ALWA POR ALUMINIUM 3 (500 x 500 x 20 mm)

ALWA POR ALUMINIUM

Here you can see all the advantages of ALWA POR ALUMINIUM at a glance:

  • is made of aluminium and a resin binder.
  • is porous and is produced as a block or slab in our factory in Gronau, Germany.
  • has a surface structure from very smooth to good depending on the pore size and is characterized by a good porosity.
  • is easily machinable and can be polished to a shiny surface.
  • is particularly suitable for thermoforming and other vacuum processing, and is also suitable for
  • hot steam or water steam processing (EPS/EPE/EPP),
  • vacuum clamping and gripper technology,
  • filter applications,
  • air film sliding technology,
  • aeration of aquaria, fish ponds and sewage treatment plants,
  • foundry and many other applications.

Delivery forms: Blocks and slabs are available in different wall thicknesses:

Please consider the different thermal coefficients of linear expansion if ALWA POR ALUMINIUM is screwed on a slab or something is screwed on ALWA POR ALUMINIUM (slab, block or mould). Drill larger holes for the screws into the material, so that the different expansion coefficients can level out. Screw connections which are used several times should be equipped with threaded sleeves.
