Materials: Non-Ferrous Metals
Copper provides a diverse
range of properties: good thermal and electrical
conductivity, corrosion resistance, ease
of forming, ease of joining, and color.
However, copper and its alloys have relatively
low strength-to-weight ratios and low strengths
at elevated temperatures. Some copper alloys
are also susceptible to stress-corrosion
cracking unless they are stress relieved.
Next to silver, copper is the next best
electrical conductor. It is a yellowish
red metal that polishes to a bright metallic
luster. It is tough, ductile and malleable.
Copper has a disagreeable taste and a peculiar
smell. Copper is resistant
to corrosion in most atmospheres including
marine and industrial environments. It is
corroded by oxidizing acids, halogens, sulphides
and ammonia based solutions.
Copper and its alloys --
the brasses and bronzes -- are available
in rod, plate, strip, sheet, tube shapes,
forgings, wire, and castings.
