ShanSun produces a full standards set by the American National Standards Institute(ANSI) and offers a variety of synthetic diamond powders for resin bond, metal bond, and electroplated bond. Micro-powders for polycrystalline, polishing & super-finishing industry.

1),  Type RVD:

in making resin bonded systems for grinding are proto-diamond, low strength materials, friable diamond.

	RVD-Y  irregular surfaces, low impact strength, provides excellent performances in self-sharpening feature and strong retention to bond. It is widely applied to resin bond diamond tools for grinding and polishing hard metals, ceramics, optical glasses, etc. mesh: 50/60, 60/70, 70/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400, 400/500
	RVD-B  with sharp cutting edges, highly irregular surfaces, with black colour, lower impact strength, performing highly self-sharpening feature and strong retention to bond. In making fine processing ceramics, optical glasses, etc. mesh: 60/70, 70/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400, 400/500

2),  Type JR:

in making metal bonded systems are crushed from RVD proto-diamond, a little higher strength than RVD materials, friable diamond, lighter colour, and a less impurity.

	JR-1b  is highly irrejular crystal with rough surface, more diamond grains in flat or long shape, low impact strength. For grinding and polishing carbide, fine ceramics, variety of glasses and hard stones, etc. Mesh: 50/60, 60/70, 70/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400, 400/500
	JR-1  is irrejular crystal with rough surface, a little higher impact strength than JR-1b. Suit for grinding/polishing non-ferrous metals and non-metallic materials, PCD, carbide, fine cermics, glass, granite, etc. Mesh: 50/60, 60/70, 70/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400, 400/500
	JR-1A  is better crystal with rough surface, these powder are sorted from JR-1 powder with shape-sorting machine, with almost block shape, higher strength and medium impact strength, in making metal bonded or electroplated products, grinding/polishing PCD, carbide, fine cermics, glass, stone, etc. Mesh: 50/60, 60/70, 70/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400, 400/500

3),  Type MBD-4, MBD-6 & MBD-8: are proto-diamond.

	MBD-4  are almost block shape with rough surface, medium impact strength, It is used in metal bond wheels and electroplated products for grinding of brittle non-metal materials and hard alloy. Mesh ：40/50, 50/60, 60/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400, 400/500
	MBD-4A  are almost block shape with rough surface, a higher impact strength than MBD-4. It is used in metal bond wheels and electroplated products for grinding of brittle non-metal materials and hard alloy. Mesh ：40/50, 50/60, 60/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400, 400/500
	MBD-6  are a better crystal with high impact strength, contains cubo-octahedron crystal. It is used in sawing and drilling tools, grinding/polishing stone, alloy, carbide, magnetic materials, etc. Mesh ：50/60, 60/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400, 400/500
	MBD-8  are a better crystal with smooth surface, complete cubo-octahedron crystals, with higher impact strength and thermal stability.  It is used in sawing and cutting tools, grinding/polishing stone, alloy, carbide, magnetic materials, etc. Mesh：50/60, 60/80, 80/100, 100/120, 120/140, 140/170, 170/200, 200/230, 230/270, 270/325, 325/400, 400/500
