Grade: YLH90 density :13.2-13 .5 flexural strength: 258 Hardness: 81.5 Usage: forging mold for the production of impact resistance. Carbide combines the advantages of tungsten and copper, high temperature resistance, arc erosion, high strength, heavy, electrical conductivity, thermal conductivity, easy machining, and has features such as transpiration cooling, because having a tungsten high hardness, high melting point, anti-adhesion characteristics, are often used to make a certain wear resistance, high temperature welding, welding electrode. Four high-pressure discharge electrode: high-voltage vacuum discharge tube at work, the contact material in the fraction of a second of time temperatures thousands of degrees Celsius. The tungsten and copper ablation resistance, high toughness, good electrical conductivity, thermal conductivity to provide the necessary stable discharge conditions. ● Electronic Packaging Material: Tungsten, low expansion characteristics, but also has a high thermal conductivity of copper, the thermal expansion coefficient and thermal conductivity of the material can be adjusted to change the composition and thus to provide a convenient use of materials.
