Apple have filed for a patent to create “enclosures” for its devices out of “hardened” gold. The products would be included on most Apple devices including iPhones, iPads, MacBooks, etc.
Apple’s new idea is to turn gold alloys into crystalline form by mixing it with other metals. The special process involves rolling, heating, cooling and aging, the patent application, titled ‘Crystalline Gold Alloys with Improved Hardness’, said. The method could also be applied to process 24-karat gold and the coating can differ from yellow gold to red gold, to even green, blue, or purple gold.
“The disclosure provides gold alloys with improved yield strength and improved hardness,” the application said. “With such an improved hardness, the gold alloys can have very good scratch resistance and improved durability for use as enclosures for electronic devices.”
However, as with all our stories about patent filings, this patent does not mean that we might actually see a gold-coated iPhone X anytime soon. Only a few of Apple’s patents make it to production or even development stages.
But there is hope, as the new iPhone X is available for pre-order only in “Silver” and “Space Grey,” leaving gold and rose gold options up in the air.
Gold plating your mobile device is expensive, with spot gold last seen trading at $1,270.70 per ounce, down 0.20% on the day, according to Kitco.com. For example, prices for 24-karat gold iPhone 6 on Gold & Co., a luxury jeweler, vary from $5,000 to $130,000.
