aluminum bus bar vs copper

Due to the rising price of electrolytic copper material, the price of copper bus is also increasing, and the cost of engineering power distribution is also increasing. At present, copper bus is the main bus product in the market. Can we find a product with the same performance as copper bus but lower price than copper bus?
 
The answer is yes. Aluminum bus bar can be used as a substitute for copper bus because of its low price and excellent performance. At present, the unit price of aluminum bus bar is close to 50% of that of copper bus. Therefore, under the same performance, in order to reduce the cost, aluminum bus bar can be selected to replace copper bus.
 
 
The 1070 6101 aluminum bus bar produced by Henan signi Aluminum Co., Ltd. adopts aluminum bars with conductivity ≥ 61%. Although the conductivity is lower than that of copper bus bars, it also reaches the conductivity of some copper bus bars in the market, and the sectional area of aluminum bus bars increases accordingly. Therefore, in terms of safety, the safety performance of bus will not be affected by the change of material.
 
 
The same weight case download flow analysis: the density of aluminum is 2.7 g / cm3, and the density of copper is 8.9 g / cm3. The density of copper is about 3.3 times that of aluminum. Therefore, under the same weight, the current carrying capacity of aluminum bus bar is far greater than that of copper. For example, at 1600A, the current carrying capacity per unit weight of aluminum is 2.67 times that of copper. This greatly reduces the weight of the bus. It is beneficial to reduce the building load and facilitate the installation on the building.
