More info

Magnesium Gadolinium (MgGd) casting alloy is made by melting metal magnesium and metal Gadolinium. The common alloy ratio is 20-70% magnesium, and the ratio can also be customized. The magnesium-based master alloy has a uniform and stable composition, which can meet the requirements of magnesium alloy composition, microstructure regulation, and performance improvement. Our master alloys are produced in adherence to strict quality control practices utilizing an induction melting and alloying process followed by static mold or direct chill (DC) continuous casting. Static cast finished products are available in a variety of forms including full or cut waffle ingot and notch bar ingot. Magnesium Gadolinium (Mg-Gd) Master Alloy master alloys are also available in the shot, screened and sized to specification and in bagged shot.

Magnesium Gadolinium Master Alloy Application

Mg-Gd series alloys: Gd can improve the melting point and creep resistance of magnesium alloys. As early as 1974, researchers discovered that the Mg-Gd alloy that has undergone extrusion, quenching, and tempering and aging treatment has higher tensile strength at both high and low temperatures. Motorbike et al. studied the performance comparison of simple Mg-Gd binary alloys with WE43, QE22, and other alloys, and found that the creep resistance of Mg-Gd alloy is much higher than other alloys, and with the increase of Gd content, the creep resistance increase.
