Chinese scientists have come up with a groundbreaking alloy with fatigue resistance up to 10,000 times greater than steel.

Most of these alloys were combinations like copper-silver or silver-gold and used with so-called hard soldering ... and SnCu (tin-copper). SnAgCu alloy with 3% silver and 0.5% copper (SAC305 ...

Many pure metals are too soft for many uses. They can be made harder by adding another element to the pure metal, so forming an alloy. This explains why an alloy often has more uses than the pure ...
