Spectrographic Analysis for Investment Castings

Feb 13, 2018


Spectrographic analysis of investment castings is a non-destructive test that detects the wavelengths of elements in an alloy. A small sample is heated to produce vapor that can be analyzed. This enables foundries to accurately determine how much of each metal is present and achieve precise control of alloy composition. This is especially important when exact compositions are required to achieve specific characteristic for highly specialized applications.
