Quick note
Quote:
The prongs that look tin/silver in color are brass
Not always. Low end cables from the dollar store or walmart etc often use an aluminium tin alloy with a small bit of copper and a thin nickel core.
Always etch your metals first to check the underlying material. But if you can bend the blade by hand it’s not your standard brass. Brass plated steel connectors also exist. Especially from China and today, many low cost ones from Taiwan/Taipei.
The alloy ones are worth about 15c per pound clean. The steel ones are under a penny.
