Aluminum Certified Reference Material for Trace Metal Analysis of Alloy 1050, ST1-1050

Arconic Spectrochemical Reference Materials, located at the Arconic Technology Center near Pittsburgh, Pennsylvania has been producing certified reference materials (CRMs) and reference materials (RMs) for the aluminum industry for more than 70 years. Our CRMs are widely recognized for their uniformity and accuracy of certification. Arconic CRMs and RMs are typically used for calibration, drift correction, quality assurance, and method validation for Spark-AES instrumentation used by the aluminum industry to verify the composition of aluminum and aluminum alloys. We maintain a large inventory of CRMs and RMs consisting of more than 300 alloy compositions targeted to meet the needs of the aluminum industry. Arconic Spectrochemical Reference Materials holds accreditations for the following ISO standards: Guide 34:2009, 17025:2005, and 9001:2008. Arconic Trace Metal CRMs supplement our regular alloy CRMs. 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 points that are typical for trace metal content that can be measured with good precision and accuracy by today’s instrumentation. Actual concentrations may vary from those shown in the our catalog, but will always be certified using a combination of analytical techniques including Spark-AES, ICP-AES, GD-MS, ICP-MS and other appropriate techniques. CRMs 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.
