The stainless steel staple fiber is processed with variety of chopped metal fibers along-with fiber length that range in-between 1.0 to 38 mm, which is in the disorder of the state supply accumulation. as the fiber is short in dimension, it can be dispersed in various forms of viscous liquid stirring, and is used in the process of casting, which leads to the production of metal-comprising composite materials. The staple fiber can be used for sintered plates, sintered blankets and other applications related to porous materials. The stainless steel staple fiber is made of nickel based high temperature alloys, brass, copper and aluminium. The main purpose of the staple fiber lies in the making of gas burners, heat storages porous material, conductive plastic master batch, thermal fiber brake pads, diesel exhaust gas purifier and muffler damping briquette.
