Product Description
Overview
Carbide Tungsten Plate is a high-hardness sheet material manufactured through powder metallurgy processes such as pressing and sintering, using tungsten carbide (WC) powder bonded with metallic binders like cobalt (Co). Its hardness ranks just below diamond and cubic boron nitride, far surpassing ordinary steel. It finds extensive applications in manufacturing high-precision cutting tools for metal and wood, wear-resistant components, mining drilling tools, sealing rings, and similar products. As a non-ferrous metal products manufacturer with over two decades of specialised expertise, our company offers high-quality products, strong customisation capabilities, and reliable delivery performance.

- Strong chemical stability and corrosion resistance, suitable for diverse harsh environments, reducing maintenance costs.
- Low thermal expansion coefficient and low friction coefficient, ideal for applications requiring low wear and low energy consumption.
- Flexible machining properties enable the custom production of plates in various dimensions and performance specifications.
- High overall cost-effectiveness with extended service life, significantly enhancing production efficiency.
Application
1. Metal Cutting and Precision Machining
Carbide Tungsten Plate is employed in manufacturing turning/milling inserts, PCB micro-drills, deep-hole drills, threading tools, and similar components for machining challenging materials such as hardened steel, high-temperature alloys, and titanium alloys under high-speed cutting conditions. Tool life can be extended by 10 to 50 times compared to high-speed steel.
2. Mould Manufacturing
Employed in producing stamping dies, drawing dies, powder metallurgy moulds, hot-press sintering cores, etc. This reduces downtime for mould changes and enables mass production of silicon steel sheets, electronic components, and similar products.
3. Mining and Oil & Gas Extraction
Tunnel boring machine scrapers, down-the-hole hammers, petroleum screw drilling tools, wear-resistant liners, and valve plates for transfer pumps.
4. Aerospace and Defence
Aircraft engine blades, turbine disc thrust rings, rocket nozzle throat liners, missile guidance gyroscope bearings, tungsten carbide steel composite armour plates.
5. Semiconductor Processing
Punching dies for semiconductor packaging moulds, ensuring wafer edge integrity and meeting continuous production demands in cleanroom environments.
6. Medical Applications
Orthopaedic surgical positioning templates, dental drill cutting heads, MRI-compatible non-magnetic moulds, and other high-precision, high-cleanliness, and high-reliability medical or research environments.
What are the production processes of tungsten plates?
① Wet Mixing: Load tungsten carbide powder and binder powder into a ball mill at a predetermined ratio until the powder achieves uniform particle size and consistent composition distribution.
② Moulding: Fill the mixed powder evenly into custom steel moulds, ensuring close contact between particles and forming through compression.
③ High-Temperature Sintering: Subject the green compact to high-temperature heating, causing powder particles to diffuse, fuse, and densify, ultimately forming structurally compact, performance-stable carbide plates.
④ Precision Machining: Perform surface grinding and dimensional trimming on a lathe to ensure thickness tolerances remain within acceptable limits.
⑤ Surface Treatment: Apply polishing, honing, or coating processes to further enhance surface finish and performance characteristics.
