Baijia.net specializes in copper alloy testing、 and our platform's testing institutions cover the entire testing industry. Online one-on-one service. The test report is delivered on time and with good quality、 and you can enjoy the report delivery service. On the Baijian platform、 customers can complete the inspection process online from ordering services、 submitting commission information、 and finally paying the inspection fee、 without leaving the house. Next、 I will briefly introduce the testing standards and process of Baijia.net for copper alloy testing
Introduction to copper and copper alloy testing: Check the microstructure of copper alloys and analyze defects. The metallographic examination of copper and copper alloys is mainly used to measure their grain size、 as well as to qualitatively and quantitatively measure the content of copper oxide to check its purity. Sometimes、 for specific brass、 it is necessary to determine the distribution of lead、 as this may affect the machining process. For cast copper alloys、 it is necessary to evaluate the microstructure and distribution of eutectic or lead、 as well as the presence of shrinkage or porosity
