The turbine body is the core component of the turbine or turbocharger, responsible for converting the kinetic energy of the airflow into mechanical energy. Thereby driving various mechanical equipment or improving the efficiency of internal combustion engines. The casing of the turbine body is usually made of high-strength, high-temperature-resistant materials to protect the internal blades and mechanical structure. And ensure its stable operation in high temperature and high pressure environment. The turbine body usually needs to withstand high temperatures, high pressures and high rotational speeds, so the selection of materials is crucial. Aluminum metal: Aluminum is lightweight, high-strength, corrosion-resistant, beautiful, easy to dissipate heat, easy to form, easy to process, easy to conduct electricity, non-magnetic, Easy to handle, improved reflectivity, diversified surface colors and other excellent properties. Gravity casting: suitable for manufacturing turbine body parts with complex shapes and precise structures. Gravity casting enables precise control of part size and shape, and provide excellent surface quality.
