The internationally registered aluminum alloy grades consist of more than 1000, each of which has a variety of states and has a very different effect in terms of function and performance. It is necessary to make reasonable material selection according to the performance requirements of the products, the use environment, the processing engineering, the priority of performance and other factors.
Commonly used aluminum alloy grades are generally composed of several numbers and English letters, each of which has a different meaning. The following is a detailed explanation
The meaning of the 4 nunbers of aluminum sheet grade
The first digit indicates the main chemical elements contained
The second digit indicates the number of modifications
Series 1 The third and fourth digits indicate the aluminum content.
Series 2-8 The third and fourth digits have no special meaning and are only used to distinguish other alloys.
Standard is a combination of two standards: Chemical composition standard + plate standard
Aluminum is divided into pure aluminum, hard aluminum, super hard aluminum, rust-proof aluminum and wrought aluminum.
