Sponge Iron Powder (SIP) is mainly used in self-lubricating bearings. The particle shape of SIP has a very porous structure and thus they exhibit a very low apparent density. This helps in self-lubricating properties of bearings and improves oil retention in sintered bushes. High purity SIP has very low content of impurities, this helps in superior welding properties when used in welding flux. As per application requirement, several grades have been designed to provide optimal performance
