Answer explanation

The property of metals that is described as having a high melting point is the correct choice.

What is the primary reason alloys are created instead of using pure metals?

• To decrease the cost

• To improve the appearance

• To enhance the metal's properties

• To increase the weight

Answer explanation

Alloys are created to enhance the metal's properties, such as strength, durability, and corrosion resistance, which are often superior to those of pure metals.
