Steel paper raw paper testing metal materials is an essential raw material for the development of China's society, with characteristics such as plasticity, durability, and hardness. In our daily life and production process, we often see various metal materials, such as steel, iron, copper, aluminum, tin, and alloys. However, for these metal materials, their quality varies. In addition, metal materials are affected by high temperature, high pressure, and other factors during storage and application, making it difficult to effectively guarantee their quality. If quality testing is not carried out, It will affect its application effect and thus affect the social development of our country. From this, it can be seen that it is very necessary to test the quality of metal materials.
