Yg6/ Yg8/ Yn6/ Yn13/ Yg6X Grinding Tungsten Carbide Balls for Ball Mill

Product Description

Product Description Tungsten carbide ball/TC alloy ball High precision tungsten carbide balls /Tungsten alloy ball Tungsten Carbide ball is mainly composed of high-hardness refractory metal carbide (WC, TiC) micron powder with cobalt (Co) or nickel (Ni), molybdenum (Mo) as binder in vacuum furnace or Sintered powder metallurgy products in hydrogen reduction furnace.
Nowadays common cemented carbides have YG, YN serials.

Porosity: A02, B00, C00 (Max.)
Grain size: medium to coarse
Specification: The size of range is available from 3/32" to 2" inches, the tolerance grade is divided into G10, G25, G48, G50, G100 and so on.
The available grades and sizes are shown in the below table.

Grade	Composite	HRA(Hardness)	Density(g/cm³)	T.R.S(MPa)	Description
YG6	6% Co	91	14.6-15.0	1600	The highest wear resistance make this an excellent general purpose grade for use in pumps and valve
YG8	8% Co	89	14.4-14.8	1800	With better shock resistance than YG6, This grade is typically used as a mining grade where thoughness and abrasion resistance are also important .it has also proven useful in bearing applications
YG6X	6% Co	92	14.6-15	1850	Sub-micro alloy, high hardness and wear resistance than YG6, little lower toughness than YG8, Used in parts where high wear resistance and high toughness are required.
YG13	13% Co	90.5	14.1-14.5	1950	high toughness and hardness grade.
YN6	6% Ni	90	14.5-14.9	1450	The highest hardness and wear resistance and corrosion resistance. Used in parts where corrosive condition in high temperature are required.
YN8	8% Ni	88	14.4-14.8	1650	With higher hardness and wear resistance. Used in parts where shock resistance and corrosion are required.
YN9	9% Ni	88	14.4-14.8	1900	With higher hardness and wear resistance. Used in parts where shock resistance and corrosion are required.
YN12	12% Ni	86	14.0-14.4	1800	Higher toughness for impact load. Used in parts where better shcok and impact are required.
