Metal Fibers

Stainless Steel Fibers

Stainless steel fibers are manufactured using the bundle drawing process, in which stainless steel wires are bundled into a tube and drawn through a die to produce a fine fiber with a diameter ranging from 1 to 40 microns (up to 60 times thinner than human hair). Stainless steel fibers exhibit all the common features of the metal, yet are flexible enough to be transformed into knitted, braided, woven, or nonwoven metal fiber and fabric products. They can also be spun and twisted with other fibers such as wool, nylon, cotton, and synthetic blends to produce a variety of textile materials. Our common fiber types include 316L, 302, 304, 430, 434, Hastelloy and Inconel.

Stainless steel fibers possess many beneficial properties, such as good electric and heat conductivity, high corrosion and thermal resistance (400-600°C), and excellent EMI and ESD shielding capabilities. These factors allow stainless steel fibers to be used throughout numerous consumer and industrial applications in diverse fields, including the textile, electrical, filtration, petrochemical, metallurgy, environment protection, papermaking, military, and aerospace and aviation industries.

Stainless Steel Fiber Technical Specifications
Diameter (µm) Filaments (f) Strength (cN) Elongation (%) Resist. (KΩ/m)
6.5 3500-7000 20.68 ≥ 4.5 ≥ 1.0
≥ 3.0 ≥ 0.8
8 2250-4500 13.65 ≥ 6.5 ≥ 1.0
≥ 4.0 ≥ 0.85
12 2000-4000 6.07 ≥ 17 ≥ 1.1
≥ 13.5 ≥ 0.9

Notes:
  1. The diameter of the fiber can be produced between 2 and 100 microns according to customer needs
  2. The fiber’s filaments and breaking strength can be controlled per request
  3. The fiber’s room temperature resistance will change along with the state of the stainless steel

Fecralloy Metal Felt

Fecralloy (Iron-Chromium-Aluminum Alloy) is a type of electrothermal alloy with high resistivity, small temperature coefficient, long service life, high surface load, and excellent oxidation-resistance at elevated temperatures. Fecralloy nonwoven fiber is produced by bundle drawing Fecralloy (AISI 47) wires to fibers with diameters of 8-40 microns. Compared to stainless steel fiber, Fecralloy fiber is even more resistant to high temperatures and is often utilized in vehicle exhaust pipes and high temperature filtration felt and burners.
