How to ensure the quality of tungsten plates?

Quality assurance of tungsten plates involves multiple inspection steps. Chemical analysis is performed using techniques such as inductively coupled plasma mass spectrometry (ICP-MS) or X-ray fluorescence (XRF) to verify the purity of the material and detect any trace impurities.
Mechanical testing includes tensile strength, hardness, and fatigue testing to ensure that the tungsten plates meet the mechanical properties required for their intended applications. Non-destructive testing methods such as ultrasonic testing and X-ray radiography are used to detect internal defects such as cracks or porosity.
In addition, the surface quality of tungsten plates also needs to be carefully inspected, including smoothness, flatness, and any surface defects, as these factors affect the performance of tungsten plates in various applications, especially in precision industries such as semiconductors and aerospace.
