What is a tungsten carbide button?

Tungsten carbide buttons deliver exceptional performance across industries. In mining, they act as drill bit cutting edges to penetrate hard rock. For roadwork, they shred asphalt/concrete in milling cutters, resisting heavy abrasion. In oil/gas exploration, their impact resistance stabilizes downhole tools under extreme pressure/temperature.

Manufactured via powder metallurgy: tungsten carbide powder is mixed with a cobalt binder in precise ratios, pressed into button – shaped preforms, then sintered at high temps to fuse particles. Final precision grinding/lapping ensures dimensional accuracy and smooth surfaces.

Thanks to superior properties, these buttons are critical for mining drill bits, road milling machines, oil/gas drilling tools, and even high – precision parts like valve seats—enabling reliable operation in harsh conditions.

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 You Need to Know About Common Nozzle Parameters

In mining, road construction, and precision machining industries, the performance of tungsten carbide buttons directly affects operation efficiency, tool lifespan, and processing quality.

I. Basic Material Parameters

Alloy Grade: Such as YG6, YG8 (with different cobalt contents, affecting hardness and toughness), YG6X (fine-grained, with better wear resistance), etc. For mining, choose high toughness (such as YG8); for precision machining, fine-grained grades can be selected.
Tungsten Carbide Grain Size: Fine grains (0.6 – 1.0μm) have good wear resistance, and ultra-coarse grains (> 6.0μm) have strong impact resistance. Match the working conditions as needed (such as ultra-coarse grains for hard rock crushing, and fine grains for precision grinding).

II. Shape and Size Parameters

Shape and Code: Conical, wedge-shaped, mushroom-shaped, etc. (Codes are custom-defined by enterprises, such as “J for cylindrical, C for mushroom-shaped”), and should be adapted to the equipment (such as flat cutting teeth for coal miners, and conical teeth for drilling).
Diameter/Height: Such as “Φ13.44*13.2mm” (for cylindrical teeth). It needs to match the size of the equipment tool holder/drill bit; otherwise, it won’t fit!
Tolerance Requirements: Tolerances for tooth height, tooth top circular runout, etc. (such as ≤ 0.025mm), which affect the adaptation accuracy with the equipment. Large tolerances may easily lead to operation vibration and accelerated wear.

III. Mechanical Performance Parameters

Hardness (HRA/HV): HRA is generally 85 – 93, and HV is 1250 – 1400. High hardness means good wear resistance but high brittleness. For impact working conditions, choose a slightly lower hardness (to balance toughness).
Bending Strength: 75 – 250 kg/mm². The higher the cobalt content, the better the strength. For mining cutting teeth, high bending strength (to resist impact fracture) is selected.
Impact Toughness: Usually < 0.5 kg·m/cm². The toughness of coarse-grained alloys is better than that of fine-grained alloys. For scenarios with large vibration (such as crushers), priority is given to selection.

IV. Application Adaptation Parameters

Applicable Working Conditions: Stratum hardness (such as rotary drilling teeth are divided into economic type for 6 – 20MPa and hard rock type for 30 – 70MPa), equipment type (coal miner/roadheader/milling machine). Choosing the wrong one may easily cause tooth chipping and fast wear.
Temperature Adaptation: Conventional type < 350℃, and tungsten carbide strengthened type < 450℃. For high-temperature working conditions (such as smelting furnaces), special heat-resistant coatings are required.

V. Process and Quality Parameters

Processing Precision: Such as 0.002mm (for precision ground teeth). For precision machining (such as PCB drills), the precision requirement is extremely high. Poor precision may affect the product qualification rate.
Coating Parameters (if any): Coating thickness (0.06 – 0.08mm), bonding strength (> 75MPa). Wear-resistant coatings can greatly prolong the service life. When selecting, ask about the coating process clearly.

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.
