I came accross some leashes with bronze snaps. Not being a student of metalography, I was wondering which is the better metal for snaps. I know that brass is from copper and zinc, and that bronze is from copper and tin. I know that adding tin to metals makes them stronger/harder, but I don't know what zinc does to metals. My biggest concern is the strength and durability of the snap. So, which is better?
I do know that zinc helps with making metals less suceptable to corrosion (rusting). Think of zinc covered nails and the fact that zinc is added to drinking water to keep the pipes from rusting. The only thing I know that is bad about brass is that it usually contains lead, but in the case of a leash I don't think this really matters.

Kevin,
Bronze snaps are great, and very common on quality dog leashes.
I've never seen a Brass snap on a dog leash, but brass tends to be weak and maleable in comparison to bronze.
Zinc (Die-Cast) is hard, but brittle and can be broken by a dog. I see zinc snaps on nylon leashes, but don't recommend them for large dogs.
Stainless Steel is another equally good option to bronze, but can be more expensive. SS is actually much stronger than any of the above as well.

Herm Sprenger makes collars of Stainless Steel, Chrome Plated Steel, Brass & Currogan (Copper-Tin Alloy). We have one Brass Fur Saver an it has become bent and deformed much easier than any of the other materials. The Currogan is hard & tough and has a tarnished copper color to it. As a side note, if you have a light colored dog, the Brass or Currogan collars can turn the hair on the dogs neck green too.
