Optionally with modification of mechanical, electrical, thermal, chemical, optical, haptic, biological and other material properties.

New class of materials with great potential


Open-pored aluminium casting with novel properties

New class of materials for mechanical, acoustic, thermal, structural and decorative applications.




Unique material

Optionally with modified material properties

There are a variety of different methods for producing open-pored aluminum structures.

Open-pored aluminum casting differs from all known technologies and offers in comparison functional, qualitative and economic advantages in many applications.

The material is available in industrial quantities in almost every shape and size, also partially porous or in composite material.

More than 400 customers in 12 countries are already using it in their first application areas .

Modification, microstructuring and activation of light metal surfaces in the modern METAKER® Surface process result in new gradient materials with new mechanical, chemical, electrical, thermal, optical, haptic, biological and other material properties.

Simple, high-performance series processes and many adjustable material properties put creative engineers in a new paradigm, opening up previously unthinkable innovation potential and completely new, sometimes unexpected, fields of application.

The world's first series application of modified, open-pored aluminum casting was implemented in 2016 in the field of exhaust gas treatment. Many more applications will follow.
