Sintered Crushed Carbide is mostly used in Hardbanding operations.
By running a mild steel weld pool then feeding the crushed carbide via a feed hopper this give hardness and durability to any drill pipes, digger teeth, drag plates and shredders for the use in quarrying, excavating and recycling. Available in two grades: fused (fused tungsten carbide), or sintered (sintered tungsten Carbide) they have significantly different properties.
Fused Tungsten Carbide
This is the eutectic of tungsten and carbon. It has a very high hardness (typically 2000 HV) but is very brittle, it performs very well in pure abrasion applications but if subjected to impact fails prematurely. The maximum size is limited to around 10 mesh (2mm) due to its structure.
Sintered Tungsten Carbide
Produced from very fine tungsten carbide (1-3 micron) cemented together with cobalt (6-20%) often with other elements (titanium tantalum etc) to a variety of characteristics. Hardness is typically 1600 HV and is very able to withstand impact. Sintered grit is manufactured from recycled tungsten carbide.
The standard grade contains titanium and tantalum and is generally used for hardbanding, where the grit is poured into a MIG weld pool producing the lowest cost tungsten carbide based hardfacing.
An alternative grade is also available free of titanium and tantalum, which is better suited when the grit is being applied using brazing techniques.
If you are looking for a solution to sliding, impact, or abrasive wear damage,look to our tungsten carbide chips.It is unique answer to the wear challenges in underground mining, surface mining, material crushing, tunneling, and road construction,etc.
Tungsten carbide chips:
1, lasts up to 6x longer than standard steel wear solutions.
2, resists wear before it starts, which means less downtime and maintenance costs.
3, is our specially formulated cemented carbide chips.
1, Use small carbide chips when proxessing fine-grained abrasives like sand.
2, Small carbide chips fit closely together and prevent fine-grain abrasives from wear away the steel matrix between the chips.
3,Use large carbide chips for processing large-grained abrasive like asphalt.

Tungsten Carbide Grit, is cemented Tungsten Carbide Cobalt chips. It is produced from specially selected and graded powders, which are sintered into solids before being broken down to grit. All products are of premium quality, manufactured with care and attention
in order to achieve and exceed international standards. Tungsten Carbide Grit, being harder than Chromium Carbide and most traditional hard facing materials, provides an effective combatant against abrasion wear. Material is supplied in sizes from 12.7mm down to 45 micron. Particle shape is important, with the sharp blocky chips being used in cutting grade Composite Rod. The rounded blocky chips are used for GMAW, welding rods and wear grade Composite Rod. Deleterious materials are removed to avoid detrimental effects to the weld process. Quality checks including sizing, particle shape, chemical composition, oxide levels and cleanliness are undertaken during manufacturing and prior to delivery.
Our products and any recommended practices, should be tested by the user under actual service conditions to determine their suitability for any particular purpose. The results obtained using this product / information are affected by variables such as welding procedure, base material composition, operating temperature, weldmet design, method of fabrication and service requirements which are beyond our control. It is the sole responsibility of the user to determine the serviceability of a structure using this product and the information contained in this data sheet. The technical information given in this data sheet reflects the present state of knowledge and does not form part of any sales contract as guaranteed properties of the delivered materials.
The use of Tungsten Carbide Grit, because of its abrasion resistant qualities, is visible in varying applications of wear. A few of the Industries are listed below, as well as most of the components that Tungsten Carbide Grit is used on.

Multi-application product: Tungsten carbide grits
Tungsten carbide grits/granules are widely used in various industrial applications where a high level of abrasion and corrosion if predicted within the work environments like in the oil industry. The granule size can be altered to achieve the desired levels of impact. The method of hardfacing involves the applying of a tougher and harder metal like tungsten carbide to a base metal. This creates stronger tungsten carbide granules for usage in oil industries and other sectors where high protection against wear and abrasion is required.
High purity Tungsten carbide grit , also called cemented carbide granule or WC grit , is an excellent hard-facing wear resistant materials, widely used on the surface of those who produce severe wear , friendly protect workpiece, increase its efficiency and extend lifespam. The tungsten carbide pellets will produce an extremely aggressive cutting or grinding surface, increase the wear life of hardfacing deposits.
The making process
The traditional process of making tungsten carbide granules involves the crushing of larger compositions of tungsten carbide. The same however resulted in sharp faceted, irregular shaped particles without the much-needed wear resistance. The irregular shapes often succumbed to high pressure and wear conditions which made them a poor choice for oil industries.
The modern process, however, relies on preparing tungsten carbide powder with which different shapes like spheres, cylinders, ovoids, etc are created using a suitable organic binder for use in tough work environments. These so formed tungsten carbide granules provide high strength and wear resistance making it suitable for working in the oil industry.
Tungsten carbide grit have a wide application ranging from use in grinders, agricultural industry, use in wear parts and plow attachments, etc. The usage of tungsten carbide grits in the oil industry in applications like hardbanding, drill pipes, drill collars, pup joints, etc is well noted.
