No. 0 high phosphorus copper electrode
High phosphorus copper filler metal
Alias: Material 201(L201)
Conforms to GB BCu93P-A
Equivalent to AWS BCuP-2
Description:
No. 0 high phosphorus copper electrode is close to eutectic composition of copper-phosphorus binary filler metal, low melting point, with good fluidity, can flow into the gap is very small. The price of brazing metal is cheap, so it is widely used. However, the plasticity of the brazed joint is poor, and the joint in the impact and vibration working state should not be used.
Application:
Widely used in motor, instrument and refrigeration industry brazing copper and copper alloy.

Note:
1. Before brazing, grease, oxide and other dirt must be strictly removed from the brazing site and the surface of the brazing filler metal.
2. No brazing flux is required when brazing copper, but silver flux should be used when brazing copper alloy.
We will use professional export fumigation-free wood, according to the actual number of products customized wooden boxes, wooden trays, etc. It should be noted that different products have different packaging, the specific model and specifications to determine, of course, we are very willing to package according to customer requirements. The transportation mode is mainly sea and land transportation, and the specific need to negotiate with the customer to determine.
