Brass rods are classified by cross-sectional shape as round or hexagonal, and by processing condition as as-extruded or cold-drawn. They are widely used in construction, automotive manufacturing, mechanical engineering and many other industries, where their high corrosion resistance and good machinability make them a preferred material. Their mechanical properties support the production of durable components, while common applications include electrical connections, decorative products and a wide range of engineering components.
