About this file
This document is a technical reference table containing minimum detection limits for elemental analysis across nine different metal alloy bases: Aluminum (Al), Cobalt (Co), Copper (Cu), Iron (Fe), Iron Arc (Fe arc), Nickel (Ni), Nickel Arc (Ni arc), Titanium (Ti), and Titanium Arc (Ti arc).
Each alloy base section lists detected elements with corresponding minimum concentration (MinCon) and maximum concentration (MaxCon) values, expressed in percentage or parts per million. For example, the Aluminum alloy table identifies 27 detectable elements ranging from Silicon (0.007-42.4) to Zirconium (0.002-0.38). The Cobalt alloy section tracks 15 elements with Tantalum showing the highest minimum detection limit at 0.11. The Copper alloy table monitors 21 elements with Beryllium at the lowest minimum detection of 0.0001. Iron-based alloys include both conventional and arc processing variants, with the arc versions tracking specialty elements such as Tantalum, Hafnium, and Rhenium. Titanium and Titanium Arc sections similarly list detection limits for titanium alloys, including rare earth and refractory metal trace elements. The document serves as a specification or calibration reference for elemental composition testing and quality assurance protocols in metallurgical analysis.
