Description of tungsten carbide strips / plates / blocks:

Tungsten carbide strips is a sintered metallurgical product of powder form. It is manufactured in vacuum or Hydrogen reduction furnace with refractory tungsten material (WC) micron powder as the main ingredient and Cobalt (Co), Nickel (Ni) or Molybdenum (Mo) as the binder.It has many excellent characteristics such as high hardness and strength, good wear and corrosion resistance and salient stability under high temperature (even at 500 ºC it is essentially unchanged and at 1000 ºC it is still of high hardness). We supply several types of tungsten carbide strips: strip with angle, round strip and cemented tungsten carbide strip.

Tungsten carbide strips widely known as one kind of carbide cutting tools, it's available for different grinding geometric parameters and suitable for both cutting materials and nonmetal materials, also it can be applied to conventional, carbide inserts semi-automatic lathe, automatic lathe and planning machine to work grooves and operate cutting

We are a professional tungsten carbide manufacturer in China over 16-year and have a few senior engineers who specialize in tungsten carbide field for many decades Recommended grade: YG6 (K10), YG6X YG8 (K20), YG15 (K30), we can research and develop more suitable formula according to use condition and processing characteristics for client. For your non-standard parts, we have strong ability to make mold by ourselves and produce them per your requirements

We have strict quality control and assurance system to guarantee the consistent quality

Features of Tungsten Carbide Strips:

Tungsten carbide strip and sheet has the characteristics of high red-hardness, good weld ability, high hardness and good wear resistance, it is mainly used for machining the solid wood, density board, grey cast iron, non-ferrous metal materials, chilled cast iron, quenched steel, PCB, braking materials. When used, should according to the specific purpose to choose the right material of tungsten carbide strip and sheet.

Cemented carbide strip blanks in variable dimensions with an overall length of 310 /320mm. They are available in three standard profiles: rectangular, single bevel angle , or double bevel angle .we can cut into different length as customer request ,the surface can be blanks or mirror finished ,if you have special design on carbide strips ,we can produce according to your drawing .base on different application ,our technical team will recommend suitable carbide grade for you .

Application of carbide strips :

BENEFITS OF TUNGSTEN CARBIDE IN TOOLING

Strength – Tungsten carbide has very high strength for a material and is extremely hard and rigid. Compressive strength is higher than almost all melted, cast, forged metals and alloys.

Rigidity – Tungsten carbide compositions range from (2) to (3) times as rigid as steel and (4) to (6) times as rigid as cast iron and brass. Young’s Modulus is up to 94,800,000 psi.

Heat Resistance – Tungsten Carbide is highly resistance to deformation and deflection and is very valuable in applications where a combination of minimum deflection and good ultimate strength is the first consideration.

Impact Resistant – For such a hard material with very high rigidity, the impact resistance is high.

Heat and oxidation resistance – Tungsten-base carbides perform well up to about 1000°F in oxidizing atmospheres and to 1500°F in non-oxidizing atmospheres

Low temperature resistance (cryogenic properties) – Tungsten carbide retains toughness and impact strength in the cryogenic temperature ranges. (-453°F.)

Thermal Conductivity – Tungsten carbide is in the range of twice that of tool steel and carbon steel.

Electrical Conductivity – Tungsten carbide is in the range equal to that of tool steel and carbon steel.

Specified Heat – Tungsten carbide ranges from about 50% to 70% as high as carbon steel.

Weight – The specific gravity of tungsten carbide is from 1-1/2 to 2 times that of carbon steel.

Hot Hardness – When temperature increases to 1400°F, tungsten carbide retains much of its room temperature hardness. At 1400°F, some grades equal the hardness of steels at room temperature.

Tolerances – Many surfaces or even complete parts can be used the way they come from the furnace, “as sintered”, such as mining or drilling compacts. In those parts requiring precision ground accuracy, such as stamping dies, close-tolerance preforms are provided for grinding or EDM.

Methods of Fastening – Tungsten carbide can be fastened to other materials by brazing, epoxy cementing or mechanical means. Tungsten carbide’s low thermal expansion rate must be carefully considered when preforms are provided for grinding or EDM.

Coefficient of Friction – Tungsten carbide compositions exhibit low dry coefficient of friction values as compared to steels.

Galling – Tungsten carbide compositions have exceptional resistance to galling and welding at the surface.

Corrosion-Wear Resistance – Specific grades are available with corrosion resistance approaching that of noble metals. Conventional grades have sufficient resistance to corrosion-wear conditions for many applications.

Wear-Resistance – Tungsten carbide wears up to 100 times longer than steel in conditions including abrasion, erosion and galling. Wear-resistance of tungsten carbide is better than that of wear-resistance tool steels.

Surface Finishes – Finish of an as-sintered part will be about 50 micro inches. Surface, cylindrical or internal grinding with diamond wheel will produce 18 micro inches or better and can produce as low as 4 to 8 micro inches. Diamond lapping and honing can produce 2 micro inches and with polishing as low as 1/2 micro inch.
