What material makes the shielding cover more effective [hardware]

The shielding cover is a kind of metal shielding cover used in the current electronics and communication industries to shield electromagnetic wave signal interference. So which material can be selected for the customized shielding cover to have a better shielding effect? Xiaoshuo will take you to understand: 1. So far, many businesses still use tinplate material, which is an iron material with a tinned surface, which can be tinned and has a shielding effect. But it is easy to rust. 2. Zinc-tin-nickel alloy, a material originating from Japan, that is, in the essence of iron, an electroplated layer of zinc, tin, and nickel is added. It can be tinned, and it also has a shielding effect. But the essence is still iron, and there is also the problem of rust. 3. Foreign white copper, so far, uses a relatively large amount of raw material. The shielding effect is good, and the tinning performance is good. Many customers use this material when designing. 4. Of course, there are some other materials, such as: some companies use red copper and brass, which are used as shields since electroplating, and some aerospace fields use aluminum for shielding. Hardware, 15 years of ingenuity and focus on shielding, 20,000+ sets of mold custom processing and production experience, monthly 100+ sets of mold processing capacity, daily production capacity of 3 million punches, stamping accuracy up to 0.01mm, 16 quality inspections strictly It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve mass production quality problems. Choose, choose to rest assured!
