'liquid metal' sounds cool. It's probably a metallic glass. I super dislike that it seemingly will be synonymous with the brand name by Apple even though that stuff has been around for decades.

Not that there are particularly many places where this is used - mostly because it really is just very expensive. In the awesome position that Apple is in, economic feasibility is so much easier to achieve, with like tens of millions of guaranteed parts to be preduced.

It's not metallic glass. It's an injectable, super strong alloy. You can manufacture things like you're using injection molded plastic.

To be honest, British also has an injectable stainless steel, but its application domain is much more different.
