Beryllium copper has physical and mechanical properties that are considerably different than other copper alloys. This is mainly because the action and nature of the alloying elements (beryllium). On average, the content of beryllium is between 0.15 and 2.0 weight percent, which allows us to create a wide variety of alloys that have different physical and machinable properties. For instance, a high conductivity allow will have 19 million psi. A high conductivity alloy on the other hand, requires 20 million psi to achieve high conductibility. We can help strengthen both thermal and electrical conditions.
Beryllium copper is compared to steel in certain cases. The ability for easy thermal expansion matches steel (including stainless grades). Beryllium copper and steel can be compatible in the same assembly.
The magnetic permeability of beryllium copper wire is almost at unity. This means that the alloy is transparent to slowing magnetic fields. This alloy is commonly used in the electronic field because of the physical properties of being non-magnetic.
Beryllium copper has high fatigue strength because it resists fatigue failure under several conditions, which includes toughness and high static strength. It also has the ability for diffusing strain through work hardening.
When comparing the physical properties of copper to beryllium copper, several differences will make themselves clear. For instance, beryllium copper wire has a higher strength while remain less dense than other specialty coppers. Beryllium copper will produce more pieces per pound of input material than compare to their counter parts. Lastly, Beryllium copper has a elastic modulus that is between ten to twenty percent high than other copper alloys.
