Tungsten Carbide Material

What Is Tungsten Carbide Material?

Tungsten carbide material is a hard composite made from tungsten carbide particles bonded with cobalt, nickel, or other metallic binders. It is one of the most widely used tool materials in industry, valued for its extreme hardness, wear resistance, and strength.

Renyuan Mould supplies a full range of tungsten carbide materials in the form of rods, plates, blocks, tubes, blanks, and custom preforms for tool and die manufacturing.

Properties of Tungsten Carbide

Tungsten carbide offers hardness from 86 to 93 HRA, high compressive strength, excellent wear resistance, and good corrosion resistance. It is roughly three times stiffer than steel and denser than lead. The material retains its hardness at elevated temperatures.

These properties make tungsten carbide ideal for cutting tools, drawing dies, wear parts, and high-pressure applications.

Available Forms

We supply tungsten carbide rods, round bars, plates, sheets, blocks, tubes, rings, nozzles, and custom blanks. Standard sizes are available from stock, and custom dimensions can be produced to order.

Materials can be supplied as-sintered, semi-finished, or precision ground to customer drawings.

Carbide Grades

Our carbide grades include fine-grain grades for finishing and precision applications, medium-grain grades for general use, and coarse-grain grades for impact-resistant applications. Cobalt content ranges from 6% to 15% depending on hardness and toughness requirements.

Special grades such as nickel-bonded corrosion-resistant and titanium-containing grades are also available.

Manufacturing Process

Tungsten carbide is produced by milling tungsten carbide powder with binder metal, pressing into blanks, and sintering in vacuum furnaces at temperatures above 1400 degrees Celsius. The resulting material is then ground to final dimensions.

Applications

Tungsten carbide material is used to make cutting tools, drawing dies, stamping dies, punches, nozzles, wear parts, sealing components, and precision gauges. It is essential in automotive, aerospace, metalworking, mining, and oil and gas industries.

Quality Control

Every batch of tungsten carbide material undergoes hardness testing, density measurement, grain size inspection, and dimensional verification. Material certifications are available on request.

Custom Solutions

Renyuan Mould can produce custom carbide blanks and preforms based on customer drawings or samples. We assist with grade selection and geometry optimization to reduce machining costs and improve material utilization.
