The alloy is harder and stronger than the pure metal. Steel contains atoms of other elements as well as iron. These atoms have different sizes to iron atoms, so they distort the layers of atoms in ...

In a first, researchers have developed a new copper alloy that's one of the most resilient copper-based materials ever made.

S420—S420 structural steel plate is a low-alloy, high-strength European standard structural steel within the EN 10025:2004 standard. S690—S690 is a fine-grain, Q&T, high-strength structural steel.
