VK10 vs YG6

Ceramic · grade comparison

VK10 and YG6 are both ceramic grades. YG6 is the more ductile: elongation 0.2% versus 0.1% for VK10, and YG6 is harder (1,580 HV vs 1,290 HV). VK10 is lighter (14.4 g/cm³ vs 14.9 g/cm³ for YG6) and YG6 is stiffer (630 GPa vs 580 GPa).

VK10Choose it when weight is the constraint.

YG6Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

VK10 vs YG6 — frequently asked

What is the difference between VK10 and YG6?

VK10 and YG6 are both ceramic grades. YG6 is the more ductile: elongation 0.2% versus 0.1% for VK10, and YG6 is harder (1,580 HV vs 1,290 HV). VK10 is lighter (14.4 g/cm³ vs 14.9 g/cm³ for YG6) and YG6 is stiffer (630 GPa vs 580 GPa).

Which is cheaper, VK10 or YG6?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

When should I choose VK10 over YG6?

Pick VK10 when weight is the constraint. Pick YG6 when the part is bent, formed or impact-loaded, or when the part sees heat.
