This microscopic "waviness" makes it incredibly difficult for defects (dislocations) to move through the metal. In simple terms, the internal structure of the metal is like a maze that traps wear and tear. The result? A material that is twice as hard as standard bronze but retains the slick, low-friction nature of copper. | Element | Weight % | |---------|-----------| |
