Flattened Expanded Nickel-Chromium Alloy Mesh

Ni80Cr20 is alloy of 80% nickel and 20% chromium by weight. Nichrome Mesh is a name for a nickel-chromium alloy mesh. Nickel Chromium Alloy Mesh is corrosion resistant, and has a high melting point of about 1400ºC(2552ºF). Meanwhile, it is relatively high resistivity and resistance to oxidation at high temperatures.

Nickel Chromium Expanded Mesh --- Types:

Flattened Expanded Mesh:
Flattened Expanded Mesh is produced by passing standard mesh through heavy rolls that flatten the strands and bridges to provide an overall level surface. This process, which reduces the original thickness by approximately one gauge, delivers a product particularly suited to applications where a slid able surface is required.

Advantages of Expanded Mesh Sheet:

1.Expanded metal permits free flow of light, heat, sound and air
2.Expanded metal is available in a variety of mesh configurations including diamond, square, round, hexagonal plus architectural and decorative patterns
3.Expanded Metal is easily fabricated, finished, installed and formed
