Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), aluminium (Al), or silicon (Si). [1] They are used in the production of steels and alloys.
Shamans and their practices continue in some parts of the Philippines. [205] The art of constellation and cosmic reading and interpretation is a fundamental tradition among all Filipino ethnic groups, and the stars are used to interpret for communities to conduct farming, fishing, festivities, and other important activities.

The Ferro Alloys produced are High Carbon Ferro Chrome, Low Carbon Ferro Chrome, Silicochrome, Silicomanganese, and Magnesium Ferrosilicon, Ferromanganese etc., These alloys are tapped from electric arc furnaces in the molten state. They are prepared to the required size from 25 mm to 150 mm and transported to the various steel companies.
