-
-
Superior Load-Bearing Capacity
-
High transverse rupture strength (≥2000 MPa) withstands heavy冲击 and vibration.
-
-
Corrosion & Heat Resistance
-
Performs reliably in temperatures up to 1000°C and harsh chemical environments (acids, alkalis).
-
-
Customizable Design
-
Available in standard and custom shapes (cylindrical, tapered, threaded) to fit specific machinery.
-
Common Applications of Tungsten Carbide Pegs
Tungsten carbide pegs are versatile solutions across industries requiring extreme wear resistance:
1. Mining and Mineral Processing
-
Crusher Rotor Pins: Anchor hammer tips in rock crushers, enduring constant abrasion from granite and ores.
-
Screening Equipment Pegs: Secure mesh panels in vibrating screens, resisting impact from falling rocks.
2. Oil and Gas Drilling
-
Drill Bit Retainers: Lock cutting inserts in place for deep-well drilling tools.
-
Valve Components: Serve as wear-resistant guides in high-pressure control systems.
3. Construction and Demolition
-
Pile Driver Guides: Reinforce alignment systems for foundation piling machinery.
-
Concrete Cutting Blades: Act as pivot pins in diamond blade assemblies.
4. Aerospace and Defense
-
Rotor Shaft Bushings: Reduce wear in helicopter rotor systems.
-
Armor Component Fasteners: Provide lightweight, durable fastening for armored vehicles.
5. Agriculture and Forestry
-
Harvester Blade Pins: Secure cutting blades in combine harvesters.
-
Wood Chipper Axles: Withstand abrasive wear from tree bark and debris.

Frequently Asked Questions (FAQ)
Q1: How do tungsten carbide pegs compare to ceramic alternatives?
-
Tungsten Carbide: Higher toughness, better impact resistance, and easier machining.
-
Ceramics: More brittle but excel in ultra-high-temperature non-impact environments.
Q2: Can these pegs be repaired if damaged?
-
Yes! Damaged pegs can often be reground or recoated, depending on wear extent.
Q3: What mounting methods are recommended?
-
Press-Fit: For permanent installations in high-vibration systems.
-
Bolted: Use high-strength threaded inserts for replaceable components.
Q4: Are they suitable for marine environments?
-
Yes! Cobalt-bonded grades resist saltwater corrosion, but nickel-bonded variants (e.g., YN6) offer enhanced protection.
Industry Case Study: Extending Crusher Rotor Lifespan
Challenge: A copper mine’s hammer crusher rotor pins wore out every 2 weeks, causing frequent downtime.
Solution: Custom YG10 tungsten carbide pegs with tapered ends for secure hammer retention.
Result: Peg lifespan increased to 6 months, reducing maintenance costs by 65%.
