It's the standard for tooling and applications that demand from customers surface area durability. It is achievable to personalize a cloth’s Houses by modifying its hardness because hardness and ductility are inversely connected.
And that highlights one more reason low-reactivity metals are so practical. They normally happen In a natural way in varieties easy to work with. As an example, silver can be mined as pure silver.
