Chemical analysis and mechanical tests of metallic materials

Let’s evaluate the material you’re using together.
Companies often need to validate the supply of incoming materials or check outgoing materials after processing. Our support service partners companies in the certification of their products and processes, through carefully-controlled laboratory techniques.
Materials characterisation generally involves carrying out chemical analyses and mechanical tests appropriate to the intended field of application.

CHEMICAL ANALYSIS
The chemical composition of metal alloys (steels, cast irons, aluminium alloys, copper, brass, bronze) is often the starting point – and sometimes an essential activity – for correctly classifying the material. Our laboratory offers a complete suite of chemical analysis services with a full range of different inspection techniques:

  • Quantometric solid-state chemical analysis using Optical Emission Spectroscopy (OES)
  • Wet chemistry analysis using Plasma Emission Spectrometry (ICP)
  • Elemental analysis of carbon and sulphur
  • Determination of gases such as O, N, H, using specific determinators.

Traditional chemical analyses are accompanied by qualitative determination of the composition of deposits – corrosion products, fragments, inclusions and particles of an unknown nature – by means of spectroscopy techniques conducted using a scanning electron microscope (SEM-EDS)

MECHANICAL TESTS
These are generally required in applications of a structural nature but can also be used as a means of controlling quality for processes and products in any industrial areas.

These tests compare the results obtained with the reference standards in order to evaluate the mechanical conformity of the tested materials. These are utilised, among other things, to evaluate the correct execution of heat treatments, inspecting and verifying welding processes and welder competence.

Mechanical tests include:

  • Tensile testing (cylindrical and flat)
  • Load and compression testing
  • Bend testing
  • Impact testing (at room temperature and at low temperatures)
  • Hardness and microhardness testing.

The preparation of the specimens for the mechanical tests takes place in the workshop within our laboratory.
