Titanium is really strong, more so than other metals. So much so to where titanium is as strong as steel. In addition to being extremely durable, it’s very lightweight, making it comfortable to wear as a ring and on other jewelry. Its durability to weight ratio makes titanium an excellent choice for aircrafts as you need something extremely durable but also lightweight for aerodynamics.
Most titanium men’s wedding bands you’ll find are 99% pure aircraft grade titanium. A titanium wedding band of that quality will last a lifetime as long as its properly maintained.Another benefit of titanium is it doesn’t tarnish easily. Unlike other metals, titanium doesn’t tarnish easily from soil, air, or salt. Since it’s a poor conductor of electricity and heat, it’s a safe ring to wear all day.
Keep in mind, titanium isn’t completely scratch-proof, though it is more scratch-resistant than most metals. If your titanium band gets scratches, it's a pretty easy DIY fix or you can simply take your ring to a jeweler where they can buff out the scratches.
