Natural Diamond Powders


Our natural diamond powders are presicely graded and have a blocky, sharp-edged particle shapes. Our technology allows the production of different sizes of diamonds to suit most applications

Very strict process control insures consistent premium quality natural diamond powders. Micron and mesh sizes produced in compliance with the US Bureau of Standards. The natural diamonds are also available with copper or nickel coating

Coated natural diamonds are best suited for electroplated diamond tools as well as for grinding wheels, abrasive wet and dry superfinishing and lapping of nonferrous metals, nonmetallics and composite materials, such as Tungsten Carbide, Titanium alloys, Glass, Ceramics and Cermets. They are also well suited for honing and polishing die steels and cast irons, metal plating of diamond tools, dressing and truing silicon carbide grinding wheels.

Most Popular Areas Of Applications

Lapping and Polishing Resinoid Bond Abrasive Diamond Wheels Metal Bond Abrasive Diamond Wheels Wire Saw Slicing
Resin and Metal bond diamonds are very popular abrasive media for free abrasive lapping and polishing applications, suitable for very tight tolerances and very high surface finish applications. They are also a popular free abrasive media to be used with oil, glycol and water based vehicles for lapping and polishing of various materials such as ceramics, carbides and sapphires, etc. Our Resin Bond Diamond powders are dark gray in color, and have medium hardhess and friability index. Resin Bond diamonds are most suitable for use in the resinoid bond abrasive wheels, operating in wet or dry applications. Resin bond wheels are more forgiving resulting in a better finish. Our Metal Bond Diamond powders are harder and tougher than resin bond powder and made for use in metal bond diamond wheels. Metal bond diamonds will meet the demands of harder working conditions. They are used in metal bond wheels for grinding of Quartz, Ceramics, Sapphires and other hard materials. Synthetic Diamonds are becoming more and more popular (and cost efficient) in wire saw cutting applications involving super hard materials such as sapphires and silicon carbide.
