1. 1xxx series are pure aluminum
2. The 2xxx series are aluminum copper alloys
3. 3xxx series are aluminum and manganese alloys
4. The 4xxx series are aluminum silicon alloys
5. The 5xxx series are aluminum and magnesium alloys
6. The 6xxx series are aluminum magnesium silicon alloys
7. The 7xxx series are aluminum and zinc alloys
Among the above aluminum and aluminum alloys, only pure aluminum, aluminum-magnesium alloy, aluminum-silicon-magnesium alloy and the aluminum-magnesium rare earth alloy after adding rare earth are commonly used as the conductor, that is, the tube bus.
B. For the power industry, the most important thing is to classify according to insulation conditions:
1. Exposed pillar insulated aluminum alloy tube bus (aluminum magnesium alloy, aluminum magnesium rare earth alloy)
2. Semi-insulated aluminum alloy tube bus (pure aluminum, aluminum magnesium alloy)
3. Fully insulated aluminum alloy tube bus (pure aluminum, aluminum magnesium alloy)
