Abstract

本发明涉及一种钎焊硬质合金的锰白铜浸积合金。该合金除由Cu、Ni、Mn、Si之外，还加入了适量的B，经熔炼均匀熔合，铸锭，再进行压力加工，或者经熔炼后直接喷制成所需的形态。由于加进了B组之，使合金的可加工性及强度、溶透性、浸润性大大加强，缩短了钎焊时间，降低生产成本。

Description

锰白铜浸积合金
本发明涉及一种用于钎焊硬质合金的锰白铜浸积合金。
现有钎焊硬质合金的浸积合金主要是由铜、锰、镍和硅组合面成。这种合金晶粒粗，硬而脆，强度不够高，可加工性差，难以加工成所需形态，如薄片等，其溶透性、浸润性和粘结性都不理想。在钎焊硬质合金时流动性差，造成成品率低，产品强度、硬度和粘结性无法得到可靠稳定的保证。因此，采用这种合金钎焊硬质合金，不仅生产不稳定，同时也降低了产品的质量。
本发明的目的在于提供一种浸积合金，既能改善产品的可加工性，又使产品强度、浸润性和粘结性大大提高。
本发明浸积合金除由Cu、Ni、Mn、Si四种元素组成之外，还加进了B元素，其中Cu、Ni、Ma、Si和B在合金中所占的重量百分比为：Cu 42.000～70.000，Ni 8.000～27.000，Mn 9.000～31.000，Si 0.090～2.700，B 0.008～0.190。生成浸积合金的方法是：将以上组元，经过溶炼均匀溶合，铸成铸锭，再进行压力加工，或者经溶炼后直接喷制成所需的形态，如块状、片状、条状、颗粒状和粉未状等。
由于本发明采用B(硼)组元：①使合金晶粒细化度提高，从而提高其可加工性和材料的强度；②提高了合金在熔化状态下的流动性，从而提高合金的溶透性和浸润性；③由于改变了合金的形态，提高了溶透性，从而缩短了钎焊时间；④由于B组元具有较强的脱氧能力和保护作用，从而提高了合金铸造质量和钎焊质量。因此跟现有技术产品比较，本发明浸积合金不仅质量有明显提高，而且其利用率高出五分之二，大大降低了成本，提高经济效益。
在本发明的具体实施例中，各种组份的重量百分比如表一。表1：
Figure C9611915500041
本发明的最佳实施例，各组分在合金中所占重量百分比是：Cu 60.000、Ni 19.804、Mn 19.866、Si 0.300、B 0.030。
