Product introduction
Aluminum turbine is a turbine device made of high-strength aluminum alloy. It is widely used in mechanical equipment in the fields of aerospace, automobile manufacturing, industrial machinery, etc. Its main function is to convert the energy of fluid or gas into mechanical energy for driving generators, compressors, pumps or other mechanical devices.
Product features
High Strength
The tensile strength of aluminum turbine can reach 450-550MPa, while the tensile strength of ordinary cast iron is only 200-300MPa. This high strength enables aluminum turbine to maintain structural stability without deformation or damage even at high speeds exceeding 10,000 revolutions per minute or when subjected to centrifugal forces of 50-100 times its own weight.
Lightweight
The density of aluminum alloy is about 2.7g/cm³, which is only one-third of the 7.8g/cm³ of steel. Compared with traditional steel or cast iron turbines, aluminum turbines are 30%-50% lighter. For the aerospace and automotive industries, it can significantly reduce operating costs and reduce carbon emissions. For example, for every 1kg reduction in turbine weight, the aircraft engine can save about 0.3-0.5 liters of fuel per hour.
Corrosion Resistance
The surface of aluminum can automatically form an oxide film to isolate external oxygen or corrosive substances. Therefore, in an environment with a humidity of 85% and a sodium chloride concentration of 5% (simulating marine atmospheric conditions), the corrosion rate of aluminum turbines is less than 0.05mm/year, which is one-tenth of that of steel turbines. This makes aluminum turbines particularly suitable for long-term use in marine equipment, coastal industrial facilities and chemical machinery, which not only reduces performance degradation caused by corrosion, but also extends service life.
Good Thermal Conductivity
The thermal conductivity of aluminum is as high as 200-237W/(m·K), which is more than 4 times that of steel (about 50W/(m·K)). This high thermal conductivity enables aluminum turbines to quickly dissipate heat during operation, reducing component temperature by about 15%-20%, effectively reducing thermal stress concentration, and avoiding local material softening or fatigue failure.
