantages
1. Wide range of applications
0%-20% silver content:brazing copper parts. Higher silver content also stainless steel-steels
2. High Joint Strength, No Deformation
Increase silver content can improve strength,lower melting point to protect the base metal
3. Good electrical conductivity
high joint strength, good plasticity, and good electrical conductivity
