Automotive magnesium alloy
The life of the die can be greatly extended when compared to die casting of aluminum. This is due to the heat transmission properties of magnesium and its decreased affinity for iron, which leads to negligible soldering and less erosion.
Company Profile
Minghe is a global, full-service manufacturer of precision die casting products. With more than 35 years' experience in research & development, manufacturing, and precision machining for the aluminum,zinc and magnesium die casting industry, we are proud to work with some of the world's top automotive, engineering, electronics, and telecommunications companies.
We provide experienced engineering, technical management, and quality assurance teams ready to support the most challenging projects. We have assisted clients with precision machined prototypes, die design, extensive product testing, and volume manufacturing.
Considerations of Magnesium Alloy Die Casting Production
Die Life
Compared to die casting of aluminium, the die life of can be significantly improved. This is because of the heat transfer characteristic and the reduced affinity with iron of magnesium, resulting in negligible soldering and reduced erosion.
Productivity
Because the heat content of magnesium is lower than aluminium, the metal solidifies at a faster rate, generates shorter cycle times, typically by 15-25%. Exceptional dimensional stability of the as-cast product is a particular characteristic of cast magnesium alloys. Frequently, annealing or stress relieving treatments are not required with magnesium, contrary to experiences with some cast aluminium components where some growth continues as natural ageing effects occur over extended times at moderate to elevated temperatures. Machinability is outstanding, exhibiting the best characteristics of all the structural materials viz reduced machining time, lower power requirements, longer tool life, excellent surface finish frequently with a single cut and minimal tool build-up with lower overall machining costs.
Sensitivities
During the die casting cycle each part of the casting will develop a microstructure governed by the local solidification rate and pattern. Correct design of the casting and its feeding system are essential to ensure a uniform and directional solidification pattern. Where this is not achieved, it is to be expected that a certain fraction of microporosity will form due to volume contraction during solidification. This will inhibit the achievement of the excellent properties attainable in die cast magnesium. Ductility is a significant process-sensitive parameter with the control of inhomogeneities, defects and process of paramount importance in realising the potential for structural applications.
