“Back in 2010, Apple signed an exclusive agreement with Caltech spinoff Liquidmetal Technologies, providing Apple with the rights to use Liquidmetal’s advanced metal alloys for consumer electronics purposes,” Eric Slivka reports for MacRumors. “Liquidmetal’s amorphous metal alloys or bulk metallic glasses posses a number of characteristic properties such as high strength and corrosion resistance while remaining relatively light and able to be cast into a variety of forms.”

“Apple quietly tested Liquidmetal’s alloys in the SIM card eject tool for the iPhone 3G, but the materials have otherwise not been confirmed to have appeared in any other Apple products,” Slivka reports. “Evidence of Apple’s continued interest with Liquidmetal alloys has surfaced a number of times over the past several years, including in a granted patent from July covering a process for mass producing thin sheets of the Liquidmetal alloys and a series of technical patent applications published in November describing methods of working with the alloys to create products.”

“A number of patent applications addressing additional innovations with Liquidmetal alloys have been published since that time, including a batch of 17 applications published just this past Thursday,” Slivka reports. “All of these patent applications were filed in June or July of 2012, suggesting that Apple may have made significant progress on these disclosed inventions since that time.”
