Product Description

94% WC Tungsten Alloy Cement Grinding Balls Media Impact Resistance ODM

Achieving the Optimal Balance of Hardness and Impact Resistance

In industrial milling, grinding media selection critically impacts process efficiency and quality. For tungsten carbide-cobalt (WC-Co) composites, achieving the perfect balance between hardness and impact resistance is essential for optimal performance.

Key Factors in Grinding Media Selection

Material Composition: 94% tungsten carbide ensures superior hardness while 6% cobalt provides necessary ductility and toughness
Size and Shape: Spherical design enables efficient rolling and cascading actions during milling
Hardness and Density: Higher density media endure longer while maintaining milling efficiency
Cost-Effectiveness: Long operational lifespan reduces replacement frequency and maintenance costs

Mechanical & Physical Properties

Property	Tungsten Carbide (WC-6%Co)	Alumina (99%)	Zirconia (YTZP)	Steel (440C)
Density (g/cm³)	14.6-15.0	3.9	6.0	7.8
Hardness (HRA)	90-92	80-85	88-90	60-65
Fracture Toughness (MPa*m½)	10-12	4-5	7-10	15-20
Compressive Strength (GPa)	4.5-6.0	2.5	2.0	2.0

Key Takeaways:

2× Harder than alumina, 3× harder than steel - Minimal wear in abrasive environments
Highest density - Delivers superior kinetic energy for efficient grinding
Exceptional compressive strength - Withstands high-load milling operations

Wear & Durability Performance

Media Type	Relative Wear Rate	Lifespan (vs. Steel)	Cost Efficiency
Tungsten Carbide	1× (Benchmark)	20-50× longer	Best long-term
Zirconia	1.5-2×	10-15× longer	High upfront
Alumina	3-5×	5-8× longer	Moderate

Real-World Example: In cement ball mills, WC media lasts 2+ years vs. steel's 1-2 months.

Performance Summary: Why Choose Tungsten Carbide?

✅ Unmatched Hardness

✅ High Density

✅ Chemical Stability

✅ Longest Lifespan

Frequently Asked Questions

What is tungsten carbide grinding media?

Tungsten carbide grinding media consists of WC (tungsten carbide) particles bonded with cobalt (Co) or nickel (Ni). It is the hardest and most wear-resistant grinding material available, ideal for abrasive and high-impact milling.

What are the advantages over steel, alumina, or zirconia media?

Hardness (HRA 90+): 3× harder than steel, 2× harder than alumina
Density (14-15 g/cm³): Higher kinetic energy for faster grinding
Wear Resistance: Lasts 20-50× longer than steel in abrasive slurries
Contamination-Free: No iron/nickel leaching (critical for batteries, electronics)
