1. Analysis of chemical composition
We can first cut a part for chemical composition analysis through authoritative testing institutions. The impurity element content of commercial pure titanium does not exceed 0.1 percent , and the titanium alloy plate will have obvious differences according to the alloy ratio.
2. Hardness analysis
The hardness of pure titanium plate is 1/2 times that of ordinary steel plate. The hardness of industrial pure titanium is usually less than 120-290 Brinell hardness, the higher the purity, the closer the Brinell hardness is to 120 Brinell. The hardness of the highest purity grade of industrial pure titanium is usually less than 120 (Brinell du), and the hardness of other industrial pure titanium is 200--295 (Brinell). The hardness of pure titanium castings is 200-220 (Brinell). The hardness value of titanium alloy in the annealed state is 32-38 (Rockwell, C calibration), which is equivalent to 298-349 Brinell hardness. The as-cast and titanium Ti-6AL-4V had a hardness of 320 (Brinell) and the low interstitial impurity Ti-6AL-4V casting had a hardness of 310 (Brinell).
3. With the help of professional equipment
Now spectrometers or X-ray fluorescence spectrometers and thermoelectric comparators can also quickly distinguish pure titanium plates from titanium alloy plates.
