Regarding the “Hardness Value” graph on the Patently Apple link you posted, I must point out that relative hardness is only one of a number of performance criteria that must be considered when searching for a suitable material for, say, an i-phone case. Is Glassinickel suitably “transparent” for use with wireless charging technology (for that matter, is LM-105)? Beyond that, how hard does a material need to be for this application, given that LM-105 is itself harder than Stainless Steel. And does hardness equal toughness; glass is very hard but also brittle and shatters when dropped. Just spitballin’ here...
