According to the content of aluminum and other elements in the aluminum alloy:
(1) Pure aluminum: Pure aluminum is divided into three categories according to its purity: high-purity aluminum, industrial high-purity aluminum and industrial-purity aluminum. Welding is mainly industrial pure aluminum, the purity of industrial pure aluminum is 99.7% to 98.8%, and its grades are L1. L2. L3. L4. L5. L6 and other six.
(2) Aluminum alloy: Alloy is obtained by adding alloying elements to pure aluminum. According to the processing characteristics of aluminum alloys, they can be divided into two types: deformed aluminum alloys and cast aluminum alloys. The deformed aluminum alloy has good plasticity and is suitable for pressure processing.
Deformed aluminum alloys can be divided into four types: anti-rust aluminum (LF), hard aluminum (LY), super hard aluminum (LC) and forged aluminum (LD) according to their performance characteristics and uses. Cast aluminum alloys are divided into four types: aluminum-silicon series (AL-Si), aluminum-copper series (Al-Cu), aluminum-magnesium series (Al-Mg) and aluminum-zinc series (Al-Zn) according to the main alloying elements added. .
The main aluminum alloy grades are: 1024.2011.6060, 6063.6061.6082.7075
