LINQCELL NWM 250 | 0.25mm Nickel Wire Mesh


Main features
  • 0.25 mm wire diameter
  • Excellent chemical stability and anti-corrosion resistance
  • High electrical conductivity

Product Description

LINQCELL NWM250 is a finely woven wire mesh made from high-purity nickel alloy, with a wire diameter of 0.25 mm and a nickel content of at least 99.9%. Its mesh size and uniformity complies with GB/T 17492. This mesh offers excellent electrical conductivity, chemical stability, corrosion resistance, and mechanical durability. Its versatile properties make NWM250 suitable for different electrochemical devices, including water electrolyzers, fuel cells, and batteries, such as nickel–metal hydride (NiMH) and nickel–cadmium (NiCd) batteries.

Key Features:

  • High corrosion resistance
  • Very low impurities
  • Cheaper and more cost efficient than sintered titanium

In water electrolyzers and fuel cells, LINQCELL NWM250 can be used both as a gas diffusion layer, facilitating mass and electron transfer within the device, and gas diffusion electrode when catalyst layers are directly applied to it. Its suitability for alkaline systems has established it as a standard electrode material in alkaline water electrolyzers.

Highly Recommended for:

LINQCELL NWM250 comes in different mesh counts (30, 40, 46, and 60, allowing precise tuning of diffusivity to meet various device design requirements. It is also available in two Ni grades: N4 (Ni201), and N6 (Ni200).

Mechanical Properties
Elongation
Elongation
Elongation is the process of lengthening something.

It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks.

It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
 27–28 %
Tensile Strength
Tensile Strength
The tensile strength of a material is the maximum amount of tensile stress that it can withstand while being stretched or pulled before failure.

Some materials break very sharply, without plastic deformation, in what is called a brittle failure. Others, which are more ductile, including most metals, experience some plastic deformation and possibly necking before fracture.
Tensile Strength
Tensile Strength
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture.

To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.
