Our monocrystalline synthetic diamond powders have very strict control to insure consistent premium quality synthetic diamond powders. The resin and metal bond system diamonds are available in a variety of grades and sizes, along with the mesh sized diamonds of different hardness, all in compliance with the US Bureau of Standards. Metal bond diamonds are best suited for 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.

Recommended Application
The following is a list of recommendations to maximize the performance of the polishing or lapping operations.
- Match the polishing pad characteristics to the material to be polished
- Charge diamond at higher pressure than the lapping process
- Use a polishing lubricant designed to remove polishing or grinding swarf. This can significantly increase the life and performance of the polishing surface
