With vacuum technology and computer applications, material titanium VAR method soon became titanium mature industrial production technology, and today the vast majority of titanium and its alloys ingots produced using this method. VAR method notable feature is the low power consumption, high melting rate and good quality reproducibility, VAR ingot smelting method has a good crystal structure and uniform chemical composition. Typically, finished ingot obtained by melting VAR method. Remelted at least twice. VAR method using titanium ingot production, process manufacturers around the world use similar, the difference lies in the use of different electrode preparation methods and equipment. Preparation of electrodes can be divided into three categories, one with the overall electrode feed continuous suppression medical titanium alloy of press parts, excluding the electrode welding processes: two monolithic electrode pressed into a consumable electrode welding. And by plasma welding or welding into one vacuum; the third is prepared using other casting melting electrodes.

The performance of titanium and titanium alloy medical titanium alloy shows its yield ratio (tensile strength / yield strength), represents titanium and titanium alloy materials during the molding of plastic deformation difference. Since the ratio of titanium yield limit and the elastic modulus is large, so that the resilience of titanium molding large.
Low temperature titanium and titanium alloy materials, its strength with decreasing temperature increase, but the plastic change is not large. material titanium Maintaining good ductility and toughness at low temperature -196-253 ℃, avoid the metal cold brittleness, is an ideal material for cryogenic vessels, tanks and other equipment.

Throughout the country, each year on medical titanium alloy imported medical devices and medical equipment, every year we do not know enough to spend hundreds of billions!
    Perhaps, to change this situation, we need to work too much respect. The Government must continue to introduce policies to guide, or is forced, to continuously improve the proportion of domestic applications, and cut off all kinds of unspoken rules of the interests of the chain; doctors, to change only the best regardless of the price of habit, and to guide the patient; patients to establish the confidence of domestic appliances and equipment, and personally, to support localization!
    This way, you can obviously not be done overnight,material titanium  but I believe that all the people in line with the interests of the road, no matter how much resistance, both will be able to widen the Taobao came out, micro letter also came out.
    Medical equipment, medical equipment, medical services in the next 5--10 years, must be a blue ocean! Shares of these industries must be firm long-term bullish, and never betray.
