How Apple Will Make Superhard “Apple Gold” for Its Watches

Apple design VP Jony I ve tell the Financial Times that Apple had invented a unexampled kind of radical - hard 18 karat amber for its line of luxury Apple Watches . Though hearsay about the gold ’s bizarre molecular bodily structure are false , Apple Gold is a real affair . Here ’s what the patent break about it , and a potential Apple Diamond as well .

Financial Times author Nick Foulkes wrotethat “ the molecules in Apple Gold are closer together , ” whichArs Technica ’s Jonathan Gitlin dismissed(rightly ) as absurd . But Apple amber is undeniably harder than veritable 18 KiB gold . We looked ata patent program filed by Apple industrial designerslast class for a “ method acting and apparatus for forming a gilded alloy matrix composite plant . ” It describe several processes for making hard atomic number 79 .

Apple Gold is made using a extra process that involve blending gold powder with ceramic pulverization , then heating and compressing it , to create a centre that ’s grueling and more scratch resistant than regular gold .

That said , “ ceramic ” does n’t quite cover what Apple will be using . In the patent of invention , the fabric number load out over two lines . Your Apple amber could be merge with “ boron carbide , diamond , cubic atomic number 5 nitride , titanium nitride ( TiN ) , iron aluminium silicate ( garnet ) , silicon carbide , aluminium nitride , aluminum oxide , sapphire powder , yttrium oxide , zirconia and tungsten carbide . ”

The patent describes several possible ways that the ship’s company might be melding ceramic and metallic element . One include making a holey ceramic “ preform ” that will be fulfill in with a “ amber web ” to create the ceramic and metallic element matrix . basically , metallurgical engineer would make a level of ceramic and then squirt the amber into it , so that the golden molecules tuck themselves between molecules in the ceramic . ( This might be the unconscious process that led to the weird verbal description in the Financial Times . ) The textile would be compact and heated in a process called sintering until the metal and ceramic became a upstanding mass .

In the sum-up share of the patent of invention , we listen about another method by which Apple look at making the watch case . After coating ceramic subatomic particle with gold , they could identify “ the atomic number 79 and ceramic smorgasbord into a dice having a close final shape . The method acting to boot includes compressing and heating the atomic number 79 and ceramic mixture in the dice forming a golden metal matrix composite having a build fit to the near nett shape . ”

This process is called dice - striking , and it ’s a common way to increase the hardiness of jewelry . A metal is placed into a mould , and compressed to increase its density and hardness . The cognitive process come its name from the “ die , ” the grave , pulley-block - alike mold used to press the metallic element into its close together shape . Note that the shape make probably wo n’t be its final condition . After the metal is made ready , it ’s not unusual for it to be bent into a in effect shape , or detail .

Another method in the patent describes using a “ wet agent ” to cover diamond particles , then append gold and compressing the entire affair . The wetting federal agent forms a carbide at the moulding between baseball diamond and amber that binds them together . In other word , this patent of invention for Apple Gold suggests that the company is also mulling over the idea of make watch whose alloy is a portmanteau of gold and diamond .

Though this all sounds fairly futurist , the cloth that Apple describes here soundsawfully interchangeable to a scratch - resistant 18 k gold watchthat Swiss manufacturer Hublot created back in 2011 . Hublot also made their“Magic Gold”with ceramic , though they did n’t use die excise in their method acting .

The point is that Apple is using somewhat common technique in the jewellery industry . Gold and ball field are also used in a lot of stuff science practical app , too — but usually you ’d rule them in microprocessor chip or industrial element . What ’s Modern is that Apple figuring out how to use metallurgy and material science to generate even more extreme shape of luxury .

Is Apple Gold stronger than even Au ? for sure . And Apple ’s gold / diamond material will be solid too . But still , Apple Gold is n’t really about pass water something that ’s functional . It ’s about selling something that symbolize both cutting - edge scientific discipline and wealth at the same clock time .
