Grade: YLH100 density :13.0-13.4 Flexural strength: 1650 Hardness: 81 Use: production of dies, red top wear parts with high strength and impact resistance. High voltage 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.
