Magnesium Sand Castings

Key Benefits

 Light Weight
 Stiffness
 Damping Capacity
 Dimensional Stability



     Our magnesium castings are used for their light weight, stiffness, damping capacity, and dimensional stability. Parts we produce include automotive prototypes, robotic parts, medical equipment, machinery, racing, space, aircraft engine components, helicopter gear boxes, test equipment, sports equipment, etc...

    For magnesium automotive prototypes, we have the ability to take your part file to an SLA model to pattern and rapid prototype castings.


The most common alloys poured at Yankee Magcast are as follows:
