Introduction

Karma is an improved type of  electrical resistance alloy.

Character

l    Wide range of work temperature

l    Good mechanical processing performance

l    Karma alloy wire made up of chromium, nickel, aluminum  andiron

l    Resistivity is 2 to 3 times higher than manganin

l    Lower temperature coefficient of resistance(TCR), lower  thermalEMF versus copper, good permanence of resistance for long period  oftime and strong anti-oxidation

l    Working temperature range is wider than manganin

l    Suitable for making fine precision resistance elements  andstrain

Application

Miniature high resistance precision wire-wound  resistors in instrument, precision resistor, slide resistor, precision resistor,  standard resistor,self-compensating resistance strain  gage wire grid in temperature below 400 degree centigrade, special resistance  components that is vibration resistance, impact resistance, corrosion  resistance, radiation resistance
