professional titanium products manufacturer

China has become an aging country, the number of people who is suffering from various joints’ diseases is increasing, so the demand for artificial joints is also increasing. It is said that from the relevant departments each year the number of people who need to change the joints in our country is up to 300000.
The application of artificial joints has been 40 - 50 years, now it has been widely accepted. The artificial joint materials used in the earliest time, such as polypropylene, organic glass have low strength and poor biocompatibility and is easy to fold. Later the material switched to stainless steel, but the proportion of stainless steel is bigger, about 2 times the weight of the human body, and it will appear corrosion and fracture under the action of receptor fluid in body.
For this issues of frequent infection, loosening and dislocation, we can draw such a conclusion that artificial joints and artificial bone substitute materials should include these basic properties: light high strength material, biocompatibility, corrosion resistance, repeated stress caused by fatigue, litter wear and so on.
So in this case, the titanium and titanium alloy stand out in the common metal materials.
Titanium and titanium alloy is a kind of ideal artificial joint material, because of its small specific gravity (close to human bone), great strength, good mechanical properties and excellent corrosion resistance.
The study of artificial bone and artificial joint in China began in the mid 1970s, at present, it has made gratifying achievements that can produce more than 10000 pieces of products and more than 30 varieties every year, some products are also exported to all over the world. With the development of national economy and the improving of people's living standards, more and more people demand for limb correction and cosmetic technology. Therefore, the development of medical implant materials in our country and even the world is promising. Titanium is known as the metal materials with the best biological properties, in the future, with the technological improvements of the powder metallurgy, casting, welding, precision casting and so on, titanium artificial joint has a very good development prospects.
