Tungsten copper metal injection molding (MIM) is a new type of powder forming technology, which also called powder injection molding (PIM), it is a method combines by powder metallurgy and injection molding.

Hydrothermal method produces tungsten trioxide using sodium dehydrate as raw material, by ultrasonic treatment and move to reaction still to produce tungsten trioxide.

Common seen tungstic acid producing method is tungsten concentrate soda sintering method, tungsten concentrate soda solution pressure digestion and sodium hydroxide solution decomposition method.

There are some influencing factors of thorium tungsten wire drawing.

1. The Blank State, including wire strength, cross-sectional size, cross-sectional shape, surface condition and consistency.

Tungsten electrode is pided into different types in accordance with the materials of tungsten, including pure tungsten electrode, lanthanated tungsten electrode, cerium tungsten electrode, thoriated tungsten electrode, yttrium tungsten electrode, zirconiated tungsten electrode, silver tungsten electrode and composite tungsten electrode. 

Tungsten heavy alloy has properties of high density, high tensile strength, good ductility, good ability to absorb radiation and good electrical performance and others.

Tungsten carbide seal is made from high-hardness refractory metal micron tungsten carbide powder as the main component and the binder of cobalt or nickel. Tungsten carbide seal is hard-surfaced materials with a large amount of friction material in the mechanical seal with good abrasion resistance, high flexural strength, high thermal conductivity and small expansion coefficient.

Many people want to know which weight of dart barrel is the most common one, and what's its average weight. Actually，there is no clear answer.

Sodium tungstate hydrothermal synthesis tungsten trioxide uses sodium tungstate dehydrate solution and sodium chloride as raw material in reaction still to produce tungsten trioxide.

Tungsten carbide button is an extremely hard alloy made from tungsten carbide and binders that offers high wear resistance as well as good corrosion resistance.
