大正磷铜焊条-圆

The application of phosphor bronze welding rodsSuitable for the welding of copper and copper pipe joints in the refrigeration systems of air conditioners, refrigerators, and freezers.

1、 BCu92P：Composition P: 7.5-8.5%, Copper: Bal. Melting temperature: 710-750°C. Low melting point, good fluidity, but relatively brittle. Generally used for brazing without impact loads and vibration-free copper and brass parts.

2、BCu93P（HL201/BCuP-2）：成分 P：6.80-7.50%，铜：余量。熔化温度，该焊料流动性好，可以流入间隙很小的接头，但钎料脆，一般用于机电和仪表工业，钎焊不受冲击载荷的铜和黄铜零件；

3、BCu89SnP（HL208）：Composition: P: 6.80-7.50%, Tin: 5.0-6.0%, Copper: Balance. Melting temperature: 620-660°C. This solder has a low melting point and good fluidity, which can be brazed with silver flux for copper, brass, bronze, and low-zinc brass parts.

4、BCu86SnP：Composition P: 4.80-5.80%, Tin: 7.00-8.00%, Nickel: 0.40-1.20%, Copper: Bal. Melting temperature: 620-670°C. The solder has the same application as above. The addition of nickel increases the brittleness, but improves the fluidity and results in a bright weld. It is generally used for brazing of copper and brass.

5、BCu91AgP（HL209/BCuP-6）：成分 P：5.50-7.50%，银1.80-2.20%，铜：余量。熔化温度645-771℃，熔点低，该焊料能在较大温度范围内填充接头间隙，多用于电冰箱、空调器、电机和仪表行等业钎焊铜及黄铜件；

6、BCu89AgP（BCuP-3）：成分 P：5.8-6.70%，银4.80-5.20%，铜：余量。熔化温度645-788℃，熔点低，该焊料延性和导电性得到提高，流动性一般，适宜于钎焊间隙较大的铜及黄铜零件；

7、BCu88AgP（HL205/BCuP-7）：成分 P：6.50-7.00%，银4.80-5.20%，铜：余量。熔化温度645-780℃，熔点低，该焊料延性和导电性得到提高，流动性好于B-Cu89PAg，一般用于钎焊间隙较大的铜及黄铜零件；

8、BCu87PAg（BCuP-4）：成分 P：7.0-7.5%，银5.80-6.20%，铜：余量。熔化温度645-718℃，熔点低，该焊料熔点低，流动性很好，能钎焊间隙较小的接头，一般用于铜及黄铜部件的钎焊；

9、BCu80PAg（HL204/BCuP-5）：成分 P：4.80-5.30%，银14.50-15.50%，铜：余量。熔化温度645-815℃，熔点低，该焊料的延性和导电性得到进一步的改善，用于焊接要求比HL205（5%银）钎料高且接头间隙较大的铜及黄铜零件。

10、BCu60ZnSn-R (S221/RBCuZn-A): Composition: Copper: 59.00-61.00%, Tin: 0.80-1.20%, Silicon: 0.15-0.35%, Zinc: Balanced. Melting temperature: 890-905°C. This solder has a relatively high melting point and can be used for welding hard alloy tools, molds, and mining tools. It can also replace H62 solder to obtain a more dense weld seam, and can be used as a welding wire for gas welding brass.
