What is Tungsten? Tungsten is a hard, dense, metallic element with the chemical symbol W and atomic number 74. It has the highest melting point of all metals and is used in various applications such as filaments for incandescent light bulbs, electrical contacts, and alloys for tools and equipment that require high strength and durability. Tungsten is also used in the production of X-ray tubes and radiation shielding. It is often referred to as a "heavy metal" due to its high density and weight.Tungsten Heavy Alloys Blank Application of tungsten heavy alloy cylinders 1. Manufacturing high temperature equipment: tungsten alloy cylinder has the characteristics of high melting point, high hardness, high density, so it is often used in the manufacture of high temperature equipment, such as high temperature furnace, vacuum furnace, high temperature heater, etc. 2. Manufacturing electronic components: tungsten alloy cylinder has good conductivity and corrosion r…
