We use Tungsten Carbide every day in a variety of products, for use in a number of different applications throughout many industries. It is an incredibly versatile and useful material due to its unique properties
There are over a dozen different grades of Tungsten Carbide. When evaluating or finding equivalents of Tungsten Carbide grades the important criteria is to specify two of three factors; binder content, hardness or grain size.
When choosing between the numerous distinct grades, it is important to understand what properties are required for the application. For example grade CD-630 is extremely hard wearing, but only able to cope with low impact, so it is perfect blades and seal rings. Whereas CD-70 is designed to endure high impact environments and is therefore perfect for manufacturing header dies.
The Tungsten Carbide properties chart, on our website, shows basic data for each grade manufactured. All specifications are designed and engineered for a purpose and rigid controls are kept throughout production processes to ensure adherence to grade engineering.
Quality control properties such as hardness, density, and minimum transverse rupture strength were determined from tests made on each batch of powder before it is used in the manufacturing process. Other properties such as Young's modulus of Elasticity, Poisson's ratio, Coefficient of Thermal Expansion, Thermal Conductivity and Electrical Conductivity are used by engineers for design calculations. Properties such as compressive strength, grain size and abrasion resistance give the designer additional information about the suitability of the grade for the part being designed
