Non tarnish brass alloy?

2004

Hi,

We are manufacturers of artificial jewelry. For a long time now we have been looking for a chemical coating that would give our gold n silver plated jewelry a long life.but we have been unsuccessful. Is there a chemical coating that would keep our products from getting tarnished? do you know where we can buy NON TARNISHABLE BRASS ALLOY OR METAL?

Kindly help us.

Mr Keyur Barad,

There are a number of very good Anti tarnish treatments locally available.

1) Silver Anti tarnish
2) Gold anti tarnish
3) Clear Electrophoretic lacquer

You can use aluminum bronze(copper+5-8%Al). It is very resistant to corrosion.
