In the market for an iPhone? Here's a breakdown of all the currently shipping iPhones from Apple.
Apple Continues Work on Liquidmetal Alloys for Use in Future Products
Apple has been rumored to be experimenting with amorphous metal alloys, aka Liquidmetal, ever since the company signed an exclusive deal with California-based company Liquidmetal Technologies back in 2010. Liquidmetal alloys demonstrate a different molecular structure than traditional metals, which results in a stronger, harder substance that is also durable, thin, and moldable into unique shapes.
The patents are highly technical and describe methods of creating parts layer by layer using bulk metallic glasses, aka Liquidmetal alloys, as is done with 3D printing, which Apple suggests is quicker and less expensive than traditional machining of parts. According to the patent, 3D printing could be especially useful for visualization, demonstration, and mechanical prototyping, as well as the production of patterns for molds.
Apple's patents indicate that Liquidmetal alloys could be used within iPhones, iPads, iPods, and as part of a digital display or computer monitor. Apple also specifies potential uses in the Apple TV, remote controls, hard drive tower housings, laptop houses, keyboards, track pads, mouses, speakers, and a "device such as a watch or a clock."
Rumors have long suggested that Apple could use Liquidmetal in its device casings, allowing the company to create slimmer products that are highly resistant to wear. The former director of research at Liquidmetal Technologies claimed that Apple would eventually "make the iPhone out of it."
Following its deal with Liquidmetal Technologies, Apple began testing the manufacturing capabilities of the alloys by crafting the iPhone 3G's SIM eject tool from a Liquidmetal alloy. Though minor components have been constructed from Liquidmetal alloys, one of the original inventors of Liquidmetal suggested in 2012 that the use of the alloys in major components was still two to four years off.
Apple has, however, recently been awarded a patent on the mass production of amorphous metals, indicating that the company is continuing to make progress with the material.
