Hydrogen Measurements Comparison in EN-AW 5083 Alloy

The automotive sector is particularly important for the aluminium industry, and the E mobility will strengthen this trend because the need for even lighter construction will become more important. Quality requirements for the material are, therefore, becoming more important. For this study, billets of alloy EN AW-5083 were cast in the R&D casting pit at the TRIMET site in Essen. The hydrogen content in the molten aluminium was measured using, Hycal and Reduce Pressure Test devices. To test the hydrogen content in solid form, samples were taken from the billets and tested with a Leco RHEN 602 Hydrogen instrument. The purpose of the measurements was to compare the results of the readings and to investigate the influence of the casting parameters on the hydrogen content.
