Trace Metals

Alcoa Trace Metal Standards supplement our regular alloy standards and are made with 99.999% pure aluminum. A unique method for trace metal additions allows alloys to be produced with highly controlled trace metal concentrations. Trace metal concentrations have been picked to provide both low end calibration points (<0.0001%) and levels that are typical for trace metal content. Actual concentrations may vary from those shown in the catalog, but will always be certified using a combination of analytical techniques including Optical Emission Spectroscopy, Inductively Coupled Plasma, Glow Discharge Mass Spectroscopy and other appropriate techniques.
 
Standards designated by the prefix “ST” contain trace elements in a matrix similar to the specific alloy family indicated within the “ST” designation, e.g. ST1-1050.
