1, BCu92P: composition P: 7.5-8.5%, copper: allowance. Melting temperature 710-750℃, low melting point, the solder fluidity is good, but relatively brittle, generally used for brazing without impact load, vibration of copper and brass parts welding;

2, BCu93P (HL201/ BCUP-2) : composition P: 6.80-7.50%, copper: allowance. Melting temperature 710-793℃, the solder fluidity is good, can flow into the joint with small gap, but the solder is brittle, generally used in mechanical and electrical and instrument industry, brazing copper and brass parts without impact load;

3, BCu89SnP (HL208) : composition P: 6.80-7.50%, tin: 5.0-6.0%, copper: allowance. The melting temperature is 620-660℃. The solder has low melting point and good fluidity. It can braze copper, brass, bronze and low zinc brass parts with silver brazing agent.

4, BCu86SnP: composition P: 4.80-5.80%, tin: 7.00-8.00%, nickel: 0.40-1.20%, copper: allowance. Melting temperature 620-670℃, the use of the solder is the same as above, the addition of nickel makes brittleness increase, but the fluidity is improved, and the weld is bright, generally used for copper and brass brazing.

5, BCu91AgP (HL209/ BCUP-6) : Composition P: 5.50-7.50%, silver 1.80-2.20%, copper: allowance.
