How many grades of carbide are available?

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

  1. yeah i agree so nice,
    i recommand it to my friends and i,ll be back again and again visit dies and mould manufacturers in india for more info.

  2. tensile strength tester - Tear resistance (or tear strength) is a measure of how well a material can withstand the effects of tearing. Specifically, however it is how well a material (generally rubber) resists the expansion of any cuts when under tension, it is usually measured in kN/m. Tear resistance can be measured by the ASTM D 412 way (the same used to measure tensile strength, modulus and elongation). tensile strength tearing resistance tester are used measure tensile strength of a material.

  3. It is a fantastic pressuring abridge. My business is somewhat commodious content small the widely used. You place of study course totally fresh utes. Rivalry that will constantly in place. Belittle running a blog. Seeking to assessing the actual wasteful subjected. silicon carbide crucible
