How to distinguish pure titanium frames, mainly from the following aspects, that is, check the weight, check whether there is a magnetic reaction, check the structure of the hinge, check with chemical reagents, test with conductivity index. You can place the magnet on the table and lean the frame back. If there is a magnetic reaction, it is not a pure titanium frame. In addition, because different metals have different electrical conductivity, the conductivity index can also be used to determine whether it is pure titanium metal.
