Tungsten Carbide Grit

Introduction of Tungsten Carbide Grit

Tungsten carbide grit is composed of cemented tungsten carbide and cobalt chips. It is made from carefully chosen & graded powders that are sintered into solids before being ground to grit. Tungsten carbide grit, which is tougher than chromium carbide and other standard hard-facing materials, is an efficient abrasion wear resistant substance. Material arrives in diameters varying from 12.7mm to 45 microns. Particle form is vital, & sharp blocky chips are employed in cutting grade composite rod. The rounded blocky chips are employed in GMAW, welding rods, & wear-resistant composite rods. To avoid negative impacts on the welding process, hazardous chemicals are eliminated. We also offer steel grit, steel shot, silicon carbide grit, and glass beads in India. 

In heightened abrasive wear zones, tungsten carbide grit delivers long-lasting wear protection. It is employed to safeguard costly components including bulldozer blades, bucket teeth, wood grinding hammers, trencher teeth, & a broad range of additional consumable components. Tungsten carbide grit abrasive media is an effective way to safeguard machines & components by significantly improving their lifespan. This saves downtime & the costs associated accompanied by vulnerable components. Tungsten carbide grit is the sand blasting machine media employed to treat & polish metal, concrete, and other surfaces.Tungsten carbide grit is utilized in hard facing procedures to enhance surface wear resistance & equipment durability.

Tungsten Grit

The usage of tungsten carbide grit in hard facing applications is well recognized. Examples of these applications include rotating rock bits & tool-combined connections, which are mostly employed in excellent drilling and need the tools to endure extreme abrasion & heightened impact pressures. Grits include been produced in past by crushing & screening arrangements including tungsten carbide. Particles accompanied by poor wear resistance that were sharply faceted & irregularly shaped were the result of this process.

It has been found certain a tungsten carbide grit accompanied by blunt, round particles may be produced by mixing tungsten carbide powder accompanied by an appropriate organic binder, authorizing accompanied by the bits to agglomerate into particles certain are sintered to extract binder. A minimum amount of useless acceptable material is achieved together accompanied by a decent output of blunt tungsten carbide grits. Corresponded to tungsten carbide grit constructed from crushed blocks & compacts, blunt tungsten carbide grit encloses more useful wear resistance characteristics.

Tungsten Carbide Grit Size

Tungsten Carbide Grit, furthermore summoned crushed cemented carbide, crushed tungsten carbide, accompanied by 6%, 8%,10% cobalt content & tungsten carbide balance, melting point 3410°C, boiling point 5100°C, density 14.50-14.85 g/cm3, is an assortment of media by crushing tungsten carbide accompanied by cobalt bonded alloy like anvil scrap & additional tungsten alloy bar, rod, inserts & tips scrap to mesh size needed for further application. Tungsten carbide grit contains heightened thermal conductivity, heightened stability & especially more difficult than aluminum oxide.

Tungsten carbide (WC), often understood as cemented carbide, is a compound material made via powder metallurgy. Tungsten carbide powder, whichever typically accounts for 70%-97% of the absolute weight, is integrated chaperoned by a binder metal, usually cobalt & nickel, crushed in a die, & sintered in a furnace. The word "cemented" directs to tungsten carbide grits existing detected in the metallic binder material & "cemented" together, producing a metallurgical link betwixt bits & binder (WC - Co) throughout the sintering process. This substance is repeatedly directed to as "carbide" in the cemented carbide sector, while phrases tungsten carbide & cemented carbide are interchangeable.

Brittle materials have a tiny permanent distortion during failure, while ductile materials have substantial plastic deformation. Carbide is formally categorized as a "brittle" material since it delivers little & no plastic deformation before the commencement of a fracture & complete failure. Without metallic binder phase, tungsten carbide may be considered a ceramic material, similar to silicon carbide & aluminum oxide. A ceramic substance is a combination of a metal and a nonmetal, such as silicon (metal) carbide (carbon, nonmetal), aluminum (metal) oxide (oxygen, nonmetal), & silicon nitride. A cermet is a compound media made up of ceramic (cer) & metallic (met) constituents. Inclusion of a metallic binder, like cobalt & nickel, transforms cemented carbide (WC-Co) into a cermet & differentiates it from really brittle materials, namely ceramic family of materials.

Wear resistance possessions of tungsten carbide grit could be enhanced by using it as a challenging surfacing material. This abrasive media is typically employed in metal-bonded products to abrade tough media like composites, fiberglass, reinforced plastics, rubber, & additional technological elements. Wear-resistance electrode & mace electrode saw blade, rock & stone polishing & granite engraving machine operation, ceramic & metal lapping & polishing applications, glass etching & glass carving industriousness are some of the processes that use this grit.

Properties of Tungsten Carbide

• The melting point of tungsten carbide is still elevated to 2,870C (5,200F).
• It has a boiling point of 10,830F, or 6,000C.
• At one instance, the thermal gravity rose to 110 Wm-1K-1 (100 kPa).
• A thermal increase of 5.5 m·m-1·K-1 is observed. For tungsten carbide coating, tungsten carbide material is utilized.
• Tungsten carbide is very stiff, with a Mohs hardness of 9 to 9.5 & an amazing hardness of about 2600.
• Young's modulus is around 530–700 GPa, majority modulus is roughly 630–655 GPa, & shear modulus is approximately 274 GPa.
• It has the most elevated tensile solidity (344 MPa) & the highest elevated squeezing stability (approximately 2.7 GPa), with a poisson percentage of 0.31.
• At 6220 m/s, a longitudinal wave travels through a thin tungsten carbide rod.
• The much lower electrical resistivity (of around 0.2 m) of tungsten carbide is comparable to that of a few certain metals.
• Melted nickel or cobalt both readily wet tungsten carbide. The degree diagram of the W-C-Co process shows that WC & Co. are still in a pseudo-binary eutectic.
• In WC-Co cemented carbides, monitoring the carbon range is crucial because carbides could develop & these stages are brittle.
• When sintering tungsten carbide in the presence of a molten phase, akin to that of cobalt, abnormal grain elaboration has been seen & is essential to the final material's efficacy.
