why do we use alloys instead of pure metals

An alloy is a mixture of two elements, one of which is a metal. Alloys often have properties that are different to the metals they contain. This makes them more useful than the pure metals alone. For example, alloys are often harder than the metal they contain. Alloys contain atoms of different sizes, which distorts the regular arrangements of atoms.

This makes it more difficult for the layers to slide over each other, so alloys are harder than the pure metal. A summary of three common alloys, the metals they contain, and their typical uses
Now try a Smart alloys have unusual properties. Nitinol is an alloy of nickel and titanium, and is known as a shape memory alloy. If nitinol is bent out of shape, it returns to its original shape when it is either heated or an electric current is passed through it.

This property makes it useful for making spectacle frames - they return to their original shape if they are put in hot water after bending them. Now try a What Are the Main Industries of Spain? Spain's largest industries by annual output are textiles and apparel, food and beverage, metals, chemicals and shipbuilding.

Tourism is also a significant. What Is Stick Welding? Stick welding is a welding process that uses electric current and an electrode to form an electric arc that joins different metals. The electric arc melts. What Advantages Do Alloys Have Over Pure Metals?

Compared to pure metals, alloys can be stronger, more resistant to damage and more versatile. The advantage of alloys differs depending on the specific all. Why Do We Make Alloys? Alloys are made because they contain properties that the pure metal doesn't have, which makes them more useful in practical applications. Alloys can have s.
