Thus an alloy of zinc 50, copper 49, was in hardness as compared with cast iron -604; while an alloy of copper 66, zinc 33, was only 472 in hardness. The fact was also eliminated that when the ...

This precaution is not necessary, unless the alloy contains a metal requiring a high temperature for its fusion, as, for instance, copper or iron. In alloys oontaining tin, however, a laler of ...

There are several alloys of various metals, such as alloys of Aluminium, Potassium, Iron, Cobalt, Nickel, Copper, Gallium, Silver, Tin, Gold, Mercury, Lead, Bismuth, Zirconium, and rare earth. Based ...

It can be alloyed with carbon in various amounts to make steel. Alloys typically added in addition to carbon include manganese, chromium, molybdenum, vanadium, tungsten, cobalt, silicon, and nickel.

metals do not contain iron and are not magnetic ... that is gold coloured and darkens when oxidised with age An alloy of copper and zinc, can be cast and machined, used for musical instruments ...

UNUSUAL physical properties exhibited by alloys of the iron–nickel system in various ranges of composition have led to extensive investigations 1 of this system in the past. One group of alloys ...
