Product Overview
This is a tungsten carbide nozzle designed for use in 3D printers. It is made from a high-density WC-Co composite with nickel and iron additives. The nozzle is pressed and sintered to maintain dimensional stability and high hardness. It is suitable for continuous extrusion of abrasive or high-temperature filaments. It is available in standard sizes or customised to drawing.
Key Benefits
- High hardness and wear resistance extend nozzle life in abrasive filament printing
- High thermal conductivity dissipates heat quickly, reducing thermal stress
- Small coefficient of thermal expansion maintains tight tolerances during thermal cycling
- High density (16.5–18.5 g/cm³) improves structural integrity and resistance to deformation
- Good electrical conductivity and weldability allow for integration into custom tooling systems

Problems It Solves
- Standard metal nozzles wear out quickly when printing with abrasive filaments, leading to clogging and inconsistent extrusion
- Thermal expansion in metal nozzles causes dimensional drift during printing, affecting print accuracy
- Low thermal conductivity in standard nozzles leads to heat build-up and filament degradation
- Frequent nozzle replacement increases downtime and production cost
- Lack of custom internal geometry in off-the-shelf nozzles limits performance in specialised printing tasks
Who It Is For
- 3D printing hardware brands integrating high-performance nozzles into their systems
- Industrial and aerospace manufacturers using high-temperature or abrasive filaments
- Machinery and tool makers producing custom 3D printing components
- R&D labs testing new filament materials under high-wear conditions
- Manufacturers of multi-material 3D printers needing durable, long-life nozzles
Application Scenarios
- Continuous printing with carbon fibre or glass-filled filaments that abrade standard metal nozzles
- High-temperature printing with engineering thermoplastics like PEEK or PEI
- Industrial 3D printing lines requiring minimal downtime due to nozzle failure
- Prototyping and production environments where consistent print quality is critical
- Custom 3D printing setups requiring a nozzle with specific internal geometry
Technical Features
- Pressed and sintered from high-purity tungsten carbide with nickel and iron additives
- High density (16.5–18.5 g/cm³) ensures minimal porosity and structural strength
- High tensile strength (700–1000 MPa) resists mechanical failure under pressure
- Small coefficient of thermal expansion (1/2 to 1/3 of iron or steel) maintains dimensional stability
- High thermal conductivity (5 times that of steel) improves heat distribution
- High hardness (84–93 HRA) resists wear from abrasive materials
- Good electrical conductivity and workability allow for integration with custom systems
Materials and Grades
- Tungsten carbide matrix with 97% WC, 2.1% Ni, 0.9% Fe for enhanced sintering and wear resistance
- High-purity tungsten raw materials used in production
- Nickel and iron additives improve densification and mechanical strength
- Grade YG6X selected for balance of hardness and toughness in high-wear applications
Customisation Options
- Manufactured to customer drawings including non-standard and specially shaped nozzles
- Internal geometry and outer diameter adjusted to match specific printer requirements
- Grade changed to suit filament type and operating temperature
- Samples produced for pre-testing before bulk release
How This Part Is Made
Drawing review and material selection
Powder blending with high-purity WC, Ni, and Fe
Pressing on imported press for consistent green density
Over-pressure sintering to achieve high density and closed porosity
Grinding to final dimensions and internal geometry
Dimensional and physical property inspection
Packing and shipping
Quality Control
- Physical properties, shape and tolerance are checked before shipping
- Every order is tested before bulk production is released
- Inspection photographs of the finished order are sent for confirmation before delivery
Use Guide
- Send the filament type, operating temperature, and required nozzle geometry for grade and size selection
- Use a sample to test extrusion consistency and wear resistance before bulk order
- Avoid sudden temperature changes; allow the nozzle to equalise before starting print
- Clean the nozzle regularly to prevent filament residue build-up in the throat
- Keep one sample from the first batch for comparison when measuring wear in future orders
How It Compares With The Alternatives
| Alternative | Trade-off |
|---|---|
| Steel nozzle | Steel is cheaper and easier to machine but wears rapidly with abrasive filaments, leading to clogging and inconsistent print quality |
| Ceramic nozzle | Ceramic has higher hardness but is brittle and prone to cracking under thermal or mechanical shock; carbide tolerates thermal cycling better |
| Standard tungsten carbide nozzle | This version has added nickel and iron for improved sintering and strength; standard grades may not achieve the same density or toughness |
