NON-DESTRUCTIVE MEASUREMENT OF NON-FERROUS METALS

Electrical conductivity is an extremely important material property that provides information not only about a metal’s ability to conduct electrical currents but also about its composition, micro structure and mechanical properties. Using the SIGMASCOPE® SMP350 and GOLD B, it is easy and quick to determine the electrical conductivity with precision and accuracy.

The SIGMASCOPE® SMP350 and GOLD B measure the electrical conductivity using the phase-sensitive eddy current method, which is approved by both DIN EN 2004-1 and ASTM E 1004 for determining conductivity. This kind of signal evaluation allows for contact-free determination of a substrate’s electrical conductivity, even under paint or plastic coatings up to 500 μm thick. This method also marginalises the influence of surface roughness.

SIGMASCOPE® SMP350

Applications:

The SMP350 can measure the electrical conductivity
of any non-magnetisable metal. Furthermore, since the electrical conductivity provides data about other material properties, it is effective in a wide range of measuring applications and fields of use, including:

  • Quality assurance and sorting of raw materials
  • Authentication of coin alloys (e.g. specific
    conductivity of Euro coins)
  • Assessing hardness and strength of heat-treated materials
  • Inspection of heat damage, material fatigue and cracks
  • Estimating the phosphorous content in copper
  • Tracking precipitation processes, e.g. for Cu-Cr alloys
  • Testing the homogeneity of alloys
  • Scrap metal sorting
Features:
  • Statistical display of significant values such as mean value, standard deviation, min, max and range
  • Manufacturer’s certificate is included in the scope of supply
  • Extremely easy calibration and normalisation procedure
  • Measurement in “continuous display mode” for running a scan over a region of a surface.
  • Easily interchangeable units of measurement (MS/m or %IACS)
  • Measurement range: 0.5 – 65 MS/m or
    1 – 112% IACS
  • USB interface for data exporting together with a PC software is included
  • Measurements pursuant to ASTM E 1004 and DIN EN 2004-1
  • SMP350 fulfills Boeing specification BAC 5651

SIGMASCOPE® GOLD B & C

In recent years the price of gold and other precious metals has skyrocketed, making the purity of these valuable components the most important attribute of any precious metal product. Adulterated or fraudulent alloys of high value coins or bullion can lead to considerable monetary losses. The only way to rule out such risks is to test the items using trusted analytical methods.

Applications:

Precious metal alloys and fine gold all differ in their electrical conductivity, making this physical dimension ideal for material analysis of bullion and coins. In just a few seconds the SIGMASCOPE GOLD can determine the conductivity of a sample with an unmatched precision:

  • Quality assurance and sorting of gold bullion bars
  • Authentication of gold bullion alloys 
  • Assessing hardness and strength of gold bullion bars
  • Testing the homogeneity of gold bullion bars
Features:
  • Statistical display of significant values such as mean value, standard deviation, min, max and range
  • Manufacturer’s certificate is included in the scope of supply
  • Extremely easy calibration and normalisation procedure
  • Measurement in “continuous display mode” for running a scan over a region of a surface.
  • Easily interchangeable units of measurement (MS/m or %IACS)
  • Measurement range: 0.5 – 65 MS/m or
    1 – 112% IACS
  • USB interface for data exporting together with a PC software is included
