Metal fiber is produced by the technique of bundle drawing with metal wire, and the diameter of fiber can be from 2μm to 40μm. The material includes stainless steel fiber, fecralloy fiber, nickel fiber, hastelloy fiber etc. Shaved fiber can also be menufactured. Metal fiber has outstanding properties like electric conductivity, heat conductivity and corrosion resistance, even softness similar to chemical fibers. Metal fiber is widely applied in the fields of textile, filtration, metallurgy and paper, covering all aspects of industrial, civil, military etc.
