What is Melonite
An ad for a Springfield Arms pistol says the barrel is Melonite.
A Google search says Melonite is a "telluride of nickle". Whatever that means. Other references say it is a finish or coating for metals.
The SA ad would then be confusing. Is the whole barrel just plated with this stuff or is it all made from Melonite?
What, in layman's terms, is Melonite?
