The production of jewellery is among the newest applications for tungsten carbide that’s gaining a reputation. Tungsten carbide wedding bands, and scratch-resistant watch cases, watch bands and watch buckles have gained in popularity as it is virtually impossible to scratch, have a beautiful shine and are less expensive than other metals.

For example, tungsten is used as an interconnect material in ICs (Integrated Circuits), between the silicon dioxide dielectric material and transistors.

Tungsten refers to the individual metal whereas tungsten carbide is an inorganic non-natural chemical compound composed of equal parts tungsten (W) and carbon (C) atoms.

Tungsten carbide is an effective neutron reflector. It was used during early investigations into nuclear chain reactions, particularly for weapons.

Tungsten metal is a chemical element, often referred to by its Latin name –Wolfram. It has a chemical symbol of W and an atomic number of 74. An important member of the transition metals on the periodic table,  It is solid at room temperature; with an appearance is light grey-white.

Tungsten carbide rings are often referred to as ‘tungsten’ rings for simplicity. A 100% tungsten ring, as a standalone metal, is quite difficult to construct into a ring and would not be as durable or corrosive resistant as a tungsten carbide alternative. However, one has to make sure that they are indeed purchasing tungsten carbide. A good indicator of this is the price; low-priced tungsten carbide rings are often made of weak materials.

High-precision Tungsten carbide machining tools are preferable to HSS (High-Speed Steel) because of their superior hardness, high wear and tear resistance, and ability to withstand higher working temperatures,  allowing for higher cutting speeds and feed rates.

Tungsten carbide is highly resistant to corrosion and can be used in a wide range of corrosive environments and outdoor applications.

➢ Setting stones into tungsten carbide rings requires the use of a high-power laser machine.  Due to the non-malleable property, tungsten carbide rings are cut with precision to the exact diameter of the stone to ensure it is held securely.

More than half of the world’s tungsten is utilised in the production of hard materials, such as tungsten carbide –the hardest material known. This exceptionally hard tungsten compound is priceless in the construction of cutting, drilling, filing and boring machines – creating components that take significantly longer to wear down, work much more effectively, and greatly boost the cost-effectiveness of the tools and machinery in which tungsten carbide is used.

Due to its exceptional properties, tungsten metal has found uses in numerous industries, ranging from jewellery and sports to surgical instruments, aerospace engineering, high-speed tools, nuclear shielding, alloys and compounds, chemical applications and electronics.

Tungsten metal is widely used in the electronics industry due to its high conductance, inertness and environments involving high levels of radiation. For this reason, along with its very high density, tungsten is one of the main sources of metal for X-ray targets because the relatively inert, very high-density material is difficult for X-rays to penetrate.

The scrap of tungsten carbide products is extensively utilised in the manufacturing, petrochemical, construction, gas drilling and mining sectors. The comparatively lesser price of tungsten carbide as compared to other metals and alloys provides new avenues for its utilisation in the modern world.

Tungsten carbide has a high melting point (5,200°F) which makes it an excellent material for high-temperature environments.

The Tensile strength of tungsten metal is 980 megapascals (MPa), which makes it much stronger than cast iron (200MPa), structural steel (550MPa) and even stainless steel (860MPa). Tungsten is the strongest naturally occurring metal on Earth.

It’s extremely dense, with an atomic weight of 183.84, and has a very high melting point – boasting the highest melting point of all refractory metals. It exhibits excellent tensile strength and resistance to corrosion.

The affordability, strength and resistance to scratches and corrosion make Tungsten carbide rings a unique choice. However, once made, tungsten carbide rings cannot be resized easily due to their brittleness.

Tungsten benefits from a very high density. At 19.3 g/cm3, tungsten is amongst the highest of all other metals. As a result, tungsten can hold much more weight in smaller sizes.

Cemented carbide is used to make drilling and mining tools that are required for various construction applications and account for the greatest use of the material anywhere in the world. About 68% of the market is based on mining tips, drill bits, and other cutting, milling, and mining tools.

➢ The next step is polishing. After the sintering process, the raw black alloy is passed through multiple steps of polishing. Due to the high strength of tungsten carbide, diamond polishing paste must be used in place of regular polishing wax or compound. Starting with 90 microns, the number is then reduced in each polishing phase until a fine finish is achieved. A 0.5 micron paste is used for a superior mirror fine finish.

It provides formulas for calculating machining times based on factors like cutting speed, feed, depth of cut, length of cut, number of passes.
