Choosing Rake Angles for Carbide Inserts Material and Machining Considerations

Tungsten is represented in the period table by the symbol W and atomic number 74. It is a greyish white natural metal that is available in the form of chemical compound. In its raw form, it is a brittle metal which is difficult to work and thus find usage in applications such as drawing, extruding, forging, and sintering.

Source:

Tungsten is commonly found in 4 main minerals: Ferberite, Hubnerite, Scheelite and Wolframite.

Traits of Tungsten Heavy Alloys:

• Tungsten has highest melting point at 3422 degrees Celsius, owing to its tensile strength, and has lowest thermal expansion coefficient of all pure metals.
• It has high density creating a shield against X-ray and gamma radiation.
• Tungsten is resistant to acid, alkalis, and oxygen. The resistant to corrosion feature makes it one of the most sought after metal alloys in the market.
• Even though, it is a heavy element, Tungsten plays a good role in the biological function. It is used by different types of bacteria and enzymes.

Industrial Usage:

Tungsten is widely used to produce hard material, commonly Tungsten Carbide. It is also used to make steel alloys like high speed steel. Tungsten Heavy Alloys are used to manufacture a wide range of Machining Inserts products that requires high strength and robust structure. Moreover, 10% of the entire Tungsten is used to form a wide variety of chemical compound.

Production:

China is the largest producer of Tungsten and the estimated production is more than 55,000 tons. The figure represents the 83% of total production of Tungsten in the world. Apart from China, countries that produce Tungsten are Brazil, Canada, Austria, Portugal, Russia, Bolivia, Peru, Rwanda and Thailand.

Property Enhancement of Tungsten Heavy Metal Alloys:

Tungsten heavy metal alloys are treated with high temperature and various other techniques such as liquid phase sintering, infiltration, and back-casting. Here is the list that describes these processes:

• Infiltration: In this WCMT Insert process, a sintered based material is developed from the component having high melting point and then infiltrated with the liquefied component having lower melting point. Herein, properties of the individual components remain same. This type of hybrid material shows excellent thermal conductivity and thermal expansion values.
• Liquid phase-sintered: It is developed from the mixture of metal powders wherein metals having lower melting point and higher melting point are melted together. In binding phase, metal like Tungsten dissolves and provide its extraordinary characteristics of density and elasticity to the material.
• Back-Casting: In this process, material is bound at a very thin junction and fused in a mould to develop a bond of small size varying only in micrometres.

Apart from the above, various machining processes are adopted such as lathing, drilling, milling, and grinding to carve out exact shapes and sizes. Special processes like lapping, cavity sinking, polishing and others are done on the Tungsten Heavy Alloys to improve upon the features. Tungsten alloys are used to make diamond cutting machines and various others wherever characteristics like high strength is valued. However, it is suggested to buy Tungsten Heavy Alloys from the companies that follow advanced processing techniques and assure competitive rates.
