The high demand for aluminum alloys and the growing pressure to reduce their weight creates enormous market potential and encourages innovation in this area. The CastQC project focuses on a new alloy with a non-equilibrium quasi-crystalline (QC) phase that has 30% higher mechanical properties than the commercial EN AC-46000 (DIN 226) alloy and requires 30% less aluminum to achieve the same functionality and subsequently generates 20% less CO2 emissions. The main goal of the CastQC project is to reach TRL 8 and enter the market with a new QC alloy that will (partially) replace commercial Al-alloys, steels or even some Ti and Mg alloys. The QC alloy will bridge the gap in market demand for lightweight materials in the field of e-mobility and contribute to increasing the competitiveness of the European automotive industry.
