Meeting the Demand for High-Performance Hard Alloy Components

Industries such as aerospace, oil & gas, mining, high-speed machining, and precision tooling require components made from ultra-durable materials like tungsten carbide and other hard alloys. These materials provide extreme hardness, wear resistance, and thermal stability, making them ideal for tooling, dies, nozzles, punches, bushings, and wear parts.

To ensure performance in harsh conditions, these components must meet high dimensional accuracy and exceptional geometric tolerances. We are a trusted CNC machining expert, delivering precision manufacturing solutions for carbide, tungsten steel, and hard alloy components.

Machining Challenges and Engineering Solutions

Hard alloy materials like tungsten carbide pose unique machining challenges due to their extreme hardness, brittleness, and low machinability. To meet these demands, we utilize advanced techniques such as EDM, precision grinding with diamond wheels, ultrasonic-assisted machining, and laser micro-machining.

We also implement cryogenic cooling, custom fixturing, and digital simulations to optimize tooling, reduce thermal distortion, and maintain tight tolerances. These solutions allow us to deliver consistent quality even on the most demanding projects.

Materials and Their Properties

• Tungsten Carbide (WC-Co): Ultra-hard, wear-resistant, and stable under high temperatures. Ideal for cutting tools and nozzles.
• Cemented Carbides (e.g., YG6, YG8, YL10.2): Balanced hardness and toughness depending on cobalt content and grain structure.
• Tungsten Steel: Highly resistant to pressure and heat, used in dies and punches.
• Other Hard Alloys: Including TiC and cermets, offering excellent thermal and corrosion resistance.

Advanced CNC Machining Capabilities

• Tolerances: Up to ±0.001 mm on critical dimensions
• Surface Finish: Ra ≤ 0.02 μm with precision grinding
• Size Range: Diameters 2–200 mm, lengths up to 800 mm
• Technologies: CNC turning/milling, cylindrical and surface grinding, EDM, laser and ultrasonic finishing
• Inspection: CMM, air gauges, roundness testers, surface profilometers

We ensure complete traceability and offer dimensional reports, material certificates, and process documentation upon request.

Common Applications and Machined Parts

• Oil & Gas: Valve seats, sleeves, nozzles, plugs
• Mining: Button bits, bushings, wear plates
• Tooling: Punches, dies, core pins
• Injection Molding: Gate bushings, inserts, cores
• Aerospace: Wear-resistant nozzles, fasteners
• Machinery: Rollers, guides, slide rails

All components are manufactured according to customer drawings or 3D models. Reverse engineering is also available.

Project Highlight: Carbide Valve Sleeve for Drilling Equipment

We produced a high-precision valve sleeve from YG8 cemented carbide, used in high-pressure drilling:

• OD Tolerance: ±0.002 mm
• Roundness: ≤ 0.0015 mm
• Surface Finish: Ra ≤ 0.02 μm
• Process: EDM, rough and precision grinding, lapping, air gauge verification

This part improved lifespan by 40% over previous steel designs and met all pressure and leakage performance tests.
