一、铝导电氧化的特点 铝的比重为2.7克/厘米~3,约为铜的1/3,应用铝合金取代铜合金制作微波器件,可以大大减轻设备的重量,因而长期以来得到了人们的关注。 在国外采用经导电氧化处理的铝合金取代经表面镀金或镀银的铜合金来制作波导元 First, the characteristics of aluminum conductive oxide The proportion of aluminum is 2.7 g / cm ~ 3, about 1/3 of copper, the use of aluminum instead of copper alloy production of microwave devices, can greatly reduce the weight of the device, which has long been people’s attention. Conducted in foreign countries by the oxidation of the aluminum instead of by the surface of gold-plated or silver-plated copper alloy waveguide elements
