1. What is Spherical Tungsten Carbide-Cobalt Powder?

Spherical WC-Co Powder is a composite powder consisting of hard tungsten carbide particles held together by a cobalt binder. It is engineered to provide a combination of extreme hardness, wear resistance, and toughness.

2. Why is cobalt added to tungsten carbide?

Cobalt acts as a metallic binder that improves the toughness, ductility, impact resistance, and adhesion of the tungsten carbide coating while maintaining excellent hardness.

3. What WC-Co compositions are available?

Common compositions include:

• WC-5Co
• WC-6Co
• WC-8Co
• WC-10Co
• WC-12Co
• WC-15Co
• WC-17Co
• WC-20Co

Custom WC/Co ratios are available.

4. What applications use WC-Co Powder?

WC-Co powder is widely used for:

• HVOF thermal spray
• HVAF thermal spray
• Wear-resistant coatings
• Hardfacing
• Mining equipment
• Oil & gas equipment
• Aerospace components
• Industrial machinery

5. What particle sizes are available?

REG Metals supplies WC-Co powder in several particle size ranges, including:

• 5–15 µm
• 10–30 µm
• 15–45 µm
• 20–53 µm

Custom particle size distributions are available.

6. What is the advantage of spherical WC-Co powder?

Spherical morphology provides improved:

• Powder flowability
• Feeding consistency
• Packing density
• Spray efficiency
• Coating uniformity

These characteristics are especially important for thermal spray systems.
