High-Performance Alloys

Among stainless steels and alloys, these high-performance alloys provide superior functionality. Features include high corrosion resistance, heat resistance, high strength and other special features such as not being magnetizable. These alloys are used in harsh environments under tough conditions in advanced technology fields such as desalination, atomic power, semiconductors, solar cells and fuel cells.

Metals undergo dramatic expansion and contraction when the ambient temperature changes. The FeNi36 alloy NAS36 has a remarkably low coefficient of thermal expansion, one-tenth that of iron and one-twentieth that of aluminum. Controlled expansion alloys are used in applications requiring high definition and high precision such as semiconductor manufacturing equipment, inspection devices, flat panel display manufacturing equipment, precision molding dies for carbon fiber parts and astronomical telescopes. They are also used in bimetals made of low thermal expansion and high thermal expansion metals to convert temperature change into mechanical displacement.
