john_childs said:*A magnet will not stick to aluminum alloy. If a magnet sticks to the
rim then the rim is steel alloy. If the magnet doesn't stick then
it's aluminum alloy. Just try the magnet away from the spokes. If
the magnet is too close to the spokes then it could be attracted to
the spoke instead of the rim and skew the results.
Steel is also an alloy so calling it an alloy rim is vague. It's
either steel alloy or aluminum alloy. I mention this just to keep
Harper happy so he doesn't try to remind me that steel is an alloy
too. *
Thanks. I find this alloy ambiguity tiresome. Some stainless steel
alloys are non-magnetic. Some are highly magnetic. Nickel is highly
magnetic but unlikely to be used in pure form on a rim. However, the
most common strike plate for a finish overplate is nickel.
If a magnet sticks to a rim the most likely conclusion is that it is a
common steel alloy.
Aluminum in its pure form is, of course, not an alloy. It is commonly
alloyed to make it harder, more machinable, more easily welded, or to
give it a myriad of other properties. Steel is always an alloy by
definition. Saying it is a steel rim, not an alloy rim, makes no sense
whatsoever.
