HV-50 (Tungsten-Carbide) This HVOF coating incorporates 5% chrome to add excellent corrosion resistance along with its great wear resistance. This added 5% chrome also allows this coating to have mirror-like finish when ground and polished.
Pure tungsten carbide (WC) is an interstitial compound of a transition metal, tungsten, and carbon. The bond is complex and hybrid with a percentage of metallic bonding, covalent bonding and ionic bonding.
Overview. GAOTek Leeb Hardness Tester with Tungsten Carbide (Bluetooth, USB) is a compact and easy to use hardness tester used to test the structural integrity of a metal object by applying a definite amount of force on the object and is equipped with USB port and thermal printer with Bluetooth module.
Tungsten carbide is a homogenous mixture of tungsten carbide grains in a tough cobalt binder matrix. The tungsten carbide grains are fused into a solid matrix of cobalt metals. The term cemented carbides comes saying that the metal carbide's grains are "cemented" in the binder metal's matrix. The fusion process is called liquid phase sintering, or sinter for short.
Manufacturing of Tungsten Carbide Products Tungsten Carbide is a composite material manufactured by powder metallurgy. The wear resistant composite is usually Wolfram Carbide (WC) with cobalt (Co) binder.
DURMAT ® WSC Fused Tungsten Carbide Hardness: 2,360 HV 0.1 Chem. composition: WC-W 2 C Applications: Deep well drilling tools and rods, crusher jaws, mixers, concrete and stone saws, hot-pressed tools, screens & conveyors, extrusion housings, hard additives to diamond bits and saws
Unlike traditional tungsten carbide, FEROBIDE uses a steel matrix to bond tungsten particles together. The unique forming process yields very high wear resistance combined with a superior impact and chipping resistance. FEROBIDE consists of high-quality tungsten carbide, with a typical hardness of 1500 HV.
This allows the M3™ to produce impermeable tungsten carbide coatings with hardness of up to 1670 HV 300 and negligible W 2 C content. Standard HVOF cut powders (-45+15 μm) can also be sprayed with hardness of 1350 HV 300 .
Tungsten carbide with a Vickers number of 1700-2400 (85 HRC equivalent) is composed of 90% carbide particles by weight, 80% by volume. Most standard wear resistant alloys contain a maximum of 35% by volume of softer chromium carbide.
Spherical Cast WC Powder Extremely hard and dense, Tekna' Spherical Cast Tungsten Carbide powder, an eutectic mixture of WC and W2C phases, is within the most wear resistant products on the market. Commonly blended with nickel based alloys, it is perfect for hardfacing applications by PTA, laser cladding and other processes for use in applications where wear protection is needed, such as ...
Carbides and carbide materials have excellent wear resistance and high hot hardness. They are sometimes referred to as hardmetals. Applications include wear parts and tooling, chemical and material processing, building and construction, and walls and roofing.
Technosphere : Spherical cast Tungsten Carbide grains – Hardness 3000 HV ± 500 HV The difference lies in the use of spherical Tungsten Carbide grains called Spherotene®. The spherical shape and the extreme hardness of the Spherotene® give Technosphere®, amongst other properties, two advantages:
Tungsten Carbide Insert Bit, also known as a tungsten carbide bit is a cutting tool that is primarily used in drilling applications to crush or cut rocks. Tungsten carbide consists of equal amounts of tungsten and carbon atoms which make it a very hard metal as compared to other metals and is thus, considered as a suitable material for manufacturing of drilling bits.
Carbide Grades The production of carbide involves a process the complexity of which is, in fact, extraordinary. The base materials, tungsten carbide and cobalt, are combined by applying an exceptionally wide variety of mixing ratios.
Tungsten, Cobalt, and More on Mohs Scale of Mineral Hardness. A mineral is traditionally defined as a compound that is solid, and which is found primarily in nature. While there are a number of ways in which minerals can be studied, their degree of hardness being one of them. The Mohs scale of mineral hardness is a chart that categorizes minerals according to their scratch resistance, as well ...

Tungsten is a greyish-white lustrous metal, which is a solid at room temperature. Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength. It has excellent corrosion resistance and is …
The hardness value of tungsten carbide is 1600 HV, which is ten times higher than steel. There are two types of drill bits that are used in the oil and gas industry, i.e., rolling cutter bits and fixed cutter bits.
H.C. Starck offers two grades of high quality tungsten titanium carbide powder with various tungsten/titanium ratios: in the standard grade (W,Ti)C S the ratio is 50/50. The (W,Ti)C HV grade with even fewer impurities is available with a 50/50 ratio and a 70/30 ratio. Both grades are available with grain sizes of 1 µm and 3 µm. We provide technical support in the selection of the suitable ...
