The historical development of titanium

In 1947, people began in the factory smelting titanium. That year, output was 2 tons. In 1955, the surge in production to 20000 tons. In 1972, the annual output reached 200000 tons. The yield strength of titanium are higher than steel, but it weighs almost only half the same volume of steel, Titanium Sheet Metal Price although slightly heavier than aluminum point, yield strength of it is 2 times larger than the aluminum. Titanium ratio strength higher than aluminum and steel, modulus and aluminum, steel is very close to the. In the universe of rocket and missile, a large number of titanium instead of iron. According to statistics, the world every year for the universe navigate titanium bar stock, has reached more than one thousand tons. Very fine titanium powder, or rocket good fuel, so ti is known as cosmic space metal, metal.
Titanium at elevated temperature easily and air reaction, but the high melting point of 1668 DEG C. At room temperature, titanium is not afraid of aqua regia and dilute nitric acid corrosion resistance, but not more than 5% acid corrosion and 7% hydrochloric acid corrosion. Titanium is not afraid of ambient seawater, someone had put a piece of titanium sank to the bottom of the sea, five years later to take up a see, above the sticky many small animal and marine plants, but not a bit rusty, still shining. People began to use titanium to titanium submarines -- manufacture of submarine. Since titanium is very strong, can bear high pressure, the submarine can sail at a depth of 4500 meters deep in the sea.

Titanium is a very active metal elements

       Titanium is a very active metal elements, and can effect all the elements, titanium during heating, can interact and oxygen, the oxide film formed on the surface. At different heating temperatures, the structure and properties of the oxide film is different. Thermoforming titanium complex, each batch is different mechanical properties, in order to ensure the quality of materials, manufacturers are available certificate and test report.
       1. Preparation of titanium raw material supply state requirements
       A titanium plate deformation - in metallurgy factory rolled into sheets of poor performance repeatability. Domestic and foreign production of titanium same composition, mechanical properties of the difference is not small; domestic different sheet metal factory production, performance is not the same, even if a plant product, different furnace number of its mechanical properties are not the same. Therefore, in order to ensure the quality of the parts, you should first make sure that the quality of raw materials. Treasury requisitioned from titanium and titanium plate for aerospace sheet, should be equipped with the manufacturer factory certification and factory re-inspection certificate. In order to facilitate future verification, certification should be saved. When necessary, the basic situation of each plant can manufacture sheet metal parts to make records to future reference.
       All the plates were annealed condition require supply. To ensure the quality of the parts should be removed oxide and other pollutants plate surface. Titanium surface may not have cracks, peeling, crimping, inclusions and other defects, as well as through the traces of pickling. Sheet should be straight and wrapping paper out of the library. In the material after forming, assembly, transport and storage process, should be taken to prevent surface scratches.
       2, powdered metal suppliers rough cutting
       Wool preparation methods used in a variety of sheet metal parts, there are many similarities. Since the titanium plate thickness generally used in less than 2 mm, and a thickness of 1.5 mm or more parts so few titanium plate cutting can utilize existing equipment at room temperature.
       When cutting, should pay attention to try to make the edges smooth wool, particularly to prevent the edges of cracks, bite wounds and cut marks and other defects, in the cut planks should pay attention.
       Before forming wool deburring and removal should be sharp edges. Because of the sensitivity of titanium crack growth is strong, this work is extremely important, in order to eliminate the stress concentration to prevent cracking and scratches wool die during forming. Available cutting and filing, or sandpaper belt grinding deburring or polish.
       It should be noted that regardless of which method is used under the material, when crossed, only use non-polluting ink and pen, is not allowed to play in the wool stamp, offset or specially equipped only play tag.
       3, before forming degreasing and cleaning
       Before any thermoforming, should remove surface grease, or other contaminants, in order to avoid contamination of the titanium produced when heated. In addition, the surface of the oxide wool reduces plastic material, should be removed prior to forming. Therefore, in order to reduce the impact of various types of atmosphere environment, generally using a vacuum hardening furnace and vacuum annealing furnace heating, vacuum furnace inert gas can protect titanium and titanium alloy materials in the heating process from contamination.

Titanium can quickly react and gas

Liquid and solid titanium can not react, not combined with aqua regia could not reach it, however, titanium gas is very hit it off, like with nitrogen, oxygen, hydrogen, carbon dioxide, water vapor, methane and many other gases combined. This feature can produce titanium magical for us to use.
     You do not have more than one night to enjoy the colorful fireworks festival over it? Here there is a credit titanium. When combined with titanium powder and oxygen to burn quickly, and be able to produce a strong heat and glory. Fireworks can not only enhance the festive atmosphere at the festival, but also as a military flares, used to indicate the target or convey orders. In the arc lamp in the added amount of the grade 2 titanium forged ring compound, can increase its brightness. Using titanium strong absorption of air, the air can be removed, creating a vacuum. For example, the use of a vacuum pump made of powdered metal suppliers, you can put the air pumped only 1,000 million million. In the metallurgical industry, plus a small amount of titanium to steel or other metals, the "eat" inside the gas and impurities, can play a very good addition to the role of nitrogen deoxygenation, but also to eliminate the harmful effects of sulfur, thereby improving the steel and other alloy mechanical properties, to improve their resistance to corrosion.

Chemical properties of titanium

Titanium in high temperature, can react with many elements and compounds. A variety of elements, according to their different reactions occur with titanium can be divided into four categories:
The first category: halogen and oxygen group elements and Titanium round bar generating covalent bond and ionic bond compounds;
Class second: transition elements, hydrogen, beryllium, boron family, carbon group and pnictogens and Ti intermetallic compound and limited solid solution;
Third class: zirconium, hafnium, vanadium family, family, scandium and titanium produce infinite solid solution;
Fourth class: inert gas, alkali metal, alkaline earth metal, rare earth elements (except for SC, actinium, thorium and other external) no reaction or reaction does not occur basically and powdered metal suppliers.

The ultra high pure titanium

In 2014 September, the first furnace "China electronic grade hypoxia ultra high pure titanium" in Zhejiang city of Yuyao province successfully developed and put into production, the one to break the foreign monopoly. Hypoxia ultra high pure titanium bar stock is mainly used for sputtering target materials, aerospace, marine petroleum in the semiconductor core industrial areas, strategic significance. It is particularly worth mentioning is that the ultra high pure titanium is an important guarantee of raw materials of Chinese own large aircraft project. Prior to this, the ultra high pure titanium prices of imported from abroad for 1200000 yuan / ton, by purifying technology limited, three companies, only the United States and Japan all over the world to the production of ultra high purity titanium. As a high-end strategic metals, American and Japanese government restrictions on Chinese exports. China in the field of ultra high pure titanium is often to see Japan's "face". Means that China has own production capacity of hypoxia of ultra high purity Gr5 titanium forged ring, realizing independent self-sufficient this strategic metal, completely free themselves from dependence on foreign. To break the monopoly, direct benefit is the field of aerospace.

The historical development of titanium

From the discovery of titanium element to prepare pure, lasted for more than a hundred years. While the titanium has actually been spent, recognize the true face of the original, is in twentieth Century, after 40 years of things.
The surface of the earth ten kilometers thick stratum, titanium containing up to 6/1000, 61 times more than copper, the content in the crust (crust in the tenth row elements ranking: oxygen, silicon, aluminum, iron, calcium, sodium, potassium, magnesium and hydrogen, Titanium Flange Screw), literally from the ground up a handful of dirt, which contains a few thousandths of titanium, the world's reserves of more than ten million tons of titanium ore is not rare.
There are a million tons of sand on earth, titanium and zirconium these two than sandstone heavy mineral, is mixed in the sand, after the sea millions of years around the clock to washing, compare heavy ilmenite and zircon placer rushed together, in the long coastline, the formation of a piece of titanium ore layer and zirconium ore. The seam is a black sand, there are usually a few centimeters to tens of CM thick. Titanium tube fittings is not magnetic, titanium built nuclear submarines do not have to worry about magnetic mine attack.
