摘要： A dense cemented carbide product is described. The product is manufactured from WC with a grain size between 0.1 and 0.4 &mgr;m, fine grain size cobalt and ruthenium powders. The product is used in PCB machining operations where the addition of 10-25% Ru to the binder phase offers up to 25% wear resistant increases and up to 100% increase in chipping resistance in PCB routing compared to conventional materials (6% cobalt and 0.4 &mgr;m grain size).

摘要： A metal matrix composite casting comprises a metal matrix composite and a processed member inserted in the metal matrix composite by enveloped casting. By the processed member which is easier to process than the metal matrix composite, a processed portion of a predetermined shape can be formed in the metal matrix composite. That is, by a simple processing such that the processed member is removed from the metal matrix composite or the processed portion is formed in the processed member itself, the processed portion having a desired shape can be easily formed in the metal matrix composite.
