Adjustable Wrench with 'BeCu' on the side, to show that it is made from beryllium copper. 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 ...

Beryllium oxide (BeO), also known as beryllia, is an inorganic compound with the formula BeO. This colourless solid is an electrical insulator with a higher thermal conductivity than any other non-metal except diamond, and exceeds that of most metals. [12]
Beryllium oxide is useful for many applications that require the combined properties of an electrical insulator and an excellent heat conductor, with high strength and hardness and a very high melting point. Beryllium oxide is frequently used as an insulator base plate in high-power transistors in radio frequency transmitters for
Traces of bismuth and beryllium disrupt the surface aluminium oxide. Strontium refines grain structure of the brazing alloy, improving ductility and toughness. 20: 2: 73: 5: Bi,Be,Sr Al 61.3 Cu 22.5 Zn 9.5 Si 4.5 Ni 1.2 Bi 0.01 Be 0.01 Sr 0.01: Al–Cu–Si 495/505 [5] – For brazing aluminium. Traces of bismuth and beryllium disrupt the ...
[14] [15] [16] Black iron(II,III) oxide (Fe 3 O 4, magnetite) also works. [17] Other oxides are occasionally used, such as MnO 2 in manganese thermite, Cr 2 O 3 in chromium thermite, SiO 2 (quartz) in silicon thermite, or copper(II) oxide in copper thermite, but only for specialized purposes. [17] All of these examples use aluminum as the ...
Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. [1] It is used to add mild corrosion resistance, for appearance, and to minimize light reflection. [ 2 ]
The ignition is easier and the arc burns more stably than without the addition of thorium. For powder metallurgy applications, binders have to be used for the sintering process. For the production of the tungsten heavy alloy, binder mixtures of nickel and iron or nickel and copper are widely used. The tungsten content of the alloy is normally ...
