Cast iron milling and turning

Cast iron is an iron alloy with a high content of carbon and silicon. Cast iron has a lower density than steel, better corrosion resistance as well as higher thermal conductivity.

Surface treatments for cast iron turning and milling parts

After turning and milling, cast iron components are often subjected to heat treatment. For this purpose, you can choose from the common processes in our online shop.
