Each metal alloy has a different composition which gives it properties combining those of its constituents. Therefore, alloys have specific properties and well-defined fields of use.
Indeed, the contents of the constituent elements of the alloys determine the different characteristics of a material such as its hardness, its melting point, its potential corrosion etc… and are thus capital parameters to be taken into account.
Thus, the control of an alloy makes it possible to ensure that the alloy used is adapted to the field of application and to avoid the risks of failures (corrosion, rupture, surface defect?).
