Electrical Conductivity measurements in non ferromagnetic metals

Eddy Current Conductivity Meters provide a simple and immediate way to obtain the precise conductivity of non-magnetic samples.
Other methods require laborious specimen preparation, careful dimensional measurements, expensive instruments and strict laboratory conditions. Proper measurements could take hours.
With the ZAPPITEC 12Z Eddy Current Conductivity meter you will achieve a superior degree of precision in seconds. Check out our article on how to measure electrical conductivity of aluminium alloys.

Non-destructive alloy sorting by conductivity

Alloys with different compositions usually have a different Electrical Conductivity. This allows for a very quick and convenient method of sorting alloys based on this property. Alternative solutions are either destructive, expensive or require chemical analysis. If you need to automatically sort serialized parts check out our ZAPPITEC Eddy Current Conductivity Meter model 12A for automated sorting.

Thermal treatment evaluation in Copper-Chromium, Copper-Zirconium and Aluminium alloys

Some alloys, notably Aluminium alloys, can be thermally treated to achieve special mechanical properties. In many cases the conductivity of such alloys changes during heat treatment, allowing for a convenient way to monitor the heat treatment process.

Heat damage determination in Aluminium alloys, used in the Aerospace industry

Some aluminium alloys suffer from degradation of mechanical properties when exposed to high temperatures. This is also accompanied by a change in conductivity. By controlling the conductivity of critical parts which could be exposed to fire or high temperatures it is possible to determine if the part needs replacement.

Quality control of raw materials by evaluation of purity for copper, silver, gold, aluminium

The picture above shows very strong conductivity influence of minor impurity concentration in Copper ETP. Similar behavior is observed in all high conductivity metals (copper, silver, gold, aluminium) allowing for a very effective quality control method when testing pure metals.

Thermal Conductivity vs Electrical Conductivity in metals

Did you know you can use our conductivity meters to evaluate thermal conductivity of metals? The Thermal Conductivity of metals is approximately proportional to the Electrical Conductivity. By measuring the Electrical Conductivity the Thermal Conductivity can be easily found, as shown in the graph above.
