In metallurgy, titanium gold (Ti-Au or Au-Ti) refers to an alloy consisting of titanium and gold.Such alloys are used in dentistry, [1] [2] ceramics and jewelry. [3] Like many other alloys, titanium gold alloys have a higher yield strength, tensile strength, hardness, and magnetism than either of its constituent metals.
It has a chemical composition of 6% aluminum, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen, and the remainder titanium. [19] It is significantly stronger than commercially pure titanium (grades 1-4) while having the same stiffness and thermal properties (excluding thermal conductivity, which is about 60% lower in Grade 5 Ti than in ...
The resulting alloy is roughly the hardness of 14-karat gold and is more durable than pure 24-karat gold. [122] Titanium's durability, light weight, and dent and corrosion resistance make it useful for watch cases. [115] Some artists work with titanium to produce sculptures, decorative objects and furniture. [123]
Its density, similar to that of gold, allows tungsten to be used in jewelry as an alternative to gold or platinum. [21] [100] Metallic tungsten is hypoallergenic, and is harder than gold alloys (though not as hard as tungsten carbide), making it useful for rings that will resist scratching, especially in designs with a brushed finish.

Standard electrode potentials offer a quantitative measure of the power of a reducing agent, rather than the qualitative considerations of other reactive series. However, they are only valid for standard conditions: in particular, they only apply to reactions in aqueous solution. Even with this proviso, the electrode potentials of lithium and ...
Yet there's a shiny glimmer amidst the investment dross, a metal that for the moment appears to be a winning alternative to the favorite of King Midas: Behold titanium, whose outlook is robust ...
