Phosphor bronzes are alloys consisting of tin, phosphorus and copper as main constituents, sometimes with additions of zinc and lead. The structure is made up of three phases:
* A matrix of copper with tin in solid solution, known as the alpha phase, which is comparatively soft
* A tin rich delta ...

Electrochemical lithium insertion have been studied in the alkaline phosphate tungsten bronze K2P4W12O44 through galvanostatic and potentiostatic techniques. The maximum amount of lithium inserted, near to 14 lithium ions per formula, leads to a specific capacity of 120 Ah/kg when the cell was discharged until 1.0 V vs Li+/Lio. Nevertheless, ...

Brasses are alloys of copper and zinc (generally 5 to 40%), and may contain small amounts of other alloying elements. Most are available in a range of forms and can be fabricated by casting, forging, stamping, rolling, extrusion and machining.
They fall into two classes, the alpha alloys with less than ...
