The material selection of aviation forgings needs to consider the following factors: strength and toughness: Aviation forgings are subjected to a high strength and high stress working environment, so the material needs to have sufficient strength and toughness to ensure that the parts do not occur plastic deformation or fracture during use. Wear resistance and corrosion resistance: Aviation forgings may be exposed to external factors such as particles, friction, and may also be subjected to corrosion by moisture, chemical media, etc. Therefore, the material needs to have good wear and corrosion resistance to ensure the long-term reliability of the parts. Weight: The aviation industry is very strict about weight, because reducing the weight of an aircraft can improve fuel economy and performance. Therefore, aviation forging materials usually need to have a lower density to reduce the weight of the parts themselves. Thermal stability and high temperature performance: Aviation forgings work in a high temperature environment, so the material needs to have good thermal stability and high temperature performance to ensure the strength and stability of the parts at high temperatures. Cost: The cost of aviation forging materials is also a factor to consider. The aviation industry has high requirements for the quality and reliability of materials, but also needs to consider cost effectiveness to ensure that the right materials are selected within a given budget. In addition, specific application scenarios and requirements will also affect the choice of aviation forging materials, such as temperature, pressure, vibration and other environmental factors, as well as the size and complexity of parts. In practical applications, according to these factors, the most suitable material is selected to meet the performance requirements. Commonly used aviation forging materials include titanium alloy, superalloy, aluminum alloy and stainless steel.
