Titanium is a metal having a high degree of chemical activity. However, it emerged in many corrosive media particularly excellent corrosion resistance. The reason is titanium and has a good affinity for oxygen, react with oxygen to produce highly strong and dense layer of oxide film on the surface of the blunt.

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.

The reason for the use of titanium and titanium alloy body attachment Sunrui titanium valve
Production rod attachment denture material covering the earliest uses a gold alloy, which has good
mechanical properties , suitable elastic properties . Persist in the mouth , with good corrosion resistance,
and non-toxic side effects, titanium tube in the developed countries is still being used as the main material attached to
the production role . However , due to the rising price of gold production costs , increasing denture ,
increased the financial burden on patients. Therefore, it uses a number of non- precious metals attachment ,
such as ceramic alloys , but when they are used for dental restoration materials , due to the corrosion of
metals produced , will be Titanium precision castings released within the alloy elements in the form of ions into the oral environment
and local organizations contacting cells or produce different biological effects , especially when using a
different alloy prosthesis , since the saliva in the oral cavity as an electrolyte to form the source cell,
a current corrosion .
Therefore, the use of titanium and titanium abutments for implants , making the material attached to the
upper part of the body structure Titanium castings should also adopt the same kind of alloy , to prevent the generation of
electrochemical corrosion .

Cast titanium tubes embedded material performance requirements
Medicine to obtain a good casting cast titanium tube size to the embedding material hardening and
thermal expansion compensation titanium alloy pump expanded metal casting shrinkage is the most commonly used method. Titanium
tube casting line shrinkage of 0.9-1.0%, the total expansion required when casting titanium tubes embedded
material must be able to titanium tube compensate for the contraction of the range of metal and titanium tube system in
principle, with the cast of embedding material not mix. Therefore, the choice of cast titanium with embedded
material conditions must have the following conditions:
1. Rarely react with titanium.
2 to obtain good surface properties.
3 castings are not titanium casting contaminated.
4 titanium tube shrinkage compensated moderate swell.
