With the rapid economic development, national defense, transportation and other industries are gradually increasing their demand for high-performance anti-shock non-sag tungsten wire (not easy to sag and difficult algorithm of fault). How to prepare the production process based on the common non-sag tungsten wire process on high temperature with good non-sag properties and anti-shock performance? Non-sag tungsten powder metallurgy preparation stage has a critical effect on the temperature and anti-shock resistance of tungsten wire:

At a temperature of 260 ~ 460 ℃, and hydrogen flow rate is 0.3 ~ 0.5m3 / h , using ammonium paratungstate(APT) (with good flow properties , impurity content of less than 50ppm, grain morphology of monoclinic hexagonal structure) to obtain a tungsten blue oxide with a particle size of 9.1μm in restore conditions.

At 550 ~ 870 ℃, adding K, Si, Al, Co elements to tungsten blue oxide, through a two-stage reduction, obtained tungsten powders of different particle size, think that B: D powder is 4: 6 ratio of the tungsten powder with a particle size normal distribution, the most beneficial to get a good high temperature non-sag tungsten wire properties and seismic performance.

Tungsten Carbide Square Rod Application

Tungsten carbide square rod has good red hardness, high hardness, high wear resistance, high pressure resistance, high oxidation resistance, low coefficient of expansion, fine electric and heat conduction. Due to all these advantages, it is widely used in many industries like wood industry, electrical industry, metal industry and other industries where high hardness and high wear resistance is required.

Tungsten carbide square rod application includes cutting and drilling tools (such as micron drills, twist-drills, vertical mining cutter index able file), typing needles, rollers various wear parts and structural materials. Besides, it can be extensively used in many fields, such as mechanical, chemical, petroleum, metallurgical, electronic and national defense industry. Tungsten carbide square bar has a high resistance to thermal shock, so is able to withstand the rapid temperature fluctuations. Also, this has found a use as electrodes for Electrode Discharge Machining (EDM).

Tungsten Carbide Square Rod

Tungsten carbide square rod is a shape for square, and it is a kind of rod. Tungsten carbide square rod is a hard, brittle ceramic which, when combined with 6% to 10% Cobalt, forms a tough cermet. Tungsten carbide square rod can withstand the high compressive stresses imposed during cutting, as well as having good wear and oxidation resistance at the high temperatures reached. Tungsten carbide square bar has a high resistance to thermal shock, so is able to withstand the rapid temperature fluctuations. Also, this has found a use as electrodes for Electrode Discharge Machining (EDM).

Tungsten carbide square rods are available in a wide selection of micro-grain and sub-micron grades that are engineered to stand up to thermal extremes, vibration, and impact wear. The tungsten carbide square rod that can be ground to h6 tolerances a variety of grades that provide exceptional wear and impact resistance grades for use in end mills, reamers, drills, countersinks, engraving tools, routers, and other rotary tools.
