Properties

1.Tensile strength of Nickel Celmet

Tensile strength of Nickel Celmet

Tensile strength is proportional to the density of nickel regardless of cell size.

2.Pressure drop of Nickel Celmet

Pressure drop of Nickel Celmet

3.Heat-resistance (Oxidization)

Heat-resistance (Oxidization)

Operating temperature limit:
Ni…450-500 deg, Ni-Cr…650-700 deg

4.Relationship between porosity
  and compression rate

Relationship between porosity and compression rate

Even if you pressed down to half thickness, the porosity is kept at 90%.

5.Properties of dust collection

Properties of dust collection

Even if you use grade No.8 - pore size about 230µm- Celmet whose thickness is 1.4mm, particle of 5µm can be trapped at 50%.

6.Degree of sound absorption
  (Back air layer 300mm)
