Tungsten Carbide Round Rod

Tungsten carbide round rod has been ground to achieve the precise shape and size, and has a precision tolerance. The tungsten carbide round rod provides high wear resistance, and good corrosion and heat resistance. Tensile strength, used to indicate the material's overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Hardness describes its resistance to permanent surface deformation.

Tungsten carbide round rod is mainly applied in making drills, end mills and reamers. And it is also used for cutting, punching and measuring tools. It is used in the industries of paper making, package, printing, non-ferrous metal processing. Also, it is widely used processed as HSS cutting tool, carbide end mills, carbide cutting tool, NAS Cutting tool, Aerospace cutting tool, carbide drill, milling cutter core drill, high speed steel, taperd end mills, metric end mills, miniature end mills, pilot reamer, electronics cutter, step drill, double margin drill, metal cutting saw, gun barrel, angle milling cutter, carbide burrs, carbide tipped cutter etc.

The grade of YG6, YG6X, YG8 is better wear resistant than Mk6, it can used for hard wood, processing original wood aluminum section bar, brass rod and cast iron, etc. The grade of YG10 is wear and percussion resistance, used for processing hard wood, soft wood ferrous and non-ferrous.

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. This material was developed for use in cutting tools, having hard ceramic crystals of a few microns in size within a ductile metal matrix. The resulting material 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 rod not only can be used as cutting and drilling tools(such as micron drills, twiste-drills, vertical mining cutter index able file)also can be used as 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 Mandrel

Tungsten carbide mandrel is a smaller version of the mandrel, the mandrel standard carbide overall length always are less than 100mm, the main length is 80mm. But if the customers have special required about the size, we could provide the mandrel according to different customer requirements. Tungsten carbide mandrel is mainly used in the pressing direction of the mandrel in the compact or the sintered body forming mold parts Profile.

Application

Ordinary materials of mandrel are mainly for the production of seamless pipe when inserted into the body with the interior annular grooved rolls or the like so that the pipe forming tool. Continuous rolling machine rolling, pipe rolling ramp extended period type rolling machine rolling, you must use a mandrel head pipe and tube when cold-rolled cold drawn.
Tungsten carbide mandrel, as special nature of the material, and carbide materials prices are relatively high, so it is usually used in the main oil bearing plants, metallurgy plants, tool factory and relatively high-end products.

Features
1. Mirror-polished, surface finish to Ra0.02μm.
2. The outer diameter of the precision required to achieve 0.001mm, roundness to within 0.5μ.
3. Size can be made according to customer specified to make a variety of specifications; the minimum outside diameter can be processed Φ0.2mm size.
4. Tungsten carbide mandrel is characterized by material wear, very suitable for oil-bearing plants, metallurgy plants, and tool factory.

Tungsten Carbide EDM Electrode

Main material for tungsten carbide EDM electrode is copper, iron and tungsten copper alloy, these electrode material with their own characteristics, can be used for different occasions. Copper is the most common for electrode material,which can be manufacture more complex electrode tool under cold extrusion processing. Tungsten copper with the best heat resistance, which is the best material for electrode tools, but it with high costs and highest unit price. In the early iron is widely used as tungsten carbide EDM electrode during the period of thyratron pulse power, and now is continue to use the EDM pulse power transistor for some mold makers. The three electrode materials used in tungsten carbide EDM electrode with the completely different wear characteristics. Find out the processing rules of tungsten carbide EDM electrode, which is able to provide some date under developing special carbide machining pulse power. Also with some practical significance on the development of EDM technology and improving the mold machining accuracy.

Through the experimental study for copper, tungsten copper and iron in tungsten carbide EDM electrodes, we could find the following results.

1、Polarity was be greater impact on the electrode wear, different material should choose different polarity, the tungsten copper is suitable as negative electrode.
2、Under the small pulse width, Since the protective film is not easy to promote, it is difficult to achieve low loss electrode.
3、Processing current will large affect electrode weariness, it will with different trends under the changed of processing current for different material. Electrode wear is falling for tungsten copper under the increased current, and copper will be increased.

Tungsten Carbide Pen Ball

In the 1970s, tungsten carbide pen ball started to develop our country, after small batch, always adopt a stainless steel ball pen with beads as the situation was broken. Tungsten carbide pen ball with properties of good wear resistance, corrosion resistance, and reduce the production cost of the manufacturing process of continuous improvement, it is rapidly spread.

Carbide ball for oily pen, and corrosion resistant carbide beads used for water-based formulations, gel pen, it is currently written materials most used and most reliable materials, ball diameter size, determines the thickness of the line handwriting. WC-TiC-Cr3C2 composite carbide solid solution has high hardness, high wear resistance, high corrosion resistance, etc., and low price, than the amount of beads (spherical beads with the quality ratio of the composite powder produced) than WC -Co carbide ball is manufactured (WTiCr) C-Co (Ni) series of pen-based materials with the best carbide ball beads. Such composite materials successfully resolved during sintering beads micropores and unstable mass of black heart problems (presence of holes on a photomicrograph of the beads), the beads greatly improve production yield.

Tungsten Carbide Pen Ball
