What is Beryllium Copper?
Beryllium copper (BeCu), also known as copper beryllium (CuBe),
beryllium bronze and spring copper, is a copper alloy with 0.5—3%
beryllium and sometimes other elements. It has superb metalworking,
framing and machining properties. It has many specialized
applications in electrical industry, industrail and aviation.
The small proportion of beryllium to copper makes a group of high
copper amalgams with quality as high as compound steel. The first
of the two families, C17200 and C17300, incorporates high quality
with moderate conductivity, while the subsequent family, C17500 and
C17510, offers high conductivity with moderate quality.
Where is Beryllium Copper used?
Beryllium copper is a non-ferrous composite utilized in springs,
spring wire, load cells, and different parts that must hold their
shape under rehashed anxiety. It has high electrical conductivity
and is utilized in low-flow contacts for batteries and electrical
connectors.
Other Uses:
Ultra-low temperature cryogenic equipment, such as dilution
refrigerators, because of its mechanical strength and relatively
high thermal conductivity in this temperature range
Servicing magnetic resonance imaging (MRI) machines, where high
strength magnetic fields make use of ferrous tools dangerous, and
where magnetic materials in the field can disturb the image.
It has important applications in oilfield tools, aerospace landing
gears, robotic welding, and mold making applications.
