Why Copper
Beryllium?
Designers of electronic
connectors and components are being challenged with increasingly shortened
product development cycles and the need for lower cost component solutions
while addressing the technology-driven requirements of miniaturization,
higher pin counts, faster operating speeds, higher operating temperatures
and greater durability. Copper beryllium strip
and rod
alloys provide a cost-effective, reliable solution for this challenge
because of their unique combination of properties. Copper beryllium
allows a designer to minimize the amount of material used a given design,
thereby reducing overall component cost without sacrificing performance.
User Benefit
/ Solution
Copper beryllium is specified and used in applications where
a combination of high strength, high conductivity, excellent stress
relaxation resistance and good formability are necessary to optimize
a contact design and maximize the reliability of the interface. Beryllium
copper offers the following advantages over other copper alloys:
- Higher elastic
modulus, which allows for a wider contact deflection range
- Higher yield
strength, which maximizes allowable beam deflections within the elastic
range, allows for reduced beam lengths, and subsequently, miniaturization
- Superior stress
relaxation resistance at elevated temperatures for the maintenance
of stable contact force over time
- Higher conductivity,
which minimizes bulk resistance and connector temperature rise
- Greater ductility,
which allows for better forming characteristics
