Manganin® Spherical Powder

Manganin® Spherical Powder, a copper–manganese–nickel alloy in finely atomized spherical form, offers excellent flowability, uniform particle distribution, and high sinterability, making it suitable for powder metallurgy and additive manufacturing. Its inherent low temperature coefficient of resistance and electrical stability carry over into powder-processed components, enabling the production of reliable resistive and damping materials. Industries including electronics, advanced manufacturing, and precision engineering employ Manganin® Spherical Powder for creating shunt resistors, damping elements, and high-pressure sensing devices. Specific applications include the fabrication of porous damping structures for vibration control, precision electrical components via sintering, and advanced material research for dynamic stress sensing. Research demonstrates its use in porous damping alloys with high-frequency energy absorption and mechanical robustness, underscoring its adaptability in both scientific and industrial innovation. Manganin® Spherical Powder is therefore a vital enabler of next-generation resistive and damping materials across high-performance fields.
