The toughness of SPARK products is greatly improved due to the Nano-ZrO2 component. It can show his special advantage in high linear velocity milling process, can assure no breakage and no damage to the milling machines and save the cost and time for customers on machinery maintenance. Compared to high purity ZrO2 beads, SPARK has similar wear resistance, much lower cost, higher hardness. It is attractive for customers due to its high performance and low package cost, can be used in high stress, high power milling machines, for fine milling of hard materials.
