Introduction of C17200 Berylliium Copper Alloy 25:
Beryllium copper UNS.C17200 is also known as various names like
spring copper, beryllium bronze, and copper beryllium.
Beryllium copper combines non-magnetic as well as non-sparking
properties.
It has unique machining and metalworking qualities.
Beryllium copper is applicable in numerous applications because of
its unique features
It is a flexible, weldable, and machinable alloy which resistant to
non-oxidizing acids, plastic decomposition products, abrasive wear
and galling.
It can handle high-temperature heat to improve its strength,
durability, and electrical conductivity.
These properties allow it to fit in the various criteria of
essential applications.

Excellent Properties of CuBe2 Copper Alloys:
Key Technology of Beryllium Copper(Heat treatment)
Age Hardening
Age hardening significantly enhances the material’s strength. This
reaction is generally carried out at temperatures between 260°C and
540°C depending on alloy and desired characteristics. This cycle
causes the dissolved beryllium to precipitate as a beryllium rich
(gamma) phase in the matrix and at the grain boundaries. It is the
formation of this precipitate which causes the large increase in
material strength. The level of mechanical properties attained is
determined by the temperature and time at temperature. It should be
recognized that beryllium copper has no room temperature aging
characteristics.
