Vipul Sheets and Plates provides precise Manganese Bronze Circles made in Delhi, India. Manganese bronze is an alloy of copper, tin, and aluminum that possesses superior strength, wear, and corrosion resistance. Our circles are cut to tight specifications and have clean, burr-free edges and polished surfaces. Suitable for marine props, valve seats, and decorative hardware, we provide top-quality output. Vipul‘s circles meet industry specifications for dimensional accuracy and surface finish, serving sectors such as marine, architecture, and heavy engineering where alloy strength, aesthetic polish, and corrosion resistance are crucial.
Manganese bronze circles have ~60–62% copper, 3–6% tin, 1–3% manganese, and trace amounts of aluminum, iron, or lead for enhanced machinability. Tensile strength is 450–600 MPa, yield strength 150–350 MPa. The alloy is good in wear resistance, fatigue resistance, and corrosion resistance to seawater. It has good ductility and very good machinability, hence best for precision cutting of circles. Manganese bronze circles are excellent for structural and decorative purposes due to the combination of strength and polishability.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Manganese Bronze Circle provide excellent strength, durability and corrosion resistance, making them ideal for marine, industrial and heavy duty applications They are highly resistant to fatigue and wear, providing long service life in the environments tough. Their superior machinery allows for precision and customization. Due to excellent thermoelectric conductivity, these circuits are suitable for applications requiring efficient energy transfer. In addition, manganese lead is highly resistant to dezincification, maintaining its structural integrity over time. Its aesthetic appeal and polish ability make it a favorite for furniture, striking a balance between functionality and visuals.
Manganese Bronze Circles are utilized in pump impellers and marine propellers due to their corrosion resistance and mechanical properties. They find applications as valve seats and bushings in industrial and marine pumps. Decorative architecture uses them for fixture bases, hardware, and medallions. These circles also find applications in gears, bearing races, and washers. Their polish and strength provide them a place in musical instrument hardware and components. Manganese bronze rings provide long-lasting accuracy in both functional and cosmetic uses, particularly where it comes to wet conditions.
