Description
Reviews (0)

Karma Resistance Wire, also known as 6J22 alloy wire, belongs to nickel-chromium-aluminum-iron precision resistance alloy. This material maintains stable resistance value under wide temperature range, with tiny thermal EMF against copper, outstanding creep resistance and anti-aging property.
It can keep consistent electrical performance even under long time load and temperature fluctuation. Compared with conventional constantan wire, Karma resistance wire has much lower temperature coefficient, which satisfies high-precision electronic component requirements.
Available in various wire diameters, spool packaging, customized size on request. Typical applications include high precision resistors, strain gauges, aerospace electronic modules, measuring instruments, sensors and precision control equipment.
