Product Description

Black annealed low carbon wire is manufactured by cold drawing followed by heat treatment to produce a clean and smooth finish. It offers excellent ductility and moderate tensile strength, making it ideal for tying, bundling, packing, shelving, and general fabrication tasks. With a diameter range from 1.6 mm to 12.5 mm, this wire is commonly used in supermarket trolleys, baskets, racks, hooks, and general automotive components. The annealed surface enables easy handling and moderate bending, while still retaining good mechanical performance.
