Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze, and spring copper, is a copper alloy with 0.5–3% beryllium. [1] Copper beryllium alloys are often used because of their high strength and good conductivity of both heat and electricity. [ 2 ]
Example of a copper alloy object: a Neo-Sumerian foundation figure of Gudea, circa 2100 BC, made in the lost-wax cast method, overall: 17.5 x 4.5 x 7.3 cm, probably from modern-day Iraq, now in the Cleveland Museum of Art (Cleveland, Ohio, USA) Copper alloys are metal alloys that have copper as their principal component.
Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira

Mixing about 2.0% beryllium into copper forms an alloy called beryllium copper that is six times stronger than copper alone. [106] Beryllium alloys are used in many applications because of their combination of elasticity, high electrical conductivity and thermal conductivity, high strength and hardness, nonmagnetic properties, as well as good ...
Low-temperature, fairly free flowing. Narrow melting range. For ferrous and non-ferrous metals. For copper alloys, brass, nickel silver, bronze, mild steel, stainless steel, nickel, and Monel. Cadmium-free substitute of BAg-2a. Moderate liquation, but can be exploited for bridging larger gaps. Pale yellow color. 30: 30: 40: Ag 45 Cu 30 Zn 25 ...
