Applications：

The addition of small amounts of yttrium to certain metals (such as chromium, molybdenum, titanium, and zirconium) or alloys (such as aluminum-magnesium alloy) can improve their performance or increase strength.

Yttrium is used in alloys as a refining agent and a grain refiner in the steel industry.
