Customers’ design welcome;
Because of its high conductivity and relatively low price compared
with copper in the 1960s, aluminium was introduced at that time for
household electrical wiring in North America, even though many
fixtures had not been designed to accept aluminium wire. But the
new use brought some problems:
The greater coefficient of thermal expansion of aluminium causes
the wire to expand and contract relative to the dissimilar metal
screw connection, eventually loosening the connection.
Pure aluminium has a tendency to creep under steady sustained
pressure (to a greater degree as the temperature rises), again
loosening the connection.
Galvanic corrosion from the dissimilar metals increases the
electrical resistance of the connection.
All of this resulted in overheated and loose connections, and this
in turn resulted in some fires. Builders then became wary of using
the wire, and many jurisdictions outlawed its use in very small
sizes, in new construction. Yet newer fixtures eventually were
introduced with connections designed to avoid loosening and
overheating. At first they were marked "Al/Cu", but they now bear a
Another way to forestall the heating problem is to crimp the
aluminium wire to a short "pigtail" of copper wire. A properly done
high-pressure crimp by the proper tool is tight enough to reduce
any thermal expansion of the aluminium. Today, new alloys, designs,
and methods are used for aluminium wiring in combination with
Wrought and cast aluminium alloys use different identification
systems. Wrought aluminium is identified with a four digit number
which identifies the alloying elements.
Cast aluminium alloys use a four to five digit number with a
decimal point. The digit in the hundreds place indicates the
alloying elements, while the digit after the decimal point
indicates the form (cast shape or ingot).
