L301是含银10%的银钎料,价格较低,但熔点高、漫流性差,钎焊接头塑性也较差,因此应用不广。
L301 is a silver solder containing 10% silver. The price is low, but it has a high melting point, poor flowability, and poor plasticity of brazing joints, so it is not widely used.
主要用于钎焊铜及铜合金、钢及硬质合金。
Mainly used for brazing copper and copper alloys, steel and hard alloys.

1. 钎焊前必须严格清除钎焊处及钎料表面的油脂、氧化物等污物。
2. 钎焊时须配银钎焊熔剂共同使用,或使用涂敷有钎剂的钎料。
1. Before brazing, the grease, oxides and other dirt on the brazing part and the surface of the solder must be strictly removed.
2. When brazing, it must be used together with silver brazing flux, or use brazing filler metal coated with flux.
