Metal thermal reduction method to produce titanium sponge-like. Purity% (by mass) is generally 99.1 to 99.7. % Impurity element (mass) amount of 0.3 to 0.9% oxygen impurity element (mass) of 0.06 to 0.20, hardness (HB) of 100 to 157, depending on the purity to MHTi4 WHTiO into five levels.

Titanium alloy for manufacturing automatic rifle
The strength of titanium, titanium tensile strength up to 180kg/mm2. Some of the strength of the steel is higher than that of titanium alloy, but the titanium alloy than strength (tensile strength and density ratio) was more than the high quality steel. Titanium alloy with heat resistant strength, low temperature toughness and fracture toughness is good, so it is much used for aircraft engine parts and rocket, missile structure. Titanium alloy can also be used as a fuel and oxidizer tank and high pressure vessel. Now has a titanium alloy for manufacturing automatic rifle, the launch tube of mortar base plate and recoilless gun. In the oil industry titanium
coil mainly for various vessel, reactor, heat exchanger, distillation tower, pipe, pump and valve etc.. Titanium can be used as electrode and a power station condenser and environmental pollution control device. Titanium nickel shape memory alloy has been widely used in instruments. In the medical treatment, titanium can be used as artificial bones and various utensils. Titanium or steelmaking deoxidizer and stainless steel and alloy steel components. Titanium dioxide pigment and paint is a good raw material. Titanium carbide, carbon (hydrogen) is a new type of titanium carbide materials. Titanium nitride color close to gold, widely used in decoration. Titanium and titanium alloys used in large quantities for the aviation industry, "space metal" known; in addition, is widely used in the shipbuilding industry, chemical industry, titanium
sheet machinery parts manufacturing, telecommunications equipment, hard alloy, etc.. In addition, because the titanium alloy also has good compatibility with the human body, so the titanium alloy can also be used for artificial bone. The corrosion resistance of titanium zirconium nitrate and hydrogen titanium zirconium oxide is a kind of application in the atomic energy industry and used as a corrosion resistant chemical materials under high temperature and pressure, but in the lively after sodium solution. Then, the titanium hydroxide solution added live wave zirconium nitrate solution, will find that to shut sb. titanium zirconium nitrate. As you can see, there are the obvious layered graph, the above is zirconium nitrate, below is the titanium hydroxide. We know, titanium hydroxide is less than the density of zirconium nitrate, but can still maintain the obvious stratification, and zirconium nitrate stay in the upper, which proves that the corrosion resistance of titanium. According to the experiment, titanium into the ocean of annual 20~50 won't be corroded.
