The characteristics of beryllium copper:

Beryllium copper is a copper alloy that combines strength, electrical conductivity, workability, fatigue resistance, heat resistance, and corrosion resistance. It is widely used in the field of electronic components such as connectors, switches, and relays. Beryllium copper is available in a variety of alloys such as strip, sheet, bar and wire.

strength:

Through aging hardening treatment, the tensile strength can reach 1500N/mm2, so it can be used as a high-strength elastic material that can withstand higher bending stress.

Processability:

The “aged material” before age hardening can be subjected to complex forming processing.
Conductivity:

According to different alloys and specifications, the conductivity can reach the %IACS (International Annealed Copper Standard) range of about 20 to 70%. Therefore, it can be used as a highly conductive elastic material.

Fatigue resistance:

Due to its excellent fatigue resistance (high cycle times), it is widely used in parts that require long life and high reliability.

Heat resistance:

Because the stress relaxation rate is still small in high temperature environment, it can be used in a wide temperature range.

Corrosion resistance:

Compared with copper alloys such as white copper, beryllium copper has better corrosion resistance. It is a copper alloy material that is almost not affected by the environment and undergoes corrosion changes.

Main uses (different uses for different beryllium copper grades):

High-precision electronics, plastic and optical molds are used for soil heat dissipation, mold cores, punches, hot runner cooling systems, communication preparation equipment, electronic and electrical equipment, instrumentation, aerospace, automobile manufacturing, etc. material;

Manufacture of springs for various important purposes, elastic elements of precision instruments, sensitive elements and elastic elements that bear high load of changing directions;

Various types of micro-motor brushes, relays, mobile phone batteries, springs, connectors, and temperature controllers that require high strength, high elasticity, high hardness and high wear resistance.

RF coaxial connectors, circular connectors, printed circuit board test and spring contact test probes, etc.
