MONO-ECO diamond is a low-cost, monocrystalline metal-bond type diamond. The product is used in cost-sensitive applications, where the diamond cost has a major impact on the overall process cost. MONO-ECO micron diamond is available as diamond powder or as ready-to-use diamond suspension

Particle strength: Monocrystalline diamond particles fracture along the parallel cleavage planes running through the particle. For diamond tools, the particle fracture provides a self- sharpening mechanism and thus increases tool life.

Cost-effectiveness: Thanks to its low cost, MONO-ECO diamond is a good choice for price-sensitive applications. MONO-ECO diamond is often used to replace conventional abrasives.

MONO-ECO diamond is a monocrystalline metal-bond diamond produced by HPHT (high-pressure, high temperature) synthesis. The diamond particles feature an oriented crystal structure with parallel-running cleavage planes, similar to natural diamond. Depending on diamond size, MONO-ECO diamond varies in appearance from light gray to pale yellow.
