钨铜材料是钨和铜的一种合金，综合了钨和铜的优点，耐高温、耐电弧烧蚀、强度高、比重大、导电、导热性好，易于切削加工，并具有发汗冷却特性，作为真空触头材料、电极材料、电子封装材料以及火箭、导弹特殊用途材料等广泛应用于机械、电力、电子、冶金、航空航天等工业。
我公司采用等静压成型－高温烧结钨骨架－渗铜工艺，生产含铜量为6-90%的各种大型、异形件。产品纯度高，组织均匀，性能优异；采用模压成形、注射成形可生产各种片材、杆材、管材、板材和形状复杂的小型制品
Tungsten –Copper alloy is the composite of Tungsten and Copper which own the excellent performances of Tungsten and Copper, such as heat-resistant, ablate-resistant, high-intensity,high-density, excellent thermal and electrical conductivity. It is easy to be machined. It is used widely in such industries as engine, electric power, electron, metallurgy, spaceflight and avigation.Using CIP formation, sintered tungsten skeleton and infiltrating copper (silver) technology, large size and special shape products of tungsten-copper (silver) composites with 6-90 percent of copper are produced, such as electric contacts, electrode, refractory parts, heat sinks and parts of rocket. We can also produce sheet material, tubing, plate and other small products by mould pressing and MIM.
