Carbide burrs

It is widely used in grinding the welding joint in aircraft manufacturing, ship manufacturing and automobile manufacturing.

Grade	Co.content （%）	Hardness （HRA）	Density (g/cm3)	Bending strength （N/mm2）	Particle size	Application
YG6X	6.2	92.3	14.88	2600	Fine grain	Used for carbide burrs.
YG7	7	90.5	14.80	2600	Medium grain	Used for carbide burrs.
YG7A	7	91.0	14.80	2800	Medium grain	It is an improved version of YG7, and has better wear-resistance than YG7, but its toughness is decreased slightly.
