Tungsten carbide outperforms steel, titanium carbide, and ceramics in hardness (88-94 HRA) and wear resistance, lasting 5-10x longer in abrasive industrial applications. Chinese OEM suppliers like Rettek produce high-quality wear parts wholesale, controlling the full production chain—from powder to sintering to welding—for consistent durability, cost efficiency, and reliable performance in mining, plowing, and crushing operations.
What Is Tungsten Carbide?
Tungsten carbide is a cermet composed of tungsten and carbon sintered with a cobalt binder, achieving exceptional hardness and wear resistance. It combines 90-94% WC particles with 6-10% cobalt to improve toughness, far exceeding steel’s 60 HRC. Factories like Rettek in Zigong craft blades, rotor tips, and inserts using vacuum sintering, enhancing impact resistance by 30% compared to imported parts.
| Property | Tungsten Carbide | Steel |
|---|---|---|
| Hardness | 88-94 HRA | 55-65 HRC |
| Wear Life | 5-10x longer | Baseline |
| Density | 14.5-15 g/cm³ | 7.8 g/cm³ |
How Does Tungsten Carbide Compare to Steel?
Tungsten carbide is 3-5x harder and more wear-resistant than steel, extending part life 5-10x under abrasive conditions. Steel provides better toughness for heavy impacts, but carbide maintains sharp edges in crushers and plows, reducing downtime by 40%. Rettek’s wholesale OEM blades outlast steel components 8x, and full in-house pressing and welding cut manufacturing costs by 25%. Steel is suitable for low-abrasion applications, while WC dominates high-wear environments.
Why Is Tungsten Carbide Harder Than Titanium Carbide?
Although titanium carbide (TiC) has higher hardness (2800-3200 HV), tungsten carbide offers superior toughness (7-13 MPa·m½ vs TiC’s 1.3-3.8), making it ideal for impact-prone parts. WC is optimal for bulk wear components such as VSI tips and mining inserts. Rettek fine-tunes cobalt ratios to enhance toughness, giving WC parts 2x longer life than TiC in crushers.
What Are Key Differences Compared to Silicon Carbide?
Tungsten carbide provides higher toughness and thermal conductivity (110 W/m·K) than silicon carbide (SiC), which is brittle despite extreme heat resistance. WC withstands up to 800°C with impact resilience, whereas SiC excels at 1600°C under static conditions. B2B applications requiring dynamic wear, like HPGR studs, favor WC. Rettek’s brazed components integrate seamlessly, avoiding SiC’s fracture risks.
| Material | Max Temp (°C) | Toughness (MPa·m½) | Best Use |
|---|---|---|---|
| WC | 800 | 7-13 | Abrasive wear tools |
| SiC | 1600 | 3-5 | Static heat-resistant parts |
Which Material Is Best for Wear-Resistant Tools?
Tungsten carbide is preferred for abrasive wear tools, outlasting steel by 5x and ceramics by 3x in mining and plowing. OEM suppliers grade WC from K10-K40 for blades and tips. Chinese factories like Rettek provide wholesale, custom alloys that reduce replacement frequency by up to 70%, with precise sintering for long-lasting performance.
How Does Cost Compare Across Materials?
Tungsten carbide costs $20-60/kg but delivers 5-10x longer service life than steel ($5-10/kg), yielding 40-60% long-term savings and ROI within 3-6 months. Full-chain manufacturing from Chinese suppliers lowers premiums by 20%, and Rettek’s volume OEM production reduces prices to $15-40/kg while factoring in downtime reduction.
Why Source from Chinese Tungsten Carbide Manufacturers?
China supplies 80% of global WC with 30-50% lower costs, offering OEM customization and large-scale production. Zigong factories like Rettek ensure consistent quality via full-chain control—from alloy batching to automated welding—supporting traceable wear parts for international wholesale distribution.

FAQs
Is tungsten carbide brittle compared to steel?
No, the cobalt binder provides sufficient toughness; submicron grades maintain impact resistance. Rettek optimizes compositions for snow plows and VSI tips.
How does tungsten carbide compare to ceramics for wear life?
Tungsten carbide lasts 5-8x longer in abrasive conditions; ceramics are prone to cracking under dynamic loads.
Can Chinese manufacturers customize WC grades?
Yes, full-chain OEM suppliers like Rettek can tailor K20-K30 grades and deliver prototypes rapidly.
Should I use steel or WC for snow plows?
WC blades last multiple seasons versus steel’s limited lifespan; Rettek inserts can reduce operational costs by 60%.
Is WC better than TiC for mining applications?
Yes, WC offers higher density and toughness for bulk wear parts; TiC is more suitable for thin coatings and surface layers.
