Friedrich Eisenkolb Accredited Testing Laboratory

Competent, fast and flexible

More than 60 years ago, our eponym, Prof. Friedrich Eisenkolb, laid the foundation for our powder-metallurgical test laboratory in Thale, Germany. We carry out physical, mechanical-technological and analytical testing at metallic and powder metallurgical materials as well as testing of metal powder and testing of technical cleanliness.

Our team of 9 employees guarantees technical competence at the highest level and ensures promptness and flexibility for the solution of complex material-testing tasks.

Our laboratory is a certified training organization for material inspectors.
