马口铁空罐电阻焊焊轮是我国进D全自动制花生产线上关键的易报备件。长期以来，主要依靠进口，其价格昂贵，满足不了用户所需．CUNICoBe合金是我院为此而研制成功的一种电极合金．通过热处理而获得其优良的综合性能（硬度及导电率），所制焊轮自1992年应用于进口全自动制罐生产
Tin cans resistance welding welding tank is an automatic D flowers in China into the key production line easy to report spare parts. For a long time, mainly rely on imports, its expensive, can not meet the needs of users. CUNICoBe alloy is a kind of electrode alloy successfully developed for this purpose. Through the heat treatment to obtain its excellent overall performance (hardness and conductivity), the welding wheel since 1992, applied to the import of automatic canning production
