The pneumatic cylinder tube is made of aluminum alloy, which has low specific gravity, corrosion resistance, fast heat conduction, oil storage and so on.
Most of the engine blocks are made of aluminum alloy. From the point of view of use, the advantages of cast aluminum pneumatic cylinders are light weight, fuel saving and weight reduction. In the same displacement engine, the use of aluminum pneumatic cylinder engine can reduce about 20 kg. The weight of each car is reduced by 10%, and the fuel consumption can be reduced by 6% to 8%. According to the latest data, the weight of foreign cars has been reduced by 20% to 20% compared to the past. For example, Fox uses a complete aluminum alloy material that reduces body weight while improving engine cooling, increasing engine efficiency and extending life. From the perspective of oil savings, the advantages of cast aluminum engines in saving fuel have attracted too much attention.
However, the change in material cost is more costly. Due to the difference in material price and processing technology, the price of using an aluminum alloy cylinder engine will naturally be higher than that of a cast iron engine. At this point, it’s clear that the cast iron engine cylinder is dominating.
The pneumatic cylinder is made of aluminum or aluminum alloy due to low pressure pneumatic conveying, generally not higher than 0.8 mpa, and the aluminum alloy cylinder is full of pressure. The hydraulic transmission pressure is as high as 32 mpa or even higher, and the strength of the aluminum alloy material cannot be tolerated, so the main part of the hydraulic cylinder is made of steel.
Small computers mostly use aluminum alloys, because the working pressure is not very high, and there is little change in aluminum heating and oxidation, and large ship engines use other alloys
The hydraulic and pneumatic cylinder has a high pressure, and more oil conductive liquids, basically do not need to consider oxidation
Aluminum pneumatic cylinders(made by Autoair pneumatic cylinder tube) are lightweight, low cost, and can meet air tightness requirements. Because of the penetration ability of oil molecules, hydraulic cylinders are not easy to leak with steel.
