Extreme Hardness & Superior Impact Strength

Tungsten Carbide (WC) is an inorganic chemical compound containing equal parts of tungsten and carbon atoms. Colloquially referred to as cemented carbide, it is produced by sintering tungsten carbide powder with a binder metal—typically cobalt or nickel. This yields a material of exceptional density, extreme compressive strength, and high fracture toughness.

Micro Engineering manufactures custom-engineered Tungsten Carbide components designed to withstand severe mechanical wear, sliding friction, and heavy impact. Unlike harder but more brittle ceramics, our binder-optimized TC grades offer the ideal balance of high wear resistance and mechanical durability, preventing fracture failures in high-pressure oil/gas valves, slurry mixers, and mining tools.

Preferred for high-pressure seal faces, downhole drilling bearings, slurry pump sleeves, and heavy-impact industrial tooling.

Mechanical Properties

  • Hardness (HRA): 89.0 – 92.5
  • Density: 14.5 – 15.0 g/cm³
  • Binder Content: 6% – 12% (Co or Ni)
  • TRS Limit: 1800 – 2800 MPa
  • Compressive: 4000 – 6000 MPa

Features & Benefits

Cemented carbide components engineered to resist fracture, erosion, and friction.

Exceptional Toughness

High transverse rupture strength and fracture toughness. Resists chipping and structural cracking under high impact or shock loads.

High Density & Mass

Provides structural stability and high stiffness, minimizing deflection in high-pressure rotary seal operations.

Binder Material Versatility

Available with Cobalt binder for ultimate wear life, or Nickel binder (Ni) for enhanced corrosion resistance in acidic media.

Micro-Inch Surface Finish

Can be polished to optical mirror flatness (less than 1 light band), reducing friction and eliminating startup leakage.

Engineering & Performance Factors

Comparing Cobalt-Binder (Co) and Nickel-Binder (Ni) Tungsten Carbide grades.

Performance Parameters Cobalt-Binder TC (WC-Co) Nickel-Binder TC (WC-Ni)
Primary Characteristic Maximum hardness, ultimate wear and abrasion resistance. Corrosion resistance in acidic and caustic environments.
Corrosion Resistance Moderate (vulnerable to acidic fluids below pH 6). Excellent (highly stable in acidic and alkaline processes).
Fracture Toughness Extremely high (superior impact resistance). High (slightly lower than cobalt-bound grades).
Magnetism Highly magnetic. Non-magnetic or weakly magnetic.
Typical Applications Mining tools, heavy abrasive slurries, metal cutting dies. Acid pump seal faces, chemical valve trims, marine sleeves.
Lapping Capability Excellent mirror finish. Excellent mirror finish.

Why Choose Our Tungsten Carbide?

Micro Engineering manufactures custom cemented carbide wear parts with optimized binder systems for critical high-wear industrial applications.

Binder-Specific Engineering

We customize Cobalt or Nickel binder percentages (typically 6% to 12%) to balance wear resistance and chemical stability.

HIP Sintering Standards

Parts are processed through Hot Isostatic Pressing (HIP) to eliminate micro-porosities and ensure maximum density.

Helium Flatness Verification

Faces are polished and tested under monochromatic helium light to ensure flatness to within 1-2 light bands.

Micro-Ground Tolerances

CNC grinding tolerances are maintained to ±0.005mm, ensuring perfect alignment in cartridge seal stacks.
