Stellite 25/L605 Cobalt Alloy (BS 171D) Certified Reference Material

This Stellite 25 / L605 certified reference material is a cobalt-chromium-tungsten superalloy used as a standard for calibrating and verifying your spectrometer (handheld XRF, benchtop XRF, OES). This material is certified to ISO 17034 with values established through interlaboratory testing, giving you traceable, defensible composition data for calibration checks, instrument verification, and quality control on high-temperature cobalt superalloys used in aerospace and gas turbine applications. For field verification and PMI work, many customers pair this material with NEW or PRE-OWNED handheld XRF analyzers for rapid, on-site analysis.
