What is the weakness of tungsten?
Tungsten's hardness also has its downsides. In fact, the harder the metal, the more brittle and breakable it is (unlike gold, which is soft and malleable, meaning it will bend rather than break). If you drop a tungsten ring, or if you accidentally smash it against a hard surface, the metal may crack or shatter.
