Continue Reading →Speaking of metal pipe, a lot of people will think of titanium pipe. Indeed, titanium tube in our daily life, the application is very extensive. However, many people do not know much about titanium tubes.
Continue Reading →The target material is a material used as a cathode in sputtering deposition technology, which can be separated from the cathode in the form of molecules, atoms or ions and redeposited on the surface of the anode under the impact of positively charged cations.
Continue Reading →The tungsten wire can be used as the core in the cavity of the melting model, and the liquid metal can be poured into it to wrap it, similar to the structure of steel and concrete, which does not affect the casting fluidity, but also can increase the high-temperature strength of the blade turbine, because the large amount of tungsten can reduce the cost.
Continue Reading →Platinum is one of the world's rarest metals used in jewelry. Only a few places in the world, such as South Africa and Russia, produce just 5% of gold a year. Tons of ore, more than 150 processes that take months to extract, produce enough platinum to make a simple ring weighing a few grams.
Continue Reading →The material can cost ten or even tens of times as much as pure titanium. It's also a class of titanium alloys, but it's super elastic, and it's shape memory. We once made a toy out of memory titanium, which was a lotus flower.
Continue Reading →1, large chemical activity, easy oxidation. Zirconium alloy is easy to form an oxide layer in the air, and the strength and hardness of the oxide surface layer are higher, so the grinding force per unit area is larger.
Continue Reading →The most important use of niobium is the manufacture of various niobium alloys and as an additive in steel. Among all kinds of microalloying elements in steel, niobium is the most effective microalloying element.
Continue Reading →The element vanadium exists in solid state in titanomagnetite. After the first stage of treatment, the magnetite concentrate enters the traditional baking leaching precipitation process for vanadium recovery.
Continue Reading →Maybe you do not know the chromium zirconium copper tube, in fact, the utilization rate of chromium zirconium copper tube is very high now, in our home a lot of electrical appliances are used, like air conditioning ah, refrigerator ah, and some other.
Continue Reading →Graphite heat exchanger is a widely used heat exchange equipment in industry. It is mainly used for heat exchange of corrosive media such as sulfuric acid, hydrochloric acid, acetic acid and phosphoric acid.
Continue Reading →Platinum crucible is mainly refined from high purity platinum. Now because some factories, pharmaceutical factories, scientific research institutions need related scientific experiments. These experiments may involve highly corrosive chemicals or require forging at high temperatures.
Continue Reading →Due to the great defects of titanium itself, titanium alloy has broken through the "thermal barrier" of 600 degrees, and the service temperature has reached a higher level. It is still very difficult to replace nickel-based superalloy, and better new materials and new processes are needed.
Continue Reading →There are two ways to make tungsten-rhenium alloy: powder metallurgy and smelting, and powder metallurgy is commonly used in actual production. The powder metallurgy process for producing tungsten-rhenium alloys is as follows:
Continue Reading →Tantalum forms a stable anodic oxidation film in acidic electrolyte. Electrolytic capacitors made of tantalum have the advantages of large capacity, small volume and good reliability. The production of capacitors is the most important application of tantalum……
Continue Reading →High strength and toughness light zirconium alloy can be divided into crystalline zirconium alloy and amorphous zirconium alloy.
Crystalline zirconium alloy can be divided into α type zirconium alloy, α+β type zirconium alloy and β type zirconium alloy according to its phase composition.
The main strengthening ways of niobium are solid solution, precipitation and deformation heat treatment. In Nb alloy, the high and low temperature strength of Nb alloy can be significantly improved by containing tungsten and molybdenum, but too much will reduce the technological properties of Nb alloy.
Continue Reading →The thermal conductivity of titanium alloy is very poor, and the contact length of the chip and the tool is very short, which is not conducive to the export of cutting heat, so that the temperature of the cutting edge area is high, about twice as high as that of the cutting 45 steel.
Continue Reading →Platinum-iridium alloy is a binary platinum-based alloy containing iridium. It is a continuous solid solution at high temperature and decompose in solid phase at 975 ~ 700℃ after slow cooling, but the phase equilibrium process is very slow.
