Magnesium alloys are 2.5x lighter

what I want from Pentax:

a strong yet light "titanium" body like Fujifilm X Pro 3 or an aluminum body like K01 to keep the weight much lighter than stainless steel.

Magnesium alloys are ideal material for shaping of Hi-end camera bodies, best in terms of overall cost, manufacturing complexity and overall performance of the finished product.

Titanium not so; manufacturing processes are more complex and expensive. Titanium was used sometimes back in the past, for simpler camera bodies, when the use of magnesium alloys and casting processes were not quite developed yet.

Magnesium alloys are incredibly light, perfectly suited to reduce camera weight; resulting alloys weigh around 1.8 g per cubic centimetre; they are the lightest of all structural metals. Compare that to approx. 4.5 g weight per cubic centimetre for Titanium: Magnesium alloys are ~ 2.5 times lighter.
