Aluminum alloys are becoming increasingly popular across various industries due to their versatility, strength, and lightweight characteristics. Understanding the different types of aluminum alloys and their properties can help you choose the best material for specific applications.
Aluminum alloys are typically divided into eight different series, ranging from 1xxx to 8xxx, with each series containing various grades. Below, we will provide a detailed explanation of the performance characteristics of aluminum alloys within each series and grade.
The performance of 1000 series aluminum alloys
The 1000 series aluminum alloys are over 99% pure aluminum with small amounts of other elements. 1060 and 1070 are noted for their excellent conductivity, while the 1100 series, known as commercial pure aluminum, is the softest among common alloys.
