Ny tariby Nickel-Chrome dia be mpampiasa ho toy ny firaka avo fanoherana ho an'ny fanafanana herinaratra sy ny tariby-fetra resistors amin'ny metallurgical indostria, simika sy ny orinasa elektrika, sns.
Ity tariby firaka ity dia manana coefficient fanoherana elektrika avo kokoa, tsara anti-oxidation sy anti-corrosion performance, ary manana workability tsara sy weldability koa izy, miaraka amin'ny hery avo amin'ny hafanana avo.
