उत्पाद विवरण
CuMn12Ni Precision Manganin Alloy Thick Wire 1.5mm for Instruments & Meters
CuMn12Ni manganin wire (1.5mm diameter) from Huona New Material is a high-stability copper-manganese-nickel alloy wire with a bright, uniform surface finish. Composed of Cu (balance) + 11.0-13.0% Mn + 1.5-2.5% Ni with trace stabilizing elements, it is produced via vacuum smelting, hot rolling, multi-pass drawing, and precision annealing.
Standard Designations & Material Foundation
- Alloy Grade: CuMn12Ni
- International Equivalents: UNS C18600, DIN 2.0880, JIS C1860, GB/T 3131-2019 (Mn12Ni)
- Diameter: 1.5mm (±0.01mm); soft/half-hard/hard temper available
- Chemical Composition (wt%): Mn: 11.0-13.0%; Ni: 1.5-2.5%; Cu: balance; Fe ≤0.3%; Pb ≤0.05%; C ≤0.1%
- Compliant Standards: ASTM B124, EN 13602, GB/T 3131-2019, RoHS 2.0
- Manufacturer: Huona New Material, certified to ISO 9001 and ISO 14001
Key Performance Advantages
Ultra-Stable Electrical Performance
