Below is a list of Beryllium Copper manufacturers from Irving, Texas. Beryllium copper is the strongest, most durable copper alloy that contains anywhere from 0.5 to 3% beryllium, an alkaline earth metal that is mainly used as a hardening agent in alloys. Pure copper by itself is soft and malleable, but with the addition of beryllium, exhibits good corrosion and oxidation resistance as well as high strength, without losing formability. It is very electrically conductive, but will not spark and is non magnetic.
