	Resources: Standards & Properties - Copper & Copper Alloy Microstructures: Copper Beryllium
		Copper beryllium alloys are used for their high strength and good electrical and thermal conductivities.
		The high strength of the copper beryllium alloys is attained by age hardening or precipitation hardening.
		The precipitation occurs during the slow cooling of the alloys because the solubility of beryllium in alpha copper decreases with decreasing temperature.

		They are comparable to steel in density, most copper alloys being only about 10% heavier, while those with a lot of aluminium or silicon may be slightly less dense than steel.
		The cost of copper-base alloys is generally higher than that of steels but lower than nickel-base alloys.
		Copper-based alloys have lower melting points than steels and are more readily produced from their constituent metals.

	Beryllium copper - Wikipedia, the free encyclopedia
		Beryllium copper alloys are resistant to non-oxidizing acids (hydrochloric acid, carbonic acid, etc.) and other plastic decomposition products.
		Beryllium copper is also frequently used in the manufacture of professional-quality percussion instruments, especially tambourine and triangle, where it is prized for its clear tone and strong resonance.
		The hardening process requires rapid cooling of the annealed metal, resulting in a solid state solution of beryllium in copper, which is then kept at 200-460 °C for at least a hour, facilitating precipitation of metastable beryllide crystals in the copper matrix, resulting in increase of the alloy strength.

	Innovations: Cu Hull Sheathing Nov03
		Copper and some of the copper alloys, in particular the copper-nickel alloys, have been demonstrated to be highly corrosion resistant in marine environments.
		It was some 20 years later that copper nails were used instead of iron nails as the latter caused galvanic corrosion of the iron, resulting in the loss of the copper plates.
		One alternative to copper or copper-nickel powder suspensions is the use of thin sheet fixed to the outside of the hull.

	Effects of Composition, Processing, and Structure on Properties of Copper and Copper Alloys
		Work hardening is the principal hardening mechanism applied to most copper alloys, the degree of which depends on the type and amount of alloying element and whether the alloying element remains in solid solution or forms a dispersoid or precipitate phase.
		Copper-nickel-zinc alloys, also called nickel-silvers, are a family of solid-solution-strengthening and work-hardening alloys with various nickel-zinc levels in the Cu-(4-26)Ni-(3-30)Zn ternary alloy system valued for their strength, formability, and corrosion and tarnish resistance, and, for some applications, metallic white color.
		High-copper alloys (C16000 to C19900) are designed to maintain high conductivity while using dispersions and precipitates to increase strength and softening resistance: iron dispersions in Cu-(1.0-2.5)Fe alloys (C19200, C19400), chromium precipitates in Cu-1Cr (C18200), and the coherent precipitates in the Cu-(0.3-2.0)Be-Co-Ni age-hardening alloys (C17200, C17410, and C17500).

	Beryllium Copper - 170, 172, 175, 17510
		Beryllium copper alloys achieve their properties through alloying elements, cold rolling, and a precipitation hardening heat treatment.
		Due to their submicron size, very fine distribution, and interaction with the copper matrix, these precipitates are responsible for the unique properties that distinguish beryllium copper from other copper alloys.
		Before rolling to final thickness, beryllium copper is given a "solution anneal" which puts the beryllium in solution within the copper matrix.
