Brass H59 is a copper-zinc alloy composed of approximately 59% copper and 40% zinc, offering a good balance of strength, ductility, and machinability. It is a free-cutting brass variant commonly used for CNC machining, particularly when precise tolerances and fine detail are required. H59 exhibits good corrosion resistance in dry environments and moderate resistance to moisture, making it suitable for decorative components, fittings, hardware, and low-load mechanical parts. Its excellent formability and thermal conductivity also make it a common choice in electrical and plumbing applications. While not as strong as bronze or stainless steel, H59 remains a cost-effective and versatile material for functional and aesthetic components.
