A bronze is an alloy of copper and other metals, most often tin, but also aluminium and silicon. Aluminium bronzes are alloys of copper and aluminium. The content of aluminium ranges mostly between 5% and 11%. Iron, nickel, manganese and silicon are sometimes added.

Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals (such as phosphorus) or metalloids (such as arsenic or silicon).

Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. [11] Manganese and its common ions are paramagnetic. [12] Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen. [13]
Silicon is also soluble and usually forms SiO 2 •M x O y. Manganese mostly dissolves in ferrite forming MnS, MnO•SiO 2, but also carbides: (Fe,Mn) 3 C. Chromium forms partitions between the ferrite and carbide phases in steel, forming (Fe,Cr 3)C, Cr 7 C 3, and Cr 23 C 6. The type of c#arbide that chromium forms depends on the amount of ...
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Ferrosilicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel (so called blocking the heat); ferromanganese, spiegeleisen, calcium silicides, and many other materials are used for the same purpose. [5]
