Product Description

                                                                                       What is NiFe70
This wire is sometimes erroneously known as NiFe30 wire. Nickel wires should always be known by their Nickel content. The nickel content of this wire is 70%. Hence NiFe70.

Nickel-Iron Alloy is characterised by very low resistivity and high temperature coefficient of resistance. It is widely used in various heaters.

It can automatically control temperature and adjust power by keeping constant current limiting current.

In modern times it has found popularity in the vaping industry due to its high heat and electrical resistance.
