The tantalum–tungsten alloys typically vary in their percentage of tungsten. Some common variants are: (Ta – 2.5% W) → also called 'tantaloy 63 metal.' The percentage of tungsten is about 2 to 3% and includes 0.5% of niobium. This alloy has a good resistance to corrosion and performs well at high temperatures.
Titanium rings are jewelry rings or bands which have been primarily constructed from titanium. The actual compositions of titanium can vary, such as "commercial pure" (99.2% titanium) or "aircraft grade" (primarily, 90% titanium, 6% aluminum, 4% vanadium), and titanium rings are often crafted in combination with other materials, such as gemstones and traditional jewelry metals.
Titanium alloys are alloys that contain a mixture of titanium and other chemical elements. Such alloys have very high tensile strength and toughness (even at extreme temperatures). They are light in weight, have extraordinary corrosion resistance and the ability to withstand extreme temperatures.
A pair of wedding rings. A wedding ring or wedding band is a finger ring that indicates that its wearer is married. [1] It is usually forged from metal, traditionally gold or another precious metal. Rings were used in ancient Rome during marriage. [2] In western culture, a wedding ring is typically worn on the base of the left ring finger.
Tantalum was extensively used in the production of ultra high frequency electron tubes for radio transmitters. Tantalum is capable of capturing oxygen and nitrogen by forming nitrides and oxides and therefore helped to sustain the high vacuum needed for the tubes when used for internal parts such as grids and plates.

[citation needed] A trio ring set includes a women's engagement ring, a women's wedding band, and a men's wedding band. These sets often have matching rings and are lower in price. [citation needed] In Nordic countries, engagement rings are worn by both men and women. Traditionally they are plain gold bands, although more ornate designs and ...
