Stainless Steel Frits - Unidense Type

Unidense frits

For both standard frits and those produced to custom specifications, these frits offer unexcelled reproducibility and precision. Proprietary manufacturing processes ensure uniformity and precise, repeatable dimensional control.

Stainless steel frits are manufactured of SS316L, which has extra-low carbon content. The sintering process used results in a strong bonding of the sinter metal particles. Depending on the grade of powder used, the porosity of the frit can be precisely tuned.

NOTES

  • Standard frits are without chamfers - chamfered frits are available on request.
  • Frit volumes are theoretical and are calculated by multiplying overall frit volume times the porosity proportion.
  • Stated frit porosities are only nominal and do not reflect the maximum pore size of a frit.
