Applications of Titanium, Cobalt and Tungsten metal

Titanium was originally used for industrial purposes, but titanium has a density of only 4.5 and is light in weight. It has long been a popular choice for jewellery. Compared to platinum and gold, jewellery made of titanium is more distinctive. It is limited to making rings, and other complex styles of jewellery made from it are more novel and unique, and modern and fashionable.

Titanium is originally silvery white, but it is placed in the electrolyte to pass an electric current. The surface of the titanium will be electrolyzed to form an oxide film. The thickness of the oxide film will be different and the color will be different. Moreover, titanium metal is not allergic at all, and it is not easy to be scratched, but it is difficult to change the ring made of titanium metal.

For men, cobalt, tungsten, and stainless steel are popular in the design of engagement rings, but they are rarely used in women's jewelry. Cobalt is a silver-white metal that is stable in the air and has a weight that is greater than other metals (such as titanium). Its biggest advantage is that it is quite scratch-proof, and if the ring is not suitable, it is quite easy to change the size of the circle. The metal tungsten is steel gray or silver white, and the hardness is four times that of titanium. The ring can be made in both white and black, and is not allergic to titanium. However, due to its extremely high hardness, it is difficult to repair.
