Abstract

A cemented carbides, base on the tungsten carbides (WC), are very popular and useful in an industry. The most important metal which is using as a binder in this kind of materials is cobalt. It has many advantages as a binder: very good wettability, favorable solubility with WC and thermal conduction similar to WC. However, costs of cobalt is very height because natural resources aren’t sufficient. Cobalt isn’t also neutral for health it is known as an allergen and same research shown that it could cause a cancer. This paper presents results of sintering the tungsten carbides with Fe-Mn alloys as the binder.
