Materials & price
The four house materials, and every line the price is built from.
Four house materials.
The catalogue lists the materials Alef prices today. Find one by what your joint needs, then nest your parts on it.
Filter by temperature, pressure, medium, approval and thickness. Each material page leads into the configurator with the material already chosen, and sheet stock can be bought by the piece.
Temperature, pressure and media data are indicative and do not assure suitability for a particular application. Safety-critical uses need a separate assessment. For other materials, write to us.

Every line of the price.
Alef shows how the price comes about before you order, not after.
Material is charged on the plate area your parts claim, times a waste factor taken from the real utilisation. Add pieces that fill the plate, and the factor and the price per piece usually fall; Alef shows that as it happens.
The browser sends positions, never amounts. The server prices them again with the same engine your preview came from; if the figures ever differ, Alef shows both instead of charging silently.
