Characteristics of Berylco Alloys
High Strength, Moderate Conductivity System
- BERYLCO 25 alloy, UNS C17200, can attain mechanical properties up to 200 ksi UTS and hardness of Rockwell C45.
- BERYLCO 33-25, UNS C17300, is the free machining version with the same characteristics as BERYLCO 25.
- At a moderate conductivity of 22%, these alloys offer the best wear resistance, fatigue strength, and hardness available in the copper alloy system.
High Conductivity, Moderate Strength
- BERYLCO 10 and 14, UNS C17500 and C17510, can attain conductivity over 45% IACS and strengths up to 140 ksi UTS.
- These alloys are ideally suited for heat dissipating modules, resistance welding components, and other electrical applications.
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 Wear 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.
- The high strength of age hardened parts makes them capable of sustaining bearing loads far in excess of other copper base alloys and gives the added advantage of compatibility with high hardness ferrous alloy shafts.
Corrosion Resistance
- Nearly equal to nickel silver and is not susceptible to hydrogen embrittlement.
High Fatigue Strength
- Beryllium copper is known to have high fatigue strength because of its toughness and resistance to local deformation.
Non-Magnetic
- Extremely useful for housing sensitive detectors affected by magnetic fields.
