Rio Tinto ALCAN Quality

Rio Tinto Alcan spectrochemical standards are not derived from production material. They are produced from a direct-chill continuous casting process.   Although this method of manufacture is expensive, it ensures that each continuous-cast disk exhibits excellent homogeneity.  This provides reliable results for the analysis of both  simple and complex aluminum alloys.

Each lot undergoes extensive homogeneity testing, and  every element to be certified is then analyzed using the most widely recognized methods.  Each sample is analyzed in duplicate by two technicians using two different analytical techniques that include ICP, AA, X-Ray fluorescence, colorimetric, fluorimetric, and titrimetric methods.  The individual values reported are statistically evaluated, and the mean values are compared to the results obtained by Optical Emission Spectrometry.  Finally, the check samples are circulated among other Rio Tinto Alcan laboratories for verification.  These laboratories perform their own chemical analysis and report their results to the Arvida Research Center.  Worldwide comparison analysis involving top specialists in the field ensures high confidence in the values obtained.
