UF-B Ultrafine Iron Powder
UF-B is an ultrafine iron powder grade mainly used for diamond tools, cutting segments and related bonding applications requiring fine particle size, high sintering activity and reliable bonding performance.
Product Overview
UF-B is an ultrafine iron powder grade designed for diamond tools, cutting segments and related bonding applications. It provides fine particle size distribution, stable chemical composition, high sintering activity and reliable bonding performance.
It can be reviewed as an alternative to carbonyl iron powder in applications requiring high strength, high hardness and improved diamond holding power.
