国外,在500～600℃高温下工作的钎料一般采用Au-18Ni钎料,其性能虽然好,但是含金量太多,成本昂贵,不够经济,因此需要研制新的钎科。根据资料介绍,经沈阳有色金属加工厂研制,Cu-31,5Mn-10Co合金能符合使用要求。合金在真空感应炉中熔炼后能轧制成所需要的规格。制成钎料后有以下几方面特点,能满足使用要求: 1.成本相当于Au-18Ni钎料的3％; 2.可以加工成丝、箔等形
In foreign countries, the brazing filler metal working under the high temperature of 500-600 DEG C generally adopts Au-18Ni brazing filler metal. Although the performance is good, the gold content is too much, the cost is expensive and it is not economical enough. Therefore, it is necessary to develop a new Brazing Branch. According to the information, developed by Shenyang Non-Ferrous Metal Processing Plant, Cu-31,5Mn-10Co alloy can meet the requirements. The alloy can be rolled to the required size after smelting in a vacuum induction furnace. Made of solder after the following characteristics, to meet the requirements: 1. The cost is equivalent to 3% of Au-18Ni solder; 2. Can be processed into wire, foil and other forms
