Description

SMP SmartMicron diamond powder is made of modified synthetic diamond. SmartMicron diamond products deliver outstanding performance in lapping processes of superhard materials such as sapphire, ceramics and hard metals. Compared to conventional diamond powders, SmartMicron diamond powder delivers typically 10–20 % higher material removal rates (MRR) at equivalent values of surface roughness.

Best performance: For best performance, we recommend to use SmartMicron products incorporated in our state-of-the-art diamond suspension formulations. The product range includes oil based and water soluble suspension formulations.

This material data has been provided by Pureon.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
