Iron soft enamel is almost the same looking as copper or bronze soft enamel
because the production procedures are quite similar, but the unit price is even much cheaper as iron is less expensive and it requires less time for polishing and electroplating. Some customers choose iron soft enamel
instead of copper soft enamel because brass and copper increased significantly from Feb. 2006.
If you want to tell the difference between copper soft enamel and iron soft enamel, here are some tips for your reference:
A: Use a magnet, if the pins stuck on magnet, it is iron soft enamel; if not, it is copper or brass soft enamel. This is the easiest way to tell the difference.
B: Check the metal area on pins, if it is a rough surface, that is iron material; if it is shiny, that is copper. Because we don't polish iron soft enamel actively unless customer request for it and are willing to pay more cents too. If iron pins have been polished, it is really difficult to tell the difference between each other.
C: Check the finishing. Usually, we use bronze (fake gold) plating to replace gold or use nickel to replace silver for reducing the unit price, if you found the plating is not so yellow as gold, it must be iron soft enamel.
