Casting properties of vermicular graphite cast iron

The as cast matrix structure of vermicular iron is characterized by high ferrite content (40% ~ 50% or higher), but pearlite stabilizing elements (such as copper, tin, antimony, etc.) can also be added to obtain as cast pearlite matrix with a content of about 70%. Pearlite matrix can also...

Chemical composition of vermicular graphite cast iron

Vermicular graphite cast iron is a kind of gray cast iron with transition form between flake and spherical graphite. It is a new engineering structural material characterized by good mechanical and thermal conductivity and low section sensitivity. Vermicular graphite cast iron appeared in the 1960s as a new type...
