Titanium is biocompatible (often referred to as hypoallergenic), or non-toxic to the human body. Similarly, titanium rings will not react with wearers who suffer allergies to other jewelry materials. It is highly resistant to most causes of corrosion, including sea water, chlorine (in water), and some acids. It is soluble in concentrated acids, however. Titanium rings are therefore practical jewelry for those who regularly swim in the ocean or chlorinated pools. This is in contrast to some traditional jewelry materials, such as silver, brass, and bronze, which are prone to tarnish or other deterioration. Titanium rings generally have higher fatigue resistance and strength-to-weight ratios than most other metals. They are only slightly more difficult to cut off in case of emergency than for gold rings; titanium is comparable to steel in its resistance to sawing.
