Introduction

Nichrome wire mesh, also known as NiCr Mesh, nickel-chromium wire mesh, or chromium-nickel wire mesh is a family of alloys of nickel, chromium, and often iron, and possibly other elements. Nichrome alloy wire & mesh is commonly used as resistance wire, heating elements in things like toasters and heaters, and a few other related applications.

A common nichrome alloy wire mesh is 80/20 Ni Cr wire mesh， NiCr80 20 wire mesh, or Cr20Ni80 wire mesh, which is of 80% nickel and 20% chromium by mass.
Besides 80/20 NiCr wire mesh, there are many other combinations of metals for various applications.
