Chopped Steel wool fiber is a new type of metal fiber material, with fibers up to 4 μ m. The natural state resembles a fluffy cotton shape. This product is made of special low-carbon cold-drawn steel wire through special processes such as scraping, crushing, and blending. It is the main reinforcing material for sports machinery brakes such as automobiles, motorcycles, trains, and airplanes. It has characteristics such as stable performance, low wear rate, and good heat dissipation.
