With such a huge growth in touch screen use globally, there was a kind of inevitability that the only thing that could potentially hinder this continued growth was one of resource limitations. But what will replace ITOs?

Super alloys are built to function well in high temperature applications. Some of the components that use super alloys include gas turbine engines, rocket motors, nuclear reactors, submarines, and petroleum equipment.
Titanium alloys are developed by adding varying quantities of alloying metals to the base metal titanium. Each alloying metal helps to enhance the properties of corrosion resistance, ductility, durability, tensile strength etc.
Super alloys provide high performance at high temperatures, excellent resistance to creep, good surface stability, and good corrosion and oxidation resistance. They are highly sought by the aircraft, automobile, medical, and defense sectors.
