We are a manufacture of ferro alloy in China. We produce ferro molybdenu, Mo Oxide and also ferro tungsten.

ferro tungsten is mainly used as the alloy addition in steeling making.

1. Properties: tungsten is one of the important alloy elements which are used to make special steel. While tungsten reduce a little elongation rate of steel, it raises strength limit and yield point and also raises hardness and abrasion resistance of steel. It is very important that tungsten has good influence on high temperature mechanical properties of steel to improve heat resistance and tempering stability of steel.
