Tungsten carbide grade “YG6″

1.YG6 is suitable for semi-finishing and light load roughing of cast iron, non-ferrous metal, heat-resistant alloy and titanium alloy;

2.YG6A(carbide) is suitable for semi-finishing and light load rough machining of cast iron, non-ferrous metal, heat resistant alloy and titanium alloy.YG6A has good red hardness and is more suitable for high cutting temperature.
3.YG6X is suitable for finishing and semi-finishing of cast iron, non-ferrous metal, heat-resistant alloy and titanium alloy.

Second, the form is different.
1. YG6 is a medium size tungsten-cobalt alloy;
2. YG6A (cemented carbide) is an alloy of tungsten, cobalt and tantalum;
3. YG6X is fine-grain;
Third, the composition is different.
1. YG6 is an alloy with 6% cobalt content;
2. YG6A (cemented carbide) is an alloy with 6% cobalt content and a small amount of TaC added;
3. YG6X is the alloy with 6% cobalt content, but the WC grain used is uniform and fine, and the performance is higher than YG6.
Extended data

Performance characteristics of Cemented Carbide.
High hardness (86 ~ 93 HRA, equivalent to 69 ~ 81 HRC);
Good thermal hardness (up to 900 ~ 1000°C and 60 HRC);
Good wear resistance.
Cutting speed of carbide tools is 4 ~ 7 times higher than HSS, and tool life is 5 ~ 80 times higher. Tool and gage life is 20 ~ 150 times higher than alloy tool steel. It can cut hard materials of about 50 HRC.
But cemented carbide is brittle and cannot be cut, and it is difficult to make a complex shape of integral tool. Therefore, it is often made into different shapes of blades and mounted on the tool body or die body by welding, bonding, mechanical clamping, etc.
