Top-Quality welding wire Supplier
Product description
Silver-copper-phosphorus based brazing alloys are designed to braze copper to copper and copper to brass.The phosphorus in these alloys act as a fluxing agent thus these alloys do not require a brazing flux when used to braze copper to copper. The silver in these alloys influence fluidity and improves the overall ductility of the brazing alloy. Silver-copper-phosphorus brazing alloys include a wide variety of compositions and melting temperature ranges and can be heated in many different ways.
WIRE COMPOSITION (%)
| Trade Mark | chemical composition | Melting temperature℃ | Main characteristics | application | ||
| Ag% | Cu% | Zn% | ||||
| BAg10CuZn | 9-11 | 52-54 | 36-38 | 815-850 | Cheap price, high melting point, poor immersion, poor joint plasticity. | Suitable for steel, copper alloy, stainless steel, etc. where brazing is not required. |
| BAg20CuZn | 19-21 | 40-42 | 38-40 | 690-810 | The melting point is slightly higher, the immersion property and the joint plasticity are improved. | Suitable for steel, copper alloy, stainless steel, etc. where brazing is not required. |
