George Metals, a trusted manufacturer and supplier located in Houston, USA, specializes in high-quality Manganese Bronze Bars and Rods. These products are designed to deliver strength, durability, and resistance to corrosion, making them perfect for tough industrial settings. Known for their remarkable wear resistance, high tensile strength, and excellent machinability, these copper-based alloys are crafted from top-notch raw materials and adhere to strict manufacturing standards, ensuring they maintain dimensional accuracy and structural integrity. Ideal for marine hardware, heavy machinery, aerospace components, and industrial bushings, these bars and rods are essential for achieving optimal performance where reliability and corrosion resistance are paramount.
Manganese Bronze typically consists of 55–65% copper, 20–25% zinc, and 2.5–5% manganese, along with small amounts of aluminum, iron, and lead to boost machinability and strength. This alloy boasts impressive mechanical properties, including tensile strengths ranging from 400–800 MPa and high yield strength, making it perfect for heavy-duty applications. It also offers good impact resistance, fatigue strength, and dimensional stability. Manganese Bronze is resistant to seawater corrosion, brine, and atmospheric oxidation, making it a top choice for harsh and corrosive environments, especially in marine and industrial applications where a long service life is crucial.
