Gray cast iron is a kind of iron-carbon alloy and it gets its name “grey” from the fact that their cutting sections looks grey. The metallographic structure of gray cast iron is mainly composed of flake graphite, metal matrix and grain boundary eutectic. During the grey iron, the Carbon is in the flake graphite. As one of the widely used casting metals, cast gray iron has many advangates in costs, castability and machinablity. We are open for long-term beneficial cooperation relationship and ready to become your reliable manufacturing partner in China. To be your expert partner in the field of sand casting.

Green Sand casting process offers the greatest flexibility and the most cost-effective tooling. Our sand casting foundry is equipped with a complete metallurgical laboratory to determine the chemical and mechanical characteristics of each melt and to analyse the metallugic condition of the molten metal before pouring. Microsections are examined under the microscope to obtain final information on the solified casting. We issue 3.1 certificate for each delivered part on customer request.
