Foundry Sand AFS 60-70 is basically chromite sand which is reckoned for its excellent thermal attributes. It possesses quick chilling attributes and it can prevent liquid metal penetration. Its thermal expansion rate is less than silica sand. Foundry Sand AFS 60-70 is used for casting of manganese steel, chromium nickel and also for chromium. Due to its low reactivity level, this substance shows less reactivity when exposed to manganese oxide. As its result, its exposure to Mno minimizes the possibility of calcinations. It can easily integrate with all types of molds. This substance has been processed under controlled temperature to ensure about its flawless quality.
