Company Profile
Hunan Huitong New Materials Co., Ltd. traces its core technology to 1983, when the team operated as the metal fiber plant of the Changsha Research Institute of Mining and Metallurgy. In 2002 the business was spun off as an independent company under China’s high-tech industrialisation programme (State Planning Commission document No. 487, 2001).
The company is registered in Yiyang, Hunan, where it operates a production base of over 100 mu in the Yiyang High-tech Zone. A branch in Changsha’s Lugu High-tech District, also over 100 mu, handles R&D, administration, sales and pilot production. Huitong listed on the National Equities Exchange and Quotations in November 2015 and moved to the Beijing Stock Exchange on 17 July 2023 (ticker 920751).
Technology
Metal fiber is produced by an in-house bundle-drawing process: wire is surface-treated, bundled, drawn, heat-treated and finally electrolytically separated into individual filaments of 1–100 µm. The route covers stainless steel, FeCrAl, nickel, titanium, copper, tantalum and Hastelloy, with filament count and diameter specified per order.
Downstream, fiber is air-laid and vacuum-sintered into multilayer felt for higher dirt-holding capacity, or blended and stretch-broken into conductive yarn, composite thread, tow and blended tow.
Products and Capacity
- Fibers: 1–100 µm; stainless steel, FeCrAl (typically 8–40 µm), nickel, titanium, copper, tantalum and Hastelloy C276/C59.
- Products: woven and blended metal fabrics, sintered felt, composites, conductive blended yarn, conductive masterbatch (60% and 75% fiber loading) and burners.
- Capacity: more than 500 t of metal fiber per year; stretch-broken tow at 38–110 mm and 2–10 g/m.
Applications span automotive, textiles, petrochemicals, chemicals, telecommunications, environmental filtration, fuel cells and new energy.
Recognition
The company is a national “Little Giant” specialist enterprise and a high-tech enterprise, and hosts the Hunan Provincial Engineering Technology Research Center for Metal Fibers and Products. It holds a portfolio of core patents in metal fiber and related products.
