Comparison of three conductor materials

Comparison of three conductor materials: copper bar, copper aluminum composite bar and aluminum bar:
Copper bar, copper aluminum composite bar and aluminum bar, these three kinds of conductor materials have their own advantages in electrical performance, and their conductivity, physical properties, cost and application scenarios are significantly different.

Specifically, the conductivity of copper busbar ranked second, second only to silver, and its reliability was also quite excellent. However, the weight of copper is relatively large, the price is relatively high, and the price is on the rise. Aluminum busbar is favored for its lightweight texture and friendly price, and its conductivity is second only to copper in pure metal. However, there are some inherent defects in the lap joint of aluminum bus, which may affect its use effect. The copper aluminum composite row combines the advantages of copper and aluminum, but it may still be inferior to pure copper or pure aluminum in some aspects.

Each of the three has its own advantages and disadvantages: the copper bar has the best performance but high cost; the aluminum bar is economical and light but not reliable; the copper aluminum composite bar balances performance, cost and weight, and becomes an ideal choice for medium and high-end applications
