Name of 15 alloys which v use in r daily life????

Most metals are not used in pure form - even things thought of as single elements, like aluminum or titanium bars, are actually alloyed with a bit of other elements to improve their properties. Alloys with large amounts of several elements also exist: br, stainless steel, and 14k gold are all examples. You can probably come up with more on your own easily...I suppose with a prompt like that, you could just name 15 grades of steel.
