Characteristics of Berylco Alloys

High Strength, Good Conductivity Alloys
Berylco 25 alloy UNS C17200, can attain mechanical properties up to 200ksi and a hardness of RC 44
Berylco 33/25, UNS C17300 is a free machining version with the same characteristics as Berylco 25

High Conductivity, Good Strength Alloys
Berylco 10 and 14 alloys UNS C17500 and C17510 can obtain conductivity over 45% IACS and strengths up to 140ksi UTS. This combination of properties makes these alloys ideally suited for heat dissipating modules, resistance welding components and other electrical applications.

High Strength and Elastic Modulus
Beryllium Copper Alloys can attain high strengths through precipitation hardening. The strength of these alloys allow for the design of smaller, lighter components that can endure high bending stresses when used as a spring material. Typical applications include: springs, electrical switches, diaphragms, bellows, clips washers and connectors.

High Fatigue Strength
Beryllium Copper exhibits excellent resistance to fatigue strength under reverse bending (up to 45 ksi) which qualifies its use in applications where other alloys fail to provide the same level of reliability. Applications are varied & include: springs, electrical switches contacts, relays, connectors & washers.

Elevated Temperature Properties and Resistance to Stress Relaxation

Beryllium Copper is a precipitating hardening alloy with excellent properties at elevated temperatures and can be used in a wide range of temperatures with little loss of mechanical properties

Good Formability
Beryllium Copper alloys can be formed into complicated shapes in an annealed or cold worked temper. The highest mechanical properties, commonly known as peak properties, can be obtained with proper heat treatment after forming.

High Electrical Conductivity
The electrical conductivity of beryllium copper ranges from 16 to 65% IACS. Beryllium copper is the material of choice for high current density springs requiring low heat generation, due to the alloy’s combination of high electrical conductivity, thermal conductivity and strength.

Corrosion Resistance
Beryllium copper has good corrosion resistance nearly equal to nickel silver. Not susceptible to hydrogen embitterment. Applications can be found in marine and chemical industries

Reliability
There is no need to trade off one property to satisfy another. Beryllium copper allows engineers to employ a unique design approach when other materials will not perform. This is an important aspect for designers looking to miniaturise, yet not compromise, their component integrity.

Spring Properties and Miniaturisation

Beryllium copper alloys have high mechanical strength and favourable elastic modulas which makes them highly suitable as a spring material

Machinability
Beryllium copper can be machined into intricate shapes. Its machinability in the age hardened condition is comparable to many other copper base alloys and better than stainless steels. Its dimensional stability is far superior to any other copper base alloy.

Abrasive Resistance
Beryllium copper offers attractive wear resistant properties compared to other copper base alloys and many ferrous alloys because of its complex oxide transfer wear films. Typical applications are shell moulding, plastic moulds, injection moulding nozzles and cores, bearings and valves.

Non- Magnetic
Extremely useful for housing sensitive detectors affected by magnetic fields.

Non- Sparking
Beryllium copper is non-sparking and NGK Berylco produces safety tools for use in environments where flammable solvents, fuels, material, gases and residues are present, causing potential risk of sparks resulting in a fire or an explosion. While many non-ferrous alloys meet non sparking standards, only beryllium copper has the superior strength and hardness not found in safety tools made from aluminium, bronze, and brass. Berylco safety tools provide maximum torque and shear strength plus exceptional wear resistance. Typical uses are in mining, gas and petrochemical industries.
