Bronze, the world’s first copper alloy, was born. Copper alloys have come a long way since and are now a key material in many applications, from LCD televisions and smartphone touchscreens ...

ON account of their great industrial importance, the alloys of copper and zinc have at various times been studied by many observers. Mallet, Matthiessen, Riche, Thurston, and a host of others have ...

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 ...

Copper and zinc atoms are different sizes. This distorts the regular lattice structure in brass, so layers of atoms cannot slide over each other so easily. This makes brass stronger than copper or ...

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 ...
