Why Do We Need To Make Alloys?

To strengthen the metals we use and draw out other desirable qualities therein.

Because all metals except titanium are weak in their pure form. In a pure metal all the atoms are the same size so under stress when the metal bends the atoms can slide over each other. So the metal can easyly bend... And eventually break. And most pure metals are fr***** big $$$. Even slag has been used in iron

To improve the quality of metals,making them hard and some of them not to corrode.to make quality products with them so they can last long
