Aluminum Alloys
Aluminum Alloys
Aluminum alloys are metal materials widely used in many industries due to their lightness, durability, and workability. Pure aluminum may not be strong enough, so it is alloyed with various elements to enhance performance characteristics. Understanding the general types and applications of aluminum alloys can help you better understand how these alloys are used in various sectors.
What Are Aluminum Alloys?
Aluminum alloys are metal mixtures created by adding other elements to pure aluminum. These alloys improve the properties of aluminum and make it suitable for specific applications.
Types of Aluminum Alloys
Aluminum alloys are generally divided into two main categories: Aluminum-Silicon Alloys (Al-Si) and Aluminum-Copper Alloys (Al-Cu). Both categories include different types of alloys and are used in various applications.
