Copper alloys have been
designed to match capabilities to needs and are amongst
the oldest materials in the service of man.
Even small additions of a second
element can significantly effect a property.
The alloying elements employed
to alter the characteristics of pure copper used for
copper alloy engineering tubing impart differing characteristics,
often in combination: strength, temperature capabilities,
machining properties or corrosion resistance. They
all retain to some degree basic properties of copper:
ductility, thermal and electrical conductivity.
All the alloys are fairly
strong: high strength alloys can be treated to achieve
well over 500 MPa (aluminium brass reaches 550 and
phosphor bronze over 650 MPa).
