Aiman Metals, with its headquarters in Kuala Lumpur, Malaysia, is a reliable manufacturer and supplier that provides superior quality metal products to various industries. With precision engineering, reliability, and customer satisfaction being the areas of priority, Aiman Metals has developed a reputation as a reliable market leader. Among its top-of-the-line products, Manganese Bronze Bars and Rods are renowned for their superior strength, corrosion resistance, and superior machinability. These properties render them suitable for marine, industrial, aerospace, and heavy-duty engineering uses. Supported by sophisticated manufacturing methods and a pool of expert staff, Aiman Metals assures each Manganese Bronze product to be of superior quality and performance.
Manganese Bronze Bars and Rods generally consist of 58–63% copper, 3–4% manganese, 1–2% iron, 2–4% aluminum, up to 0.05% lead, with the remainder zinc. They have tensile strength of 450–690 MPa (65–100 ksi), yield strength of 170–380 MPa (25–55 ksi), and 10–25% elongation, providing moderate ductility. They have Brinell hardness of 150–200 HB, exhibiting excellent wear resistance. The alloy is stable in severe sea environments, provides low friction, and can withstand high stress. These properties make it a very good option for gears, bearings, heavy marine hardware, and industrial high-load applications where there is a need for durability and reliability.

Select the right manganese bronze bar by considering its strength, corrosion resistance, machinability, and load-bearing capacity. Match these properties to your application's requirements, including environmental conditions and mechanical stresses.
Manganese bronze rods are available in sizes ranging from 1/4" to 8" in diameter. Finishes include mill, polished, ground, and custom, catering to various industrial applications.
Manganese Bronze Bars are available in various configurations, including round bars, hexagonal bars, square bars, rectangular/flat bars, and custom shapes to suit diverse industrial and machining applications.
Manganese Bronze Bars and Rods are highly prized for their strength, wear resistance, and corrosion protection, especially in saltwater conditions. Within marine use, they are employed for propeller shafts, rudder parts, and heavy marine fittings because they can resist permanent contact with seawater. In industrial applications, they are selected for gears, bushings, and bearings requiring high load-carrying capability with low friction. Manganese bronze is utilized by aerospace industries in mission-critical applications for long-term reliability. It is also used in producing heavy-duty equipment, machines, and tools where machinability, strength, and prolonged service life in combination are necessary for best performance.
