Sponge iron is made from iron ore, which is processed by redox reaction. It has the characteristics of large specific surface area, high activity and easy reaction with oxygen in water to form Fe(OH)3 for filtration.
Sponge Iron powder is produced in many different grades for varieties of applications.
High purity fine iron powders are used to manufacture sintered components, soft magnetic components, brazing, iron fortification, friction products, printing, surface coating, welding, brazing, chemistry and polymer filtrations.Iron powder products are classified by purity, production method, grain and density.
