Three characteristics of titanium jewelry Aerospace titanium castings

1, the essential characteristics: Light: the proportion of titanium is 4.51, about titanium companies stainless steel, half of cobalt, chromium and other alloys, it is much lighter Aerospace titanium castings than gold 16.3, in making earrings, necklaces and other jewelry when obvious advantages. Titanium has good corrosion resistance: Titanium is a very active element, easily react with oxygen to produce Tio2, but several to several tens nm oxide film formed on the surface of titanium is extremely compact complete, After having the ability to self-repair local damage in the moment, and is stable in most environments, this is the theoretical basis of the corrosion resistance of titanium. Its advantage is reflected in the jewelry is Non-corrosive, not color, can long maintain a good luster, and is not afraid of water. Titanium can be colored: Titanium metal has a very interesting feature, titanium placed on certain current through the electrolyte, the surface should be based on the electrolysis will be a layer of oxide film, and the thickness of titanium precision casting the oxide film can be Decided to change the color, but also no external element. Now do the colors are gold, black, blue, brown, flowers and other colors. This feature makes it more colorful and more fashion jewelry design. Titanium is not easy deformation, do not re-shaping: high titanium hardness, not easy to deformation, unlike ordinary wear gold and silver jewelry, etc. After a period of time need to re-shaping. 2, stylish features: New Materials logo: titanium jewelry is new material appears to break the traditional, old gold and silver jewelry jewelry industry domination flag. In addition to decorative jewelry, has become the status, identity A symbol, as a third titanium into jewelry jewelry industry has added more healthy, elegant and stylish charm. Female Spirit Symbol: titanium (Ti) --- silver-gray metal, the proportion of 4.5, melting point 1668 ° C, titanium texture is very light, but very tough, on behalf of urban women and lightweight, yet strong aesthetic Tough. Male spirit symbol: 1795 German scientist Bruce carats found in the study of rutile titanium, he sons of the soil of ancient Greek mythology, the Titans (titan) to name, and "Thailand Tan Spirit "is the same thing with courage, strength and its natural texture like Titan, like heroism, highlighting the urban men like sons of the soil" Titan "spirit. Love symbol mark: Titanium with corrosion-resistant, it will not be like the silver will turn black, at room temperature for life to maintain their color. Couples jewelry represents love, loyalty, betrayal and never consistently The supreme quality. 3, health characteristics: Titanium on the human body without any damage and the first to meet the health and longevity of aerospace castings the pursuit, medically proved: Titanium organs can be permanently implanted in the human body, showing its harmless to the human body God Odd. Extremely loyal and good biocompatibility make titanium jewelry stability after prolonged contact with the human body does not produce allergies, skin, nerves and taste are not adversely affected, there If you are ambiguous lover, so it has a hat: biophile metals. Therefore it is absolutely harmless for skin allergies modern people can become their first choice.

Aerospace titanium castings Meaning of titanium and its effectiveness on the human body

Titanium is a hard, high corrosion stability safety, metal hypoallergenic, far more than the hardness of Aerospace titanium castings silver and platinum, and is three times that of steel. Titanium is named according to its super Metallic come, TIANIUM (titanium English) refers to as the Titans (European mythology resolute character of God) as hard and unyielding. Titanium material not only high hardness, corrosion resistance comparable degree nor a general metal. King of Corruption "aqua regia" can be said to be the bane of the metal, but it does not pose any harm to titanium. So is Widely used in aerospace, military, medical device equipment in. On the titanium precision casting other hand, titanium is the metal most friendly with humans. Its stability so that the body does not reject them completely (in vivo In vitro are not allergic), so in surgical implants used in the performance of titanium correction tools are the best, the price is highest. Since titanium has a variety of excellent features, many Western young people are choosing to do with the carrier to produce titanium wedding ring, with a large diamond, makes titanium ring that symbolizes elegance and rock Love. Titanium on the human body effects: Titanium products by regulating the body current, so that the temperature rises, reaching the spirit of relaxation, muscle relaxation, improve the effect. Increase the heat will relax the muscles and stimulate aerospace castings blood flow Move, increased blood flow helps your body to better eliminate blood from the effects of pain and fatigue factor.

Aerospace titanium castings Talk titanium crystal

Titanium crystal yield scarce, a good friend, called Crystal the most. Wearing titanium crystal to prevent Aerospace titanium castings interference supernatural or make your own gas field are less likely to come into contact with strengthening the negative energy, hang on The car is more evil fierce drive results. Wang Qi enhance titanium titanium precision casting crystal, elegant strokes. Wearing titanium crystal friends often need help to make the right decisions informed decisions, but also inspire personal courage, boldness. Titanium crystal with the main financial, partial Wealth, popularity, good fortune, health, anti-villain aerospace castings of the six main energy.

Porcelain teeth are made of pure titanium What are the benefits Aerospace titanium castings

For titanium porcelain teeth how much you have to know it, is a titanium metal implant into the body of modern medicine most widely used metals, accounting for more than 80%; due to Aerospace titanium castings titanium with no human contact sensitization, carcinogenicity , The distortion caused by the phenomenon, with bone tissue, epithelium, connective tissue good combination, so it is best biocompatible metallic materials; same titanium taken in the field of production of dental prosthesis Got great results: titanium porcelain teeth, titanium steel care In addition to titanium dental porcelain affinity with excellent organization, it also has the following advantages: 1, light weight titanium porcelain teeth: a small proportion of titanium, titanium porcelain teeth proportion of its gold 1/4, 1/2 cobalt-chromium alloy, titanium thus making porcelain teeth will be much titanium precision casting lighter weight can To reduce the burden on the remaining tissue in the mouth, titanium porcelain teeth also has a better comfort. 2, low thermal conductivity: crowns made with titanium, titanium porcelain teeth can better isolate hot and cold stimulation, help protect the pulp, titanium porcelain teeth eating hot or cold foods when not There will be a sense of pain. 3, no taste disturbance: Titanium has good stability, not titanium metal porcelain teeth in the mouth feel of the taste, the taste does not cause interference. 4, the transmission X-ray: titanium titanium porcelain teeth on a semi-transmissive X-ray, wearing crowns made of pure titanium, the X-line, you can check whether the decay inside the crown, so early detection , Early treatment, which is aerospace castings the other metal materials for the production of titanium porcelain denture teeth do not have advantages.
