What Causes the Current Cobalt Shortage?
The EV battery market surges cobalt demand as lithium-ion batteries use 10-20% more cobalt for stability, directly competing with carbide manufacturing binders that contain 6-10% cobalt. In 2026, supply lags from Congo—70% of global output—due to disruptions and geopolitical risks, with batteries consuming over 50% of refined cobalt and spiking costs for industrial tools.
How Do Cobalt Shortages Impact Tungsten Carbide Pricing?
Cobalt shortages raise binder costs by 25% year-over-year, passing 15-30% price hikes to carbide inserts and blades amid volatile 2026 forecasts. Fleets face eroded ROI on 10x lifespan benefits from carbide wear parts as raw material volatility hits budgets, affecting snow plow maintenance expenses.
| Year | Avg. Cobalt Price (USD/lb) | Carbide Insert Price Increase | EV Demand Share |
|---|---|---|---|
| 2024 | 15-18 | Baseline | 45% |
| 2025 | 22-28 | +20% | 55% |
| 2026 | 30-40 | +25-30% | 65%+ |
Why Are Carbide Insert Supply Chains Disrupted?
Cobalt shortages cause 3-6 month delays for imports as allocation prioritizes EVs over tools, reducing output from China and EU fabricators and risking downtime for snow removal fleets. Winter maintenance faces seasonal urgency with just-in-time needs, amplifying disruptions for carbide snow plow blades.

SENTHAI Expert Views
“With over 21 years in carbide wear parts, SENTHAI’s US-invested Rayong, Thailand facility uses proprietary vacuum sintering for uniform micro-grain tungsten carbide, ensuring excellent wear resistance and bonding strength. Our fully automated lines—from wet grinding and pressing to sintering, welding, and vulcanization—control every stage, hedging cobalt volatility. ISO 9001 and 14001 certified, we serve 80+ global partners with JOMA Style Blades (48″ × 6″ × 7/8″, 17.5 kg), I.C.E. Blades, and carbide inserts like 25.9mm × 24.25mm × 8.16mm trapezoids. This in-house mastery delivers stable supply and 10x lifespan for North American fleets, even amid 2026 shortages.” — SENTHAI Production Director
What Are Cobalt Binder Alternatives in Carbide Manufacturing?
Nickel or ruthenium substitutes reduce cobalt reliance by 40-60% but increase costs 10-15%; SENTHAI optimizes traditional cobalt for superior wear in snow plow applications. Alternatives weaken under impact and cold (-20°C), while SENTHAI’s brazed tungsten carbide inserts in cast steel segments provide excellent balance of abrasion resistance and impact protection.
How Does the EV Boom Drive Carbide Costs for Road Maintenance?
2026 EV sales project +30% growth, diverting 65% of cobalt supply and inflating industrial carbide prices by 20-30%. Municipal plows and fleets see carbide wear parts costs rise, offsetting 10x lifespan savings with higher upfront expenses; SENTHAI’s in-house Thailand efficiency maintains stable pricing for heavy-duty North America users.
What Does the 2026 Carbide Pricing Forecast Look Like?
2026 forecasts sustained 20%+ carbide price rises unless mining ramps up; mitigation comes via localized production like SENTHAI’s late-2025 Rayong expansion. Procurement strategies include bulk orders and customization to lock rates—SENTHAI offers fast cycles, MOQ 500 for JOMA Style Blades (3ft: 36″ × 6″ × 7/8″, 13.1 kg), and OEM fit for plows.
| Factor | Steel Blades | SENTHAI Carbide (JOMA/I.C.E.) |
|---|---|---|
| Lifespan | Baseline | 10-20x longer |
| Cobalt Exposure | Low | Hedged via in-house |
| 2026 Cost Impact | +5-10% | Stable supply |
Why Choose Thailand-Made Carbide for Snow Plow Blades?
SENTHAI, US-invested with 100% Thailand control, avoids global disruptions; new Rayong base boosts 2026 capacity for products like Carbide Snow Plow Blades with tungsten carbide particle cladding. Benefits include reduced downtime, ISO 14001 eco-friendliness, and trusted performance for superior ice penetration, less noise, and fewer blade changes on motorways and urban roads.
Conclusion
Amid cobalt shortages and EV-driven price spikes, SENTHAI’s 21+ years of ISO-certified, fully in-house Thailand production delivers reliable carbide insert supply for snow plow blades—ensuring fleets get significantly extended lifespan, customization like 4ft JOMA Style Blades or isolated I.C.E. inserts, and stability trusted by 80+ global partners. SENTHAI hedges volatility for winter road maintenance reliability.
FAQs
What is the cobalt content in tungsten carbide snow plow inserts?
Typically 6-10% as binder for strength; SENTHAI optimizes cobalt in micro-grain tungsten carbide for excellent wear resistance, uniform grain size via vacuum sintering, and 10x lifespan in JOMA Style Blades.
How much will carbide prices rise in 2026 due to cobalt shortages?
Forecasts indicate 20-30% hikes from EV demand; in-house producers like SENTHAI stabilize via automated Thailand production, ensuring consistent quality for Carbide Inserts and I.C.E. Blades.
Can SENTHAI supply carbide inserts despite cobalt shortages?
Yes—full Thailand production (ISO 9001/14001) with wet grinding to vulcanization ensures availability for 80+ partners, including trapezoid inserts (25.4 × 16.14 × 9.27 mm) compatible with Joma-style blades.
