Highlighting it shows that Apple is constantly doing R&D on melting molding recycling all types of metals.

Apple will use low melt point metal to reinforce its ‘thin walled devices’ so they can cnc or water jet them or whatever without damaging them. but Apple can't use this on existing crystalline aluminium, because if they could have made the relatively softer non-amorphous aluminum thinner they would have already done so, the most likely candidate for the new “thin walled devices” patent is one made out of bmg metals.

i just highlighted that to emphasis the point that it is most likely for bmg alloys.
maybe used to reinforce the AppleWatch while the back is cut out for the sapphire/zirconia back... possible :)
