I thought TG was a very brittle metal
TRS is a measure of the strength of Tungsten Carbide. Tensile strength is not used on tungsten carbide because it is too brittle
They are very resilliant. They don't scratch or dent. They're the toughest metal available for jewelry, won't tarnish or anything. One down side though, you can't mount any form of stone
Beats having an arsehole anyday. But do remember, it won't strecth when required.
