Manganin Resistance Wire – Precision Alloy for Stable Electrical Performance
(Including Grades 6J13 / 6J8 / 6J12)
Introduction:
Manganin wire is a specialized copper-manganese-nickel alloy renowned for its extremely stable electrical resistance and low temperature coefficient of resistance (TCR).
It is widely used in precision electrical applications where high accuracy, long-term stability, and minimal thermal drift are essential.
Grades such as 6J13, 6J8, and 6J12 represent variations of Manganin alloy, each optimized to meet different technical demands.
Key Features:
Ultra-Stable Resistivity: Very little change in resistance with temperature or time.
Low TCR: Guarantees consistent performance in varying thermal conditions.
Excellent Long-Term Stability: Ideal for precision instruments and metrology applications.
Good Corrosion Resistance: Reliable performance in humid and harsh environments.
Good Solderability and Workability: Easy to process into wires, ribbons, and foils.
Applications:
Precision resistors
Standard resistors for laboratories
Shunt resistors for current measurement
Electrical measuring instruments
Strain gauges
Precision compensation components
