Description

一种用于铜质散热器硬钎焊的银铜钎料
技术领域
本发明涉及一种铜硬钎焊钎料，尤其是一种用于铜质散热器硬钎焊的银铜钎料。
背景技术
铜硬钎焊技术的应用范围很广，可生产用于客车、卡车和工程机械的散热器、暖风机、机油冷却器、中冷器、冷凝器和蒸发器等。然而，与传统软锡焊工艺相比，铜硬钎焊工艺需要能在600℃以上的高温下仍能保持良好的强度和热性能的新型高强度钎料。使用这种材料，设计人员可以设计出强度高且更薄更小的散热器，从而减轻散热器重量，降低成本。
发明内容
本发明旨在解决上述问题，提供了一种用于铜质散热器硬钎焊的银铜钎料，它熔点低，流动性好，在高温下仍能保持良好的强度和热性能，是一种理想的铜基硬钎焊钎料，其采用的技术方案如下：
一种用于铜质散热器硬钎焊的银铜钎料，其特征在于：所述的银铜钎料组成成分包括：Cu、Ag、P、Ni，其各组成成分按重量百分比依次为：Ag1.5-2.0%，P7.0-7.5%，Ni0.4-0.8%，Cu余量；所述钎料熔化温度范围在620～750℃之间，属铜硬钎焊用低温硬钎料；所述Ag能与Cu形成固溶体，既能增强接头的强度，又能降低钎料的熔点；所述Ni的加入，会提高钎料的流动性，但Ni也会与Cu形成脆化相，从而使脆性增大；所述P会与Cu固溶结合，提高焊缝的强度。
本发明具有如下优点：它熔点低，流动性好，具有良好的润湿性和铺展性能，能在较大温度范围内填充接头间隙，而且其焊缝细、牢固，质量可靠，还具有良好的力学性能和机械性能，配合银钎剂可以钎焊铜及黄铜散热器，也可用于电冰箱、空调器、电机和仪表行业钎焊铜及黄铜，是一种性能优良、用途较广的用于铜质散热器硬钎焊的银铜钎料。
具体实施方式
下面结合实例对本发明作进一步说明：
一种用于铜质散热器硬钎焊的银铜钎料，其特征在于：所述的银铜钎料组成成分包括：Cu、Ag、P、Ni，其各组成成分按重量百分比依次为：Ag1.5-2.0%，P7.0-7.5%，Ni0.4-0.8%，Cu余量；所述钎料熔化温度范围在620～750℃之间，属铜硬钎焊用低温硬钎料；所述Ag能与Cu形成固溶体，既能增强接头的强度，又能降低钎料的熔点；所述Ni的加入，会提高钎料的流动性，但Ni也会与Cu形成脆化相，从而使脆性增大；所述P会与Cu固溶结合，提高焊缝的强度。
上面以举例方式对本发明进行了说明，但本发明不限于上述具体实施例，凡基于本发明所做的任何改动或变型均属于本发明要求保护的范围。
