Despite seemingly dropping plans for a sapphire display for the iPhone, Apple continues to be haunted by its brief venture into manufacturing using the material.
In addition to Apple’s sapphire supplier GT Advanced Technologies going bankrupt several years back, this week Apple was handed a lawsuit by manufacturer Hebei Hengbo Fine Ceramic Material. The company claims to have fallen out with Apple over terms for a contract involving high purity alumina melt stock, a material used as part of the sapphire process.
