Zinc alloy
A zinc alloy is a compound or mixture of zinc with other metals .
The most important zinc alloys are those with copper ( brass , tombac ), to which tin ( bronze etc.) is often added, also copper and nickel ( nickel silver ).
Zinc is also a component of numerous other alloys . An alloy of aluminum , copper and zinc is used to solder the aluminum, an alloy of antimony , copper, zinc as an anti-friction metal, alloys of zinc, lead , copper and antimony for calico printing rollers and zinc antimony alloys for grape balls and traction sheaves.
Titanium zinc is used as a building material , an alloy with copper , with which zinc is actually incompatible. The installation of copper and zinc as a component directly next to each other leads to the destruction of the zinc. The same applies if copper is arranged above zinc and rainwater flows from the copper to the zinc. The cause of this is bimetal corrosion .
Alloys of tin, zinc and lead are similar to the Britannia metal, but of higher quality than it. Molten zinc dissolves iron, and galvanizing the iron creates a bond that is difficult to melt ( hard zinc ).
