What is Gold-filled wire?

The name “gold-filled” is confusing because it is not wire filled with gold, it’s gold wire that is filled with a base metal. Basically, yellow gold is pressure bonded, with heat, to a base metal (usually a brass alloy that is 90% copper and 10% brass). 

Wait, isn’t that gold plating? Nope. Gold plating is different.

Here’s the thing...

Gold filled jewelry has 100x more gold alloy than gold plated jewelry. Because that layer is so much thicker it will  last longer, and stands up to wear and tear better than gold plated jewelry.

Gold filled is more valuable and tarnish resistant. It does not flake off, rub off (okay, I think it can rub off, but it would require a whole lotta wear n’ tear) or turn colors. Anyone who can wear gold can likely wear gold filled without worries of allergic reaction to the jewelry. Gold filled jewelry is an economical alternative to solid gold.

Solid gold is too malleable. I went over that before in my Gold Demystified post. Gold filled is the next level after gold and is a great alternative to gold.  

Here are a couple of visual aids to help you out:
