　　产品说明：

　　1 铜锌钎料

　　1.1 使用说明

　　铜锌钎料可采用浸渍钎焊、感应钎焊、气体火焰钎焊、炉中钎焊等工艺方法，钎焊前须对母材表面进行清除氧化膜、油脂、尘物处理，并充分预热。

　　感应钎焊时，钎料和钎剂要在装配前安置好，切忌使钎料呈封闭环，防止钎料本身产生感应电流而过早熔化产生虚焊、缺焊。

　　盐浴浸沾钎焊应定期对盐浴液脱氧并予以调整成分。

　　Copper base braze welding material

　　1 Cu-Zn braze welding material

　　1.1 Guideline

　　Cu-Zn braze welding material HL105 and HL801 have good invasion property, extensibility property, shear strength property of joint and strength of extension. They can be used for braze welding of cemented carbide tools, drilling bits and bits. These bits can get long working life, better impact load and fatigue load.

　　Cu-Zn braze welding materials can use techniques such as dip brazing, induction brazing, flame brazing and furnace brazing, the matrix should be clean up and pre-heating before welding.

　　Braze welding materials and brazing flux should in place before induction brazing, the braze welding materials must avoid closed hoop in case of generate inductive current to cause quality problems.

　　Salt-bath brazing techinque should deoxidize the salt liquid and make ajustment for composition.
