Recently, Apple Insider, found a patent that surfaced from Apple that points to a possible future of stainless steel.
The patent says points to the idea that there would be a portfolio made of stainless steel devices, but that the devices would be coated with nitride to make them scratch proof. The document says that the layer would be 15 microns thick.
The patent was filed in April by Douglas Weber. It says that steel is cheaper than aluminum to make, and that it is easier to machine.
The future of Apple may look stainless.
