Apple could release a line of products made from Liquidmetal in the near future, a patent filing suggests.
The document uncovered by Electronista indicates that the Cupertino firm may have mastered a technique for creating iPhone and iPad devices coated in the material.
The patent - awarded to Crucible Intellectual Property, a joint venture between Apple and Liquidmetal Technologies - describes a range of factory methods for producing slender sheets of metallic glass for use in a range of tech products.
Moreover, the paperwork specifically mentions that the manufacturing technique was devised to aid the production of new iPhones, iPad, watches and "any electronic device known the art".
Liquidmetal, which uses an alloy of zirconium, titanium, nickel, copper and other metals, could also be used to make hardware more durable, but with the lightness of plastic and an outer surface that is smooth like liquid.
Apple has used the alloy in the past to create SIM card ejectors for previous models of the iPhone.
