Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments ...
Sintered tungsten carbide's most impressive property is the ability to resist abrasion. It is the hardest metal known to exist. Abrasion resistance can be up to 20 times greater than steel. Most of Kinton Carbide's fabrication involves brazing sintered tungsten carbide platelets to carbon steel back plates.
This article is a guide to machining Tungsten and its allows along with Feeds and Speeds recommendations. It's part of CNCCookbook's material-specific machining guides. Tungsten Properties Tungsten is a hard, rare metal with chemical symbol W. It is also known as "Wolfram". It has many unique properties, for example, the melting point of Tungsten is […]
Tungsten-steel alloys are also used in the production of rocket engine nozzles, which must have high heat resistant properties. Other tungsten alloys include Stellite (cobalt, chromium, and tungsten), which is used in bearing and pistons due to its durability and resistance to wear, and Hevimet, which is made by sintering a tungsten alloy powder and is used in ammunition, dart barrels, and ...
The material commonly known as Tungsten Carbide is a product of power metallurgy and is simply a composition of finely divided particles of pure tungsten carbide locked together in a binder of cobalt with or without additional carbides of titanium, tantalum, niobium or vanadium.
Safety Data Sheet Sintered Tungsten Carbide with Cobalt and/or Nickel Binder Page 3 of 4 8.2 Engineering Controls Use local exhaust ventilation that is adequate to limit personal exposure to airborne dust to levels that do not exceed the PEL or TLV.
Eta phase is a carbon deficient form of tungsten carbide that results in a harder, more brittle cemented carbide part. Insufficient carbon levels are generally the result of improper formulation of the carbide powder, long term exposure of unsintered parts to the atmosphere, or poor control of sintering …
Jan 05, 2018· The effect of cobalt (0.5 wt%, 1.0 wt%, 1.5 wt% and 2.0 wt%), as an alloying element, on the microstructure and mechanical properties of W-Ni-Fe tungsten heavy alloy (WNF) prepared through spark plasma sintering (SPS) process is investigated in this work.
Corrosion Resistance of Tungsten Carbide Grades. Cobalt is by far the most widely used binder metal or "cement" in cemented tungsten carbides because it most effectively wets tungsten carbide grains during liquid phase sintering.
Tungsten powder (0.6–0.9 μm) was sintered by field assisted sintering technology (FAST) at various processing conditions. The sample sintered with in-situ hydrogen reduction pretreatment and pulsed electric current during heating showed the lowest amount of oxygen.
Introducing Kinton Carbide Sintered tungsten carbide's most impressive property is the ability to resist abrasion. It is the hardest metal known to exist. Abrasion resistance can be up to 20 times greater than steel. Most of Kinton Carbide's fabrication involves brazing sintered tungsten carbide platelets to carbon steel back plates. Our brazing process results in...

The WCZ material includes pieces with hardmetal surface coating (generally Titanium-Nitride) on some of the particle surfaces. TYPICAL CHEMICAL ANALYSIS
Sintering: Sintering, the welding together of small particles of metal by applying heat below the melting point. The process may be used in steel manufacturing—to form complex shapes, to produce alloys, or to work in metals with very high melting points. In a steel-sintering plant a bed of powdered iron ore,
Tungsten Heavy Alloys. Heavy metal alloys are pseudo-alloys of tungsten with a nickel-iron or nickel-copper matrix. They are produced by powder metal and sintering processes. The most outstanding property of heavy metal alloys is the high density of 17-19 g/cm³.
