OverviewAge-hardened alloyPropertiesToxicityUsesSpecialized variantsExternal links
Beryllium copper (C17200 & C17300) is an age-hardening alloy that attains the highest strength of any copper base alloy. It may be age hardened after forming into springs, intricate forms, or complex shapes. It is valued for its elasticity, corrosion resistance, stability, conductivity, and low creep. Tempered beryllium copper is C17200 and C17300, which have been age-hardened and cold-dr

6 FAQs about [Beryllium copper elastic energy storage density]
Is copper beryllium a high strength alloy?
Copper beryllium high strength alloys are less dense than conventional specialty coppers, often providing more pieces per pound of input material. Copper beryllium also has an elastic modulus 10 to 20 percent higher than other specialty copper alloys.
What are the physical and mechanical properties of copper beryllium?
Copper beryllium’s physical and mechanical properties differ considerably from those of other copper alloys because of the nature and action of the alloying ele-ments, principally beryllium. Varying the beryllium content from about 0.15 to 2.0 weight percent pro-duces a variety of alloys with differing physical properties.
What is the density of beryllium copper?
In words, the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance. The standard SI unit is kilograms per cubic meter (kg/m3). The Standard English unit is pounds mass per cubic foot (lbm/ft3). Density of Beryllium Copper is 8250 kg/m3.
What is the conductivity of copper beryllium?
The B14 (Copper-Nickel-Beryllium) exhibits a good conductivity which exceeds 45 % IACS (at 20°C = 3.6 μΩcm). For special tempers it can reach up to 60 % IACS (at 20°C = 2.9 μΩcm). The B8 achieves 65 %IACS. Generally speaking the corrosion resistance of copper beryllium is similar to that of other copper based alloys with high copper content.
What is welded copper beryllium?
Welding copper beryllium offers advantages over other structural alloys particularly those depending on cold work for strength. In copper beryllium, a welded joint can retain 90 percent or more of the base metal mechanical properties.
What is the thermal expansion coefficient of beryllium copper?
The thermal expansion coefficient of beryllium copper is independent of alloy content over the temperature range in which these alloys are used. The thermal expansion of beryllium copper closely matches that of steels including the stainless grades. This insures that beryllium copper and steel are compatible in the same assembly.
