Tungsten carbide, also referred to simply as tungsten, is a very hard, strong and durable metal. It's also quite heavy. Tungsten is highly scratch resistant. Unlike gold, platinum and even titanium, tungsten rings do not scratch with everyday wear like the other metals do.
It is technically possible to scratch tungsten, though only with objects that are harder than tungsten. So that leaves diamonds, sapphires, rubies and ceramic. Though unless you dragged the tip of a loose diamond along the tungsten, the metal will stay scratch resistant. Having a wedding band that's scratch resistant offers a lot of advantages.
Tungsten always looks new and bright and shiny. Tungsten offers what's referred to as a permanent polish, which means that it doesn't need to be re-polished. So, it doesn't need the polishing maintenance that gold, platinum and titanium rings do.
Tungsten stands up to the wear that even the roughest husbands can dish-out, making it a popular choice for men's wedding rings. Tungsten has an appealing color which almost all men like. The tungsten color is a grey-white color, similar to that of white gold or titanium.
Tungsten is particularly popular in men's wedding rings. The range of tungsten jewellery is generally more restricted than for other metals. Tungsten rings cannot be resized (as tungsten can't be cut and resoldered), so it's important to have your finger size accurately measured before buying a tungsten ring.
