A single manufacturer can produce hundreds of different metals and alloys for customers. These customers rely on manufacturers to meet specifications for chemical and physical requirements such as heat resistance, corrosion resistance, strength and workability. X-ray fluorescence (XRF) technology is an essential inspection tool that helps with this process. For instance, positive material identification (PMI) using XRF is common in alloy production, fabrication, verification and research activities. Inspectors often use handheld or benchtop XRF instruments to evaluate the composition of parts on-site with accurate, timely results. They can use these precise results to guide all aspects of the alloy manufacturing process, from verifying incoming materials prefabrication, to melting/casting, to quality inspection during important points in the process, including final inspection. With an accurate chemical composition, the user can provide distinct traceability of the part itself or within a material lot, helping to strengthen corresponding quality records. Effectively using XRF in maintenance activities such as PMI can help minimize issues like quality system breaches and material mix-ups.
