"brass coil" refers to a continuous length of brass sheet metal that has been wound into a cylindrical shape for ease of storage, transport, and processing. Brass, an alloy primarily composed of copper and zinc, endows this material with excellent strength, corrosion resistance, and electrical conductivity. Its versatility allows brass rolls to be utilized in diverse industries, including electronics, plumbing, architecture, and manufacturing, where they are shaped and cut into components as required.
