Somewhat true - but - why risk it when Ballistol works just fine?Proper cleaning with Hoppe's #9 will not hurt your nickel plating.
Don't soak the gun in it
Nickel is very similar to copper chemically so any cleaner or lube that attacks copper will likely attack nickel !
Nickel is a ferrous metal.
Someone was asleep in high school chemistry class. In order for a metal to be "ferrous", it must contain iron. Ferrous metals are magnetic with the exception of some stainless steels. Elemental Nickle is mildly magnetic. That is a fact despite what one's occupation is.Nickel is a ferrous metal. Copper isn't.
No, mostly copper. Pure Nickel (elemental), is slightly magnetic. But in the instance of a nickel coin, likely too much copper content to demonstrate any magnetism.OK. Dumb question. Aren't nickels made of nickel? A magnet won't stick to a nickel.
