what contains metal elements
There are a lot of metals. Why don't you list some and we'll order them? Alloy isn't a metal. It means different types of metals mixed. Steel is an alloy made of iron and carbon. So so far, you've listed two types of metal.... Steel is much stronger than aluminum.
The strongest metal is said to be the most reactive metal. The weakest metal is said to be the least reactive. The Reactivity Series is a list of metallic elements, with the strongest metals at the top and the weakest at the bottom. titanium is the strongest and mercury is the weakest. This question could be answered from the standpoint of metal alloys and their tensile strengths. But that is an engineering (applied science) answer. This is a chemistry forum, so I am answering from the chemistry perspective.
