The Ministry of Natural Resources, Ministry of Industry and Information Technology has jointly issued the “Circular on the Total Control of Tungsten Ore Mining in the 2018 Year (First Batch)” (hereinafter referred to as the “Notice”), proposing to protect and rationally develop advantageous minerals
Superalloys are widely used in aviation, aerospace, warships, power generation, power, locomotives, and petroleum and chemical industries as key components of materials due to their unique mechanical and physical properties.
In the past five years, the contribution rate of China's scientific and technological progress to GDP has increased from 52.2% in 2012 to 57.5%, and the global ranking of national innovation capacity has risen from 20th to 17th. Mechanisms, talents, and finances, like finely-woven neural networks an
In a variety of sintering technology, microwave heating with heating speed, the overall heating, selective heating and non-thermal effects and other traditional heat conduction heating mode does not have the characteristics. Carbide (WC-Co) powder compact has a good coupling absorption effect on mic
Carbide floating reamers can float in the axial direction or along the vertical space swing or both with these movements to effectively compensate for machine tool thermal deformation, workpiece mounting, reamer, etc. in the horizontal axis or vertical space error.
Pure tungsten and molybdenum products as sapphire growth furnace is an important material. Tungsten Molybdenum products for sapphire crystal furnace are mainly made of tungsten raw materials and molybdenum raw materials with purity over 99.95%, including tungsten crucible, tungsten plate, tungsten p
The tungsten copper powder sintered material is distributed in the form of tungsten as the skeleton evenly on the copper matrix. Due to the high melting point and high hardness of tungsten W, tungsten at 1000 ℃, its ultimate tensile strength is still 50kgf / mm2, higher than the strength of low-carb
Carbide forging is also known as forging die, with good heat resistance and anti-fatigue ability, which through the upper and lower mold clamping to exert a certain squeeze force, making die forging better mechanical and mechanical properties. There are many types of carbide forging die, mainly clas
