Football helmets, motorcycle helmets, car body parts, M16 stock/receiver. None of them have magnesium. Plastics have many advantage over metal. Thermodynamically more stable. Light, strong and they have give. Tooling and material expenses drastically lower.

Carbon fiber would be even better, but that's another subject.

The key is that plastics "have give." This is not what you want in the frame of a camera where precision is measured in microns. Magnesium alloy is used for its greater rigidity. Flexure is a bad thing in a camera body.
