Tungsten Carbide Rod Manufacturing Industry. Attractive Opportunities in "Tungsten Carbide Rod Production" for Mining & Construction Industries
Tungsten carbide, an important member of the class of inorganic compounds of carbon, used alone or with 6 to 20 percent of other metals to impart hardness to cast iron, cutting edges of saws and drills, and penetrating cores of armour-piercing projectiles. Tungsten carbide (WC) is an inorganic non-natural compound composed of tungsten (W) and carbon (C). Mono-tungsten carbide (WC), which is stable at room temperature, is of major technical relevance.
Tungsten carbide rods, commonly used to make drill bits, PCB board micro-drill, mold thimble, die top, electrode rods, gong knife, textile industry shuttle, machine journal, machine axis and so on.
Tungsten carbide rods include rods with the shapes of round, rectangular and square, solid rods and rods with one or more straight or coolants. The grades are mostly fine and super fine grain with high performance. Tungsten Carbide Rods are manufactured as standards with one, two, or three holes, straight or twisted to a 30 or 40 degree helix, or solid with no holes. All rods are available in standard lengths of 310 and 330 mm.
Market Outlook
Exports
Exports of tungsten and alloys including scrap decreased drastically to 314 tonnes in 2015-16 from 475 tonnes in the previous year. Exports were mainly to Germany (25%), USA (20%), Sweden (10%), UK and Austria (8% each). In 2015-16, exports of tungsten ore & concentrates decreased drastically to only 1 tonne as against 175 tonnes in the preceding year. Exports were solely to Nepal (100%).
In India, the entire demand can only be met by imports and recycling, as there is no indigenous production of tungsten concentrates. High content of WO3 in the tailing dumps of Kolar can be worked on priority basis to meet the demand.
Tungsten carbide are used in various end use industries such as mining and construction, automobile, electronics, and defense among others. The growing demand from the developing region throughout the globe are the major factors driving the global market of tungsten carbide. The growing government investments in the infrastructural development coupled with the augmenting demand from the automobile sector are other factors contributing to the growth of the market. Among the various end-use industry mining and construction is the dominant segment and expected to show the same trend during the forecast years. The properties such as high tensile strength, corrosion and impact resistance, has increased the demand for tungsten carbide in the mining and construction industry.
Tungsten carbide is one of these metal carbides and exhibits the aforementioned properties. It is produced by the reaction of tungsten hexachloride with methane or methanol, which is the source of carbon in the reaction. Tungsten carbide is an inorganic chemical compound, represented by the chemical formula WC and physically, it is in the form of a fine grey powder. The formation of tungsten carbide involves an equal number of carbon and tungsten atoms. In terms of properties, tungsten carbide is much stiffer than steel and denser than titanium. Its hardness is comparable with precious metals, such as ruby, sapphire and corundum. Owing to tungsten carbide’s high resistivity to abrasion, it is widely used in the manufacturing industry for cutting tools. The only drawback in the application of tungsten carbide is that it can decompose at high temperatures and separate into its initial form, i.e. as tungsten and a carbide.
Tungsten carbides are progressively becoming a part of our daily lives and it is anticipated that their application will increase significantly in the coming future, as they are being produced in large quantities for usage in a diverse variety of products. Growing research & development activities to enhance growth in technology are anticipated to drive the tungsten carbide market, and furthermore support its application in ammunition, jewellery and others over the forecast period.
Increasing high quality demand in end use industries is expected to drive demand for the tungsten carbide market during the forecast period. Superior properties of final finished products of tungsten carbide are expected to fuel demand for the tungsten carbide market in the future. Tungsten carbide has become a popular material in the manufacturing of jewellery, due to its high resistance to scratching and the hardness of the material. Despite these positive attributes, the tungsten carbide market is expected to be restrained by its relatively high cost when compared to other metal carbides. Tungsten carbide is a good replacement for uranium in the manufacturing of ammunition and in many other end use applications. Therefore, the lack of availability of uranium in some regions, and its severe ill effects on the human body is expected to create a significant opportunity for tungsten carbide manufactures. Tungsten Carbide (WC) Market Expected to Boost the Global Industry Growth in the Near Future.
Growing end use industries such as automotive industries and increase in the demand of wear resistant materials is anticipated to boost the market of cemented carbide and ultimately will drive the global tungsten market. Tungsten has its application in electronic and electrical components such as electron emitters, lead-in wires and electrical contacts and these industries are forecasted to grow, leading to the increase in global tungsten market. The ability of tungsten to withstand arcing and resistant to corrosion makes it suitable to be used in voltage regulators, though demand of these application is minor but it still contributes in the global tungsten market.
The global tungsten carbide market is segmented into grade type and end user industry. On the basis of grade the market is segmented into general purpose grade, metal foaming and wear grades, submicron grades, rotary drilling and mining grades, and corrosion resistant grades. On the basis of end user industry the global tungsten carbide market is segmented into mining and construction, oil and gas, electrical and electronics, automobiles, defense and others.
