The elastic modulus of tungsten wire is an important physical parameter that describes the ability of tungsten wire to resist elastic deformation when subjected to external force. Regarding the elastic modulus of tungsten wire, different data may give slightly different values, which is mainly due to the differences in the purity, preparation process, test conditions and other factors of the tungsten wire. But in general, the elastic modulus of tungsten wire is usually high, which makes it have excellent stiffness and tensile strength in many applications.
Generally speaking, the elastic modulus of tungsten wire is about 350~411GPa. For example, some data indicate that the elastic modulus of tungsten wire is about 360GPa, while others may give 35000~38000MPa (i.e. 35~38GPa) or higher. These differences may be caused by differences in test methods, sample preparation and data processing.
It is worth noting that the elastic modulus of tungsten wire is not fixed, and it will be affected by many factors. For example, as the temperature increases, the elastic modulus of tungsten wire usually decreases. In addition, the purity of tungsten wire will also affect its elastic modulus. Tungsten wire with higher purity usually has a larger elastic modulus. Therefore, in practical applications, it is necessary to select appropriate tungsten wire materials and preparation processes according to the specific use environment and requirements.
