SIKA-R...AX filter elements are manufactured by co-axial pressing. A wide range of different geometries can be obtained by means of this pressing process. The pore size is made to measure from 0.5 µm to 200 µm. Sintering turns SIKA-R...AX elements into dimensionally stable, metallically strong components which can be used as self-supporting constructional elements. The pores are fixed in terms of size and position. A special production technique allows the joining between porous and solid materials in a compacting process, resulting in so-called filter modules.

Chemical Resistance and Thermal Stability

As a general rule, the chemical and thermal characteristics of sinter metals are the same as those of the solid materials used. However, the size of the specific surface area should be taken into account when assessing the chemical properties of any high-porosity component (sinter metal).

SIKA-R...AX is manufactured from the following materials:

  • Stainless steels 1.4404 (AISI 316 L / B), 1.4306 (AISI 304 L), 1.4539
  • Titanium
  • Monel
  • Inconel 600 / 625
  • Hastelloy C 22, C 276 and X
  • Special materials
