Based on a series of events in the tungsten industry throughout the year, the Tungsten and Molybdenum Merchant sorted out the top ten hot news of the tungsten industry in 2019.
Molybdenum electrode is a molybdenum electrode material, using its unique advantages, temperature, continuous surface, good conductivity and stable edges, excellent corrosion resistance-to improve its overall quality and age of use.
Opening this week, the tungsten price in China remained weak adjustment as traders were active in selling products, but buyers still took a watchful stance. The whole market is quiet with rare transactions concluded.
Tungsten alloy weight has high density, high melting point, high hardness, high wear resistance, high ultimate tensile strength, high elongation, good machinability, non-toxic and pollution-free, high impact resistance and crack resistance
Tungsten alloys are widely used as shields in industry, nuclear energy, and medical fields. Due to its high density and large atomic number, tungsten alloy is the best material for shielding, which can shield gamma rays and X-rays.
Different castings have different casting methods. Sand casting is commonly used, followed by special casting methods, such as: metal casting, investment casting, gypsum casting, etc.
Cemented carbide forging die is also called forging die. It has good heat resistance and fatigue resistance. It applies a certain pressing force through the closing and closing of the upper and lower dies, so that the forgings have better structure and mechanical properties.
The investment casting process is to use a fusible material to make a fusible model, apply several layers of special refractory coatings on it, dry and harden to form an integral shell, and then use steam or hot water to melt from the shell.
