Remaghic Consortium, in which TECNALIA takes part, met to review the progress focused on REE extraction, Mg recycling methodologies and the development of alloying processes. The feedback received from the European Commission was very positive. Now Remaghic needs to keep up with the high expectations!
Magnesium alloys can offer a significant weight reduction when compared to aluminium alloys. Weight reduction is a cross sectorial key design driver. If a superior energy absorption and vibratory behavior is added, magnesium is promising candidate for future application if some of its drawbacks are overcome, such as its cost, manufacturability problems, corrosion and creep behavior and low allowable service temperature.
Addition of Rare Earth Elements (REE) improves the performance of Mg alloys significantly, though a price increase has to be taken into account.
Recovery and recycling technologies combined with a new alloying process will produce low cost Mg+REE alloys.
In order to do this, REE that are usually stockpiled (Ce, La, Y, Gd, Sm…) in favor of the most demanded ones (Nd, Dy) are considered as attractive candidates to lower the price.
TECNALIA is participating in the project REMAGHIC, focused on reducing the dependency of the supply of critical elements (REE and Mg) on sources exterior to the EU and to solving the REE Balance Problem.
REMAGHIC will contribute to the penetration of magnesium alloys in important sectors for the European industry (as Transport, Energy or Biomedicine) and promote the interest of different OEMs on future generations of light structural components of competitive performance (that of primary Mg+REE alloys), low cost (that of primary Mg) and weight reduction (30%).
