Why are pneumatic cylinder pipes made of aluminum?

The cylinder tube is made of aluminum alloy, which has the characteristics of low specific gravity, corrosion resistance, fast thermal conductivity, and oil storage.

Most engine cylinder blocks are made of aluminum alloy. From a usage perspective, the advantages of cast aluminum cylinders are light weight, fuel savings, and weight reduction. In engines of the same displacement, using aluminum cylinder engines can reduce approximately 20kg. The weight of each vehicle can be reduced by 10%, and fuel consumption can be reduced by 6% to 8%. According to the latest data, the weight of foreign cars has decreased by 20% to 20% compared to the past. For example, Fox used a complete aluminum alloy material to improve engine cooling, increase engine efficiency, and extend lifespan while reducing vehicle weight. From the perspective of fuel efficiency, the advantages of cast aluminum engines in fuel saving have attracted too much attention.
