How to determine if the screw is made of titanium material!

To determine whether the screw is made of titanium material, the following methods can be referred to:
1. Appearance recognition: Observe the appearance of the screw. Pure titanium screws and titanium alloy screws are similar to traditional stainless steel, copper, and iron screws, but high-end series titanium screws can reach higher levels. Its appearance is beautiful, sometimes even emitting a cool glow like a craft. Compared to iron screws and copper screws, titanium screws appear brighter with a cool glow.
2. Scratch test: In uncertain situations, gently scratch the screw on the white ceramic. If the screw is made of titanium, it will leave gray scratches on white porcelain. Stainless steel will not leave scratches on white porcelain. However, it should be noted that some titanium products now undergo special hardening treatment on the head of the product for better user experience, so that scratches are no longer easily left.
3. Chemical testing: This is a more accurate method. The composition of materials can be determined through chemical reactions. For example, using nitric acid testing, pure titanium will instantly produce bubbles.
4. Price judgment: Due to the relatively high cost of titanium as a raw material for screws, price is also a basis for judgment. If the price of the screw is found to be abnormally low, then it may not be a genuine titanium screw.
It should be noted that there are mainly two types of titanium screws on the market: pure titanium and titanium alloy. Pure titanium has good flexibility and antioxidant properties. And titanium alloy is made by mixing titanium with other metals to enhance its specific properties. When selecting and using screws, one should determine the appropriate material based on their actual needs.
