Magnesium machined parts are weight resistant, so they are also popular in consumer electronics, robotics, medical equipment …
General characteristics of MAGNESIUM alloys
- 30% to 35% lighter than aluminum,
- It offers an excellent combination of mechanical properties,
- Easily machinable – Fire prevention measures are however recommended when machining this material.
- 3 times more resistant than polymers,
- Thermal conductivity relatively high.
- Alloys and in particular those with zinc, zirconium and thorium keep a relatively high thermal conductivity which favors hot uses.
