Tungsten Carbide Strips

Description Of Tungsten Carbide Strips

Tungsten Carbide Strips are high-performance flat-shaped products manufactured from tungsten carbide (WC) with a metallic binder such as cobalt (Co), nickel (Ni), or molybdenum (Mo) through powder metallurgy and HIP (Hot Isostatic Pressing) sintering processes. These strips combine the extreme hardness of tungsten carbide with the toughness provided by the metallic binder, creating a composite material that excels in demanding wear and cutting applications.

The manufacturing process begins with high-purity tungsten carbide powder mixed with cobalt or nickel binder, followed by ball milling, pressing into strip blanks, and vacuum sintering at high temperatures. HIP sintering ensures a uniform, dense microstructure with minimal porosity, delivering superior mechanical properties.

Tungsten carbide strips offer exceptional performance characteristics that far surpass conventional tool steels. With hardness values ranging from HRA 86.5 to 92 — more than ten times harder than mild steel (approximately HV 160 vs. HV 1600) — these strips maintain their cutting edges and wear surfaces under extreme abrasive conditions. The combination of high hardness, wear resistance (10–50 times that of steel), and good impact toughness makes them the material of choice for a wide range of industrial applications.

Tungsten carbide strips are available in a wide range of dimensions, grades, and surface finishes to meet diverse application requirements across woodworking, mining, construction, metallurgy, and other industries.

Features Of Tungsten Carbide Strips

Extreme Hardness: Tungsten carbide strips offer hardness of HRA 86.5 to 92, far surpassing tool steel. With a Vickers hardness of up to 1600 HV, they are more than ten times harder than mild steel (approximately 160 HV), ensuring superior wear resistance and extended service life.

Excellent Wear Resistance: The wear resistance of tungsten carbide strips is 10 to 50 times that of steel. In high-wear applications such as woodworking, mining, and crushing, this translates to significantly longer tool life and reduced downtime.

High Strength and Toughness: Transverse rupture strength (TRS) typically ranges from 1800 to 3000+ N/mm², providing the strength needed to withstand impact forces and prevent premature fracture. Grades with higher cobalt content offer improved toughness for impact-resistant applications.

HIP Sintering for Superior Quality: HIP (Hot Isostatic Pressing) sintering produces strips with uniform microstructure, minimal porosity, and superior mechanical properties, ensuring consistent quality and performance.

High Density: With density ranging from 14.0 to 15.2 g/cm³, tungsten carbide strips provide excellent mass and stability in high-speed applications.

Excellent Heat and Corrosion Resistance: Tungsten carbide strips offer superior heat stability, anti-deformation at high temperatures, fine thermal shock resistance, high thermal conductivity, and good corrosion resistance against chemicals, acids, and alkalis.

Multiple Grade Options: Available in various grades including YG6, YG6X, YG8, YG10X, YG15, YG20C, K10, K20, K30, and custom compositions to suit different applications.

Customizable Dimensions: Available in a wide range of sizes with length up to 900mm, width up to 550mm, and thickness up to 140mm. Custom dimensions and shapes (flat bars, bars with arc, etc.) are available upon request.

Multiple Surface Finishes: Available in blank (unground), ground, and polished finishes to meet specific application requirements.

100% Raw Material Quality: Manufactured from 100% virgin raw materials to ensure consistent quality and performance.

Standard Compliance: Manufactured in accordance with ISO 9001:2008 quality standards.
