Tungsten Carbide Dies

Tungsten carbide die has a performance between the tools and construction materials between ceramics and high-speed steel, has a overall performance of high hardness, high strength, high density, corrosion resistance, high temperature oxidation resistance and low coefficient of expansion. Its life expectancy is ten times or even several times over steel.

Tungsten carbide dies usually refers to all kinds of wire drawing die, there are pull-mode optical fiber drawing. The center of all the drawing die hole has a certain shape, round, square, octagonal or other special shapes. Metal is pulled through the die hole size smaller, or even shape change.

Advantages of tungsten carbide dies
1.tungsten carbide with high hardness, high wear resistance and high red hardness, at 550 ℃ still maintain more than 56HRC hardness;
2.Has a high modulus of elasticity, generally is (4 ~ 7) × 104kg / mm2, and excellent rigidity at room temperature;
3.Have a high compressive strengthwhich is greater than 6000MPa;
4.Have good resistance to oxidation and corrosion resistance, acid resistance, alkali resistance and high temperature not easily oxidized;
5.Has a low coefficient of thermal expansion, suitable for manufacturing high ,precision, sharp die.

Tungsten carbide dies have a wide range of uses, such as electronic devices, radar, television, instrumentation, and aerospace and other high-precision wire and commonly used tungsten wire, molybdenum wire, stainless steel wire, alloy wire and cable wire. A variety of diamond wire drawing dies are pulled out for use. Diamond wire drawing die use natural diamond used as the raw material, which has strong wear resistance, high service life.
