Titanium metal properties

One. Lightness: The specific gravity of titanium is 4.51, which is about half of alloys such as stainless steel, cobalt, chromium, etc. It is much lighter than 16.3 of gold. It has obvious advantages when making earrings, necklaces and other jewelry. This advantage also reduces the designer's restrictions on jewelry materials, and can be used to make a lot of large and exaggerated shapes.

This advantage also reduces the designer's restrictions on jewelry materials, and can be used to make many large and exaggerated shapes. two. Titanium has good corrosion resistance: Titanium is an extremely active element that easily reacts with oxygen to form tio2, but the oxide film of several to tens of nanometers formed on the surface of titanium is extremely complete and dense, and has an instantaneous self-destruction after partial destruction. Repair ability, and stable in most environments, this is the theoretical basis of titanium's corrosion resistance. The advantage embodied in jewelry is that it does not corrode, does not change color, can maintain a good luster for a long time, and is not afraid of water. three. Good biocompatibility: Titanium's good corrosion resistance characteristics make it not affect its essence after long-term contact with people, and will not cause allergies. Now it has been widely used in the medical field. Such as: titanium bone plate, titanium hip joint and titanium knee joint, etc. Therefore, people who have an allergic reaction to metal can wear it with confidence. four. Titanium can be colored: Titanium metal has a very interesting feature. When titanium is placed in an electrolyte and a certain current is applied, its surface should be electrolyzed with an oxide film, and the thickness of the oxide film can determine the color change. No additional elements are required. The available colors are gold, black, blue, brown, flower and other colors. This feature of it makes jewelry design more colorful and fashionable. Fives. Titanium is not easy to deform and does not need to be reshaped: Titanium has high hardness and is not easy to deform, unlike ordinary gold and silver jewelry that needs to be reshaped after a period of time. The industry believes that the diversification of jewelry materials will be the general trend of the market. Titanium jewelry, known as the 'new focus of the century,' appeared in the jewelry markets of Wuhan and Changsha in Central China in mid-November. According to Dr. Yang Mingxing, deputy dean of the Jewelry School of China University of Geosciences (Wuhan), titanium is also called space metal. Titanium is a very special metal, very light in texture, but very tough and corrosion resistant. Unlike silver, it will blacken and retain its own color for life at room temperature. After adding electric current and chemical treatment, different colors will be produced. Yang Mingxing said that due to the above characteristics of titanium, its unique silver-gray tone has a good performance whether it is high-polished, mercerized, or matte. It is the most suitable jewelry metal besides the precious metals platinum and gold. However, due to the high technical requirements for titanium processing, it is difficult to cast and shape it with conventional equipment, and it is difficult to weld it with ordinary tools, so it is quite difficult to form a production scale.
