The major problem with Pot Metal (Zinc Die Casting)
is that it corrodes - badly! Its use is widespread in
the automotive and motorcycle industry, mainly because
it is easy to cast into intricate parts. Unfortunately,
the metal is easily subjected to corrosion, particularly
by mild acid attack. The zinc readily degenerates in
the presence of even a mild acid such as tomato ketchup.
Pot Metal will polish up and look very good, for about
2-3 days, then it rapidly dulls down to a leaden look.
This can be most unattractive on vehicles with lots
of shiny aluminum or chrome. By polishing the part,
then immediately plating it with Pot Metal Electroless
Nickel, the metal can be given a long term, bright,
shiny surface, closely matching the other components
on the vehicle. |
