As an important component, copper alloy forgings are widely used in industry, aviation, aerospace and other fields, so it is very important to judge its quality and reliability. The following describes several common methods for judging the quality and reliability of copper alloy forgings.
- Visual check
Direct visual and hand inspection of the surface of copper alloy forgings can check whether there are obvious defects and quality problems on the surface. First of all, check whether the surface of the copper alloy forgings is smooth, whether the surface has obvious scratches and damage, and also check whether the color of the copper alloy forgings is consistent, whether there are pores or inclusions. - Size measurement
Dimensional measurement is one of the most basic methods to evaluate the quality of copper alloy forgings. Fully measure the size and shape of copper alloy forgings and compare design requirements to determine if the forgings meet production standards. If the size and shape of the copper alloy forging do not match the design requirements, it indicates that there is a quality problem. - Hardness test
The hardness test can be used to evaluate the pressure resistance and wear resistance of copper alloy forgings. The higher the hardness value, the harder the material of copper alloy forgings and the higher the reliability. Hardness testing can be performed by using a dedicated measuring instrument, such as a Rockwell or Brinell hardness tester. - Acoustic detection
Acoustic inspection uses ultrasonic technology to detect internal defects and quality problems in copper alloy forgings. It is a non-destructive testing method that can measure defects such as internal cracks, pores and holes of copper alloy forgings very accurately. - Metallographic analysis
Metallographic analysis is the observation and detection of the crystal structure inside the copper alloy forgings, which can determine whether the metallurgical structure of the copper alloy forgings is uniform and whether there is poor microstructure. This method is suitable for organic group, medium and low hardness alloy steel and other materials.
All in all, the above method is to judge the quality and reliability of copper alloy forgings commonly used methods, in the process of production and use have a wide range of applications, can determine whether the forgings meet the standards and requirements, but also for copper alloy forgings manufacturers and users are very valuable reference.
