M1 Grade

M1- the crystal are irregularly flaky and needle-shape with rough surfaces and mainly used in Resin Bond Carbides Products and producing Diamond Mircopowders

M2 Grade 

M2- with ratio of major axis and minor axis not more than 1.5, irregular and rough surfaces crystal, which is used in manufacturing bronze bond products for grinding carbides and other nonmetallic materials. 

M3 Grade

M3-relatively more regular crystal shape with smooth surface and hence higher compressive strength, for which suitable for manufacturing bronze bond products for grinding, sawing and drilling. 

M4 Grade

M4-almost perfect crystal shape with smooth surface and highest compressive strength. Particularly suitable for mining bits used in hardest strata for dressing tools and saws.

M5 Grade

Perfect shape & clear crystals with excellent performance:

Ti (Strength) for #40/50 =88

Tti (strength) for #40/50=86
