With a solid reputation grounded in engineering excellence, unwavering quality, and a focus on customer satisfaction, Rupal Metals offers M2 Steel products that adhere to global standards for durability and performance. Their M2 Steel Bars and Rods are highly regarded for their hardness, wear resistance, and toughness, making them perfect for high-speed cutting tools and other essential components. Rupal Metals proudly serves the tooling, automotive, and manufacturing industries with reliable material solutions.
Manganese Bronze Bars and Rods are primarily made up of copper (55–65%), zinc (20–25%), manganese (up to 4%), aluminum (up to 3%), along with trace amounts of iron and lead. This unique blend results in impressive tensile strength of up to 850 MPa, yield strength around 450 MPa, and elongation rates between 10–20%. Additionally, they boast excellent wear resistance and anti-seizing properties. These bars maintain their strength even under heavy loads, making them perfect for high-speed machining. Manganese Bronze is particularly known for its excellent corrosion resistance, especially in seawater and industrial settings, which makes it a go-to choice for heavy-duty engineering tasks.
