Ready-to-Press Grade Powders

Discover More

Ready-to-Press tungsten carbide grade powders are free flowing powders ready to use as starting materials in the production of cemented carbide tools, wear parts, and other precision components. Since the 1970’s, GTP has designed and manufactured hundreds of custom grades international customers. In our powder grades, we use inhibitors such as VC, CrC, MoC, TaC, TaNbC, NbC, or TiC with cobalt, nickel, and iron binders. Different variations ranging from micro-grain to ultra-coarse straight grades to complex alloy grades are manufactured regularly. Because each powder grade is different, it is critical that there is a strong link between the powder manufacturer and the parts fabricator. GTP has the experience and expertise to provide that link. Our team is dedicated to developing a powder that meets your specific requirements.

Critical Characteristics of Cemented Tungsten Carbide

Wear Resistance / Hardness

Ability of one material to wear, abrade, deform, or indent another material.

Compressive Strength

A measure of a material’s ability to withstand compressive forces, where it is squeezed laterally.

Impact Strength

Measure of a material’s ability to withstand mechanical shock.

Transverse Rupture strength

Stress required to break a specimen; used to evaluate mechanical strength.

Tribological Properties

Dealing with interacting surfaces in relative motion, a process leading to wear.

Specific Weight / Density

A means of quality control, cemented WC approaches theoretical density when sintered.

Magnetic Properties

Magnetic saturation & coercivity are measures of how well cemented carbides have been sintered.

Modulus of Elasticity / Rigidity

A measure of how a material or structure will deform and strain when placed under stress.

Thermal Shock Resistance

Measure of a materials ability to withstand major temperature changes without cracking.

Corrosion Resistance

Resistance to the interaction between oxygen molecules and the substances it interacts with.

Security of Supply

Global Tungsten & Powders has exclusive supply agreements and an ownership stake in mines throughout the world. We are certified by the Conflict-Free Sourcing Initiative (CFSI) as a conflict free smelter, meaning we do not source from any conflict regions. From ore concentrate we produce APT, tungsten oxide, tungsten powder, and tungsten carbide in-house. Additionally, we have the capability to produce APT from secondary raw materials.
