What is a tungsten carbide button?

Tungsten carbide alloy teeth are high-performance wear-resistant components with tungsten carbide as the hard phase and cobalt (or nickel/iron-based binders) as the matrix, compatible with various cutting and drilling equipment (such as mining shearers, roadheaders, and drill bits). With high hardness (HRA 85–93, HV 1250–1400), excellent wear resistance (up to 50 times that of ordinary steel), and balanced impact toughness (adjustable via cobalt content and grain size), they can stably operate under extreme conditions like high-impact loads, abrasive formations, and low-temperature environments. Their main functions include crushing rocks, shearing coal, and withstanding cyclic impact forces to assist equipment in excavation, tunneling, and material handling operations. They are core components in mining, construction, and energy exploration fields, widely used in scenarios such as coal mining (shearers), hard rock drilling (rock drills), and road milling (milling machines).

Common Nozzle Hole Structures

The type of tungsten carbide button determines key characteristics such as the penetration pattern, wear resistance, impact force distribution, and application suitability in different working conditions.

Tapered Button

Structural Feature

Presents a cone – like silhouette. The upper part tapers to a sharp tip, while the lower part connects to a cylindrical or slightly enlarged base. The smooth, tapered profile ensures a gradual force – application transition during operation.

Functional Advantage

Delivers concentrated penetration force at the tip, excelling in breaking hard, brittle materials (e.g., rock, concrete). The tapering shape also reduces friction during insertion/withdrawal, minimizing wear on both the button and the parent equipment.

Typical Applications

Mining & Quarrying: Drill bits for hard – rock blasting, rock – splitting tools.
Construction: Concrete demolition attachments (e.g., hydraulic breakers), pavement – breaking equipment.

Wedge - shaped Button

Structural Feature

Features a broad, flat “wedge” profile with two angled sides converging to a narrow edge. The base is wider than the tip, creating a distinct trapezoidal cross – section.

Functional Advantage

Generates high shearing/raking forces along the angled edges. Ideal for slicing through layered or abrasive materials, as the wide base distributes impact to reduce localized stress.

Typical Applications

Road Maintenance: Asphalt milling cutters, road – planing tools (shreds worn pavement).
Recycling: Scrap – metal shears, waste – concrete crushers (shears through rebar/mixed debris).

Coal Cutter Button

Structural Feature

Combines a robust, truncated – cone shape with reinforced wear zones. The tip is slightly rounded (to prevent excessive abrasion), and the body integrates flutes or ridges for debris evacuation.

Functional Advantage

Balances penetration (for coal seams) with abrasion resistance (against sandstone/dust). Flutes clear coal dust to prevent clogging, maintaining cutting efficiency in long – duration mining.

Typical Applications

Coal Mining: Shearers, roadheaders (cuts through coal seams, handles minor rock inclusions).
Underground Construction: Tunnel – boring machines (soft – rock excavation).

Flat - top Button

Structural Feature

Boasts a flat, circular or polygonal top surface atop a cylindrical or tapered base. The flat face provides a stable, broad contact area.

Functional Advantage

Delivers uniform, low – stress pressure over large surfaces. Reduces localized wear on both the button and the material being processed, ideal for precision or repetitive tasks.

Typical Applications

Machining: Abrasive – waterjet nozzles (stabilizes jet flow), precision grinding wheels (uniform abrasion).
Agriculture: Rotary tillers, seeder openers (smoothly cuts soil without excessive penetration).

Spoon - shaped Button

Structural Feature

Resembles a concave “spoon” profile: a curved, recessed tip merges into a wider base. The inner curve creates a scoop – like geometry.

Functional Advantage

Traps and carries loose materials (e.g., soil, gravel) during rotation. The curved surface also reduces material adhesion, preventing clogging in wet/dusty environments.

Typical Applications

Agriculture: Manure spreaders, compost turners (handles viscous, debris – laden materials).
Mining: Slurry – pump impellers, mineral – processing screens (transports fine particles).

Mushroom - shaped Button

Structural Feature

Has a domed, rounded “mushroom cap” top with a short, thick cylindrical base. The cap’s curvature is smooth and gradual.

Functional Advantage

Distributes impact forces over a wide area, minimizing damage to soft or brittle substrates. The rounded shape also reduces material buildup (e.g., sticky soils, adhesives).

Typical Applications

Forestry: Mulcher teeth (shreds vegetation without jamming).
Construction: Soft – soil compaction plates, asphalt – paver tamper bars (gentle yet durable pressing).

What Materials Are Commonly Used in Production?

Through the optimization of materials and processes, the service life of tungsten carbide nozzles under extreme working conditions can reach 5-10 times that of ordinary materials, making them core wear-resistant components in the petroleum, natural gas, and mining industries.

Table Instructions

Grade Adaptation Logic:
- For high-impact scenarios (mining/construction), prioritize high-cobalt grades (YG15+) or coarse-grained structures (e.g., YG8C), which offer superior fracture resistance.
- Precision mold applications require ultra-fine-grained alloys (YG3X), ensuring dimensional accuracy (<0.01mm tolerance) and surface finish (Ra≤0.8μm).
Special Industry Notes:
- In the oil & gas sector, YG10X-grade alloys often undergo surface treatment (e.g., diamond coating) to enhance resistance to sand erosion in downhole environments.
- Agricultural YG8 components typically feature a hardfacing layer (e.g., tungsten carbide particles) to extend service life in soil with high quartz content.
Material Selection Tips:
- When working with abrasive materials (e.g., concrete, quartz sand), choose alloys with ≥13% cobalt content (e.g., YG13) to balance wear resistance and impact resistance.
- For high-temperature applications (e.g., aerospace), YW series alloys (with TaC) outperform YG series in maintaining hardness at 600°C+ temperatures.
