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 and sometimes other elements. Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining properties. It has many specialized applications in tools for hazardous environments, musical instruments, precision measurement devices, bullets, and aerospace. Beryllium alloys present a toxic in

Beryllium and Beryllium Alloys Stonehouse - Major

Beryllium, Be, is the only light metal having a high melting point. The majority of the beryllium commercially produced is used in alloys, principally copper–beryllium alloys. The usage of unalloyed beryllium is based on its nuclear and thermal properties, and its uniquely high specific stiffness, ie, elastic modulus/density values.

Hydrogen embrittlement

Hydrogen embrittlement (HE) also known as hydrogen assisted cracking or hydrogen-induced cracking, describes the embrittlement of a metal by diffusible hydrogen. The essential facts about the nature of the hydrogen embrittlement of steels have now been known for 140 years. It is diffusible atomic hydrogen that is harmful to the toughness of iron and steel.

Beryllium contamination? Practical Machinist

Beryllium coordination chemistry and its implications on

Beryllium metal dissolves in the presence of ammono acids like ammonium halides and pseudo halides ([NH 4]X) in liquid NH 3 (vide supra). 66 Also beryllium halides acidify NH 3 to an extent that metallic beryllium dissolves. 76 This is presumably due to the strong Lewis acidity of the Be 2+ ion, which makes [Be(NH 3) 4] 2+ a potent Brønsted acid.
