Embodiment 1
[0022] The highly conductive silver-based melt material of the present invention is formed by melting 92 kg of silver, 12 kg of silver-based graphene, 0.2 kg of rubidium, and 0.3 kg of indium:
[0023] First, 12 kg of silver-based graphene and 34.5 kg of silver were smelted into alloy material A1 in a vacuum smelting furnace; then 0.2 kg of rubidium, 0.3 kg of indium and the remaining 57.5 kg of silver were smelted into alloy material A2; finally, the melted alloy The material A1 is added to the molten alloy material A2 to obtain a molten silver-based alloy, and the molten silver-based alloy is cast or horizontally continuous casted, extruded, and drawn to obtain a highly conductive filamentous silver-based melt alloy, The melt alloy has high electrical conductivity (it is stronger than that of pure silver, and when pure silver is 20°C, the resistivity is the lowest 15.62×10 -6 Ω mm), moderate melting temperature and excellent mechanical properties, its technical indicators a...
Embodiment 2
[0025] The highly conductive silver-based melt material of the present invention is formed by melting 101 kg of silver, 2 kg of silver-based graphene, 0.3 kg of rubidium, and 0.2 kg of yttrium:
[0026] First, 2 kg of silver-based graphene and 37.8 kg of silver were smelted into alloy material A1 in a vacuum smelting furnace; then 0.3 kg of rubidium, 0.2 kg of yttrium and the remaining 63.2 kg of silver were smelted into alloy material A2; finally, the molten alloy Material A1 is added to the molten alloy material A2 to obtain a molten silver-based alloy, and the molten silver-based alloy is cast into an ingot, and the ingot is first extruded into a strip, and after rough rolling and finish rolling, a high conductivity A strip-shaped silver-based melt alloy with high electrical conductivity (stronger than that of pure silver. When pure silver is at 20°C, the resistivity is the lowest 15.62×10 -6 Ω mm), moderate melting temperature and excellent mechanical properties, its tech...
