Materials Testing

• Microstructural analysis of ferrous and non-ferrous materials
• Testing of cast and sintered materials
• Testing of welded joints
• Determination of coating thicknesses of all kinds

• Tensile, compression and flexure tests
• Notched bar impact tests
• Hardness tests
• Bolting tests
• Dynamic strength testing

• Iron, aluminum and copper alloys
• Mg-, Ti-, Zn-, Co-, Ni-based materials (*also chip samples and castings)

• Salt spray, climate change, media resistance tests
• Testing for intergranular corrosion (stainless steels, welds)
• Hot light fastness testing, sunlight and climate simulation (e.g. Florida, Arizona, Kalahari) 
• on e.g. metals (ferrous, non-ferrous, stainless steel), coatings, plastics, composites, textiles

• magnetic and magnetic inductive testing methods
• Surface crack testing
• Ultrasonic testing methods
• Endoscopy etc.

• Visualization and assessment of surface topography of fractured surfaces, corrosion and wear phenomena.
• Determination of chem. Elements of residues, deposits and inclusions by means of EDX - analytics
• Examination of conductive and non-conductive samples (e.g. plastics)

Another major subject area of the division comprises the testing of initial samples with regard to their conformity with OEM specifications.

In cooperation with the client, our engineers draw up specific test programs and evaluate the results.

If deviations occur, we can make recommendations for optimization.
