Depending on the end product there are many grades of carbide to choose from. Each of the grades has its own set of properties and characteristics which makes it suited to specific uses. Our management team has many years of experience and will be happy to offer practical guidance on the development and applications of Tungsten Carbide.
Our long-established network of suppliers guarantees that the highest quality raw materials are used for our powder grades, all of which are traceable to the source and are non-conflict certified.
You can find our grade list here – you may find it useful to read-through our brief guide below:
Finding the Appropriate Grade
- Ultra-fine grain carbides are characterised by a very high hardness and wear resistance.
They are used for milling tools and drills for processing abrasive, soft and tough materials, in nozzles and in wear protection parts.
WC grain size | super-sub-micron, 0.6 – 0.7μm
- Submicron grain carbides are homogeneous, fine microstructure of this grade allows for high hardness and cutting abilities and is excellently suited for machining and milling tools, drills, guides, cutting tools, pressing dies, in wear protection and even for fine punching tools.
WC grain size | sub-micron, 0.7 – 0.9μm
- Fine grain carbides are the standard in general wear protection. They are used for guides, bushings, nozzles, slide rings, cutting rings, linear blades, circular blades, lathe tips, reshaping, rolling, drawing and pressing tools.
WC grain size | fine, 1.0μm
- These carbide grades with medium grain size combine good hardness and wear resistance with high transverse rupture strength, fracture toughness and thermal shock resistance. Application in general wear protection, for guides, bushings, slide rings, cutting rings, blades, lathe tips, reshaping, rolling, drawing and pressing tools.
WC grain size | medium, 1.7 – 4.0μm
- The coarse grain grades have higher fracture toughness and thermal shock resistance in comparison to the finer grades with the same cobalt content. They are therefore well suited against impact stress. A primary area of application is in mining/road construction.
WC grain size | coarse, 4.5 – 6.0μm
- Our nickel bonded carbide grade is highly corrosion-resistant and is better suited to working in more hostile environments such as with acids, for deep-sea applications and also within the medical industry.
WC grain size | submicron, 1.0 – 2.0μm
