Red brass

Red brass is a copper-zinc alloy with a high copper content (typically around 85 %) and, in many cases, a small addition of tin. Its distinctive reddish-golden color sets it apart from yellow brass, which contains more zinc. Red brass combines good mechanical strength, excellent corrosion resistance, and outstanding workability, making it a preferred material in both technical and decorative applications.

Key properties

• Reddish appearance – Highly valued in design, architecture, and visible components
• Excellent corrosion resistance – Suitable for drinking water systems and mildly aggressive environments
• Good mechanical strength – Maintains shape and load-bearing ability even in thin-walled components
• Excellent soldering and brazing properties – Ideal for piping and joining applications
• Good machinability – Especially in leaded variants (e.g. CuZn33Pb1Sn)
• Moderate electrical conductivity – Usable in certain electrical applications

Typical applications

• Sanitary and plumbing systems – Fittings, valves, and water-carrying components
• Piping and HVAC systems – Soldered fittings and compression connectors
• Electrical engineering – Terminals, contact elements
• Decorative hardware and design – Components with a warm, premium metallic tone
• Mechanical engineering – Bearings, gears, sealing rings
