A certificate tells you what the mill claims. A spectrometer tells you what the metal is. We verify incoming stock chemistry before it reaches a machine — which matters most for alloys whose performance depends on composition, such as Kovar and Permalloy.
Incoming stock is verified on our benchtop spectrometer against the specified grade and EN/DIN number.
Kovar's expansion behavior and Permalloy's permeability both depend on composition — a drift that is trivial elsewhere changes performance here.
Verification means the certificate in your file matches the material in your part.
Real capability windows — verified in-house, not estimated.
