There is no doubt that metal detectors will detect titanium in most cases. However. the detection may be affected by the size of the titanium object. the sensitivity of the metal detector itself. and the calibration of the detector.

Yes, it is possible for some individuals to have a sensitivity or allergic reaction to titanium dioxide, although it is considered relatively uncommon. Reactions can include skin rashes or irritation, and in more severe cases, difficulty breathing. However, titanium dioxide is generally considered safe and is commonly used in a wide variety of products, from sunscreen to food and cosmetic products. But, like any substance, it's always possible for someone to develop a sensitivity to it. If you suspect you're having an allergic reaction to a product containing titanium dioxide, contact a healthcare professional.

Titanium belongs to the Transition Metals group in the periodic table, specifically located in Group 4 alongside zirconium, hafnium, and rutherfordium. Transition metals are characterized by their ability to form variable oxidation states, their excellent conductance of electricity and heat, formidable strength, and resistance to corrosion. Titanium, in particular, is celebrated for its high strength-to-density ratio, being as strong as steel but about 45% lighter, and exceedingly resistant to corrosion from sea water, aqua regia, and chlorine. Its properties make it an invaluable material in aerospace, military, automotive, and medical industries, where its performance can significantly outweigh concerns about its higher cost compared to other metals.
