Tungaloy has unveiled its latest development of a polycrystalline diamond (PCD) grade that is designed to provide exceptional wear resistance in superhard non-ferrous metals. DX200 is made of 100% pure diamond using no binder to make the bond between the diamond grains.
Boasting the highest hardness of all PCD grade lines, DX200 is best suited for finish machining of carbide and hard, brittle materials, primarily tungsten carbide, cemented carbide, and metal matrix composites (MMCs). In addition, the PCD cutting edge features an excellent edge-line security and sharpness, permitting the insert to achieve superior dimensional accuracy over extended periods of time.
Unlike traditional PCD grades that use a metallic binder such as cobalt to make the grains bond to one another, DX200 directly binds the diamond particles without using binder materials. This allows the grade to have an extremely pure cutting edge, making it an extremely effective tool for machining application-specific components that demand high levels of material purity, such as metal medical implants and sputtering targets for semiconductor applications.
DX200 grade is available in seven inserts of CCGW and DCGW shapes with 0.2 and 0.4 millimeter nose radii.

composites
Materials composed of different elements, with one element normally embedded in another, held together by a compatible binder.
- hardness
hardness
Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.

polycrystalline diamond ( PCD)
Cutting tool material consisting of natural or synthetic diamond crystals bonded together under high pressure at elevated temperatures. PCD is available as a tip brazed to a carbide insert carrier. Used for machining nonferrous alloys and nonmetallic materials at high cutting speeds.

- tungsten carbide ( WC)
tungsten carbide ( WC)
Intermetallic compound consisting of equal parts, by atomic weight, of tungsten and carbon. Sometimes tungsten carbide is used in reference to the cemented tungsten carbide material with cobalt added and/or with titanium carbide or tantalum carbide added. Thus, the tungsten carbide may be used to refer to pure tungsten carbide as well as co-bonded tungsten carbide, which may or may not contain added titanium carbide and/or tantalum carbide.
- wear resistance
wear resistance
Ability of the tool to withstand stresses that cause it to wear during cutting; an attribute linked to alloy composition, base material, thermal conditions, type of tooling and operation and other variables.
