In order to explore the feasibility of tungsten filament as biomedical metal material,this article conducted a series of performance tests on two different thicknesses of black tungsten filament and two different thicknesses of white tungsten filament.It mainly tested the basic physical properties of the tungsten filament including the longitudinal cross-section of the fiber,the fiber diameter,the mechanical properties of the fiber and the biodegradability,and analyzed the results.The results showed that the breaking force of tungsten filament was about 3000MPa.And whether it was black tungsten filament or white tungsten filament,the larger the diameter,the greater the breaking force,and the breaking strength of the tungsten filament was much larger than the breaking strength of the steel wire.The larger the diameter of the tungsten filament,the slower the degradation rate.During the two months,the mass loss rate of the thick black tungsten filament was 59.40％,thin black tungsten filament was 83.88％,thick white tungsten filament was 47.39％,thin white tungsten filament was 72.29％,the degradation rate of thick tungsten wire was nearly half of the thin,and degradation mainly occured in the first months.
