Tungsten Carbide Machined Parts for High Precision Industrial Applications
Product Overview
Tungsten Carbide Machined parts, commonly known as tungsten carbide or simply carbide, is a composite material consisting of hard carbide particles (primarily tungsten carbide, WC) bonded together by a metallic binder (usually cobalt, Co).
This combination results in cutting tools that are exceptionally hard, wear-resistant, and capable of operating at high temperatures and speeds, making them the industry standard for most metal cutting applications.
In industrial manufacturing, Cemented Carbide Parts (often called "Hard Metal") are high-performance components engineered for environments where steel would fail.
They are metal matrix composites consisting of hard carbide grains (usually Tungsten Carbide) "cemented" together by a metallic binder (usually Cobalt).
Key Physical Properties
Extreme Hardness: It ranks between 9 and 9.5 on the Mohs scale, just below diamond. This makes it incredibly resistant to wear and deformation.
High Density: It is significantly heavier than steel, providing stability in high-speed applications.
Thermal Stability: It maintains its hardness even at temperatures up to 700°C to 1000°C, where high-speed steel would soften.
Compression Strength: It has a very high resistance to being crushed, though it is more brittle than steel when subjected to heavy impacts.
Application Categories
Part Category | Specific Examples | Why Carbide? |
Cutting Tools | CNC Inserts, End mills, Drill bits, Saw blades | Stays sharp longer than steel; allows for faster cutting speeds. |
Wear Parts | Nozzles, Seals, Bushings, Valvetrains | Resists erosion from high-pressure fluids or abrasive slurries. |
Mining/Drilling | Rock bits, DTH buttons, Road milling teeth | Can crush through granite and concrete without wearing down. |
Forming Dies | Wire drawing dies, Cold heading dies | Holds precise dimensions under massive pressure. |
