What is YG20?

YG20 is an advanced moulding material consisting of insoluble metal carbides and a cobalt or nickel binder.This carbide has high hardness,good wear resistance and red-hardness,but is brittle.It has a hardness range of 83-86 HRA,a density of 13.4-13.7 g/cm3,a tensile strength of 2600 MPa,a flexural strength of 3400 MPa and an impact toughness value of 4.8 J/cm2.

Chemical composition and hardness of YG20

The chemical composition of YG20 includes a steel content of 20%carbon,80%WC and 20%Co.This material is suitable for the production of carbide dies in large batches such as cold punching dies,cold heading dies and cold extrusion dies.In addition,YG20 can also be used in cold extrusion dies for aluminium alloy parts,steel parts and other cold extrusion dies where wear resistance is required,with a recommended hardness value of 62-64 HRC.
