Tantalum has a series of excellent properties, such as high melting point, low steam pressure, good cold working performance, high chemical stability and strong corrosion resistance. It is used in the production of various alloys with high melting point, strength and ductility, as well as hard alloys used in the manufacture of metalworking equipment. Tantalum can be used as a structural material for the combustion chamber of aircraft engines. Tantalum tungsten, tantalum-Tungsten-Hafnium, tantalum and hafnium alloys are used as fire.
Because tantalum take the response of active oxygen, therefore must give way is even a little is end in the atmosphere of the atmosphere heat treatment as a result, the basic all end in the annealing is all are highly and furnace gas tightness must also be very high as long as it is, tantalum hot place a few temperature is 950 ~ 1300 ℃, take use of tantalum alloy few tantalum is that the temperature within the boundaries don't attack phase change, only used for annealing heat treatment, so the heating temperatures and cooling fast it doesn't matter not the same as the dealer is on the basis of his performance is good or bad to set the promotions, along the line if the distance is near, In theory, there is no problem with alloys made of titanium and tantalum because both metals are biocompatible and their mechanical properties are due to pure titanium
Basic all annealing is in highly stopped, and the furnace gas tightness is sure on the high side who, tantalum of heat treatment temperature is 950 ~ 1300 ℃, usually tantalum take usually adopt tantalum alloy are not attack phase change in the temperature category, heat treatment is only used for annealing, heating temperature and rapid cooling is not important pure metal waste, usually after chemical cleaning by vacuum melting, electron beam melting and hydrogenated powder fire hearth smelting methods, such as long-term recovery of the alloy can be something as hard metal processing material, high temperature alloy and build system, used in jet engine, chemical testing equipment.
The owner of Chaoda has bought out 1\3 tantalum powder in the world. The reaction tantalum target material in chemical medium is at a high price. Tantalum can produce a layer of surface oxide film quickly in almost any other environment and is tightly coated on its metal substrate. The film is thin and extremely fine, which is impermeable to almost all media.
