Expensive bows have silver or gold fittings. Lesser bows usually have nickel-silver. Chinese bows have whatever metal was found that day at the scrapyard.

Any bow with silvery fittings can most likely tarnish, but it's easily fixed with polishing compound and a soft cloth.

I know this because when I wanted a little more (relative) tip weight Bernd Müsing of ARCUS sent me a replacement titanium screw.

In some folks, nickel can cause incapacitating skin reactions. Varnish can help.

When a bow maker has made a really good stick, he/she my use precious metals to hike up the price!

However, what ever is used to lubricate the screw as well as dirt from the hands, works it way under the frog and can things.

The decorative button itself is typically made from nickel, sterling silver, or gold. Though for really cheap and inexpensive bows, who knows? Nickel silver is typically made using 60% copper, 20% nickel and 20% zinc. Depending on the environment and ones chemical composition, the copper tone may start to come out and appear like rust over time. It will polish out.
