Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze, and
spring copper, is a copper alloy with 0.5–3% beryllium.Copper beryllium alloys are
often used because of their high strength and good conductivity of both heat and
electricity. It is used for its ductility, weldability in metalworking, and machining
properties.
It has many specialized applications in tools for hazardous environments,
musical instruments, precision measurement devices, bullets, and some uses in the field
of aerospace. Beryllium copper and other beryllium alloys are harmful carcinogens that
present a toxic inhalation hazard during manufacturing.
Nuclear weaponry
Lightweight alloys in fighter jets, helicopters, and satellites
Missile gyroscopes and gimbals
Sensors in satellites and optical systems
Mirrors in infra-red and surveillance equipment
Skin panels for rocket boosters (e.g. Agena)
Inner stage joining elements in missile systems (e.g. Minuteman)
Rocket nozzles
Explosive ordnance disposal equipment
Pacemakers
CAT scanners
MRI machines
Laser scalpels
Springs and membranes for surgical instruments (beryllium iron and beryllium nickel
alloys)
Perhaps the most common uses for Beryllium copper are in electronic connectors, telecommunications products, computer components, and small springs. Beryllium Copper is exceptionally versatile and known for: High electrical and thermal conductivity and high ductility.
