Which material to choose for the shielding cover has the better shielding effect? u200bu200b+ The raw materials are imported and the national standard original factory

The shielding cover is a kind of metal shielding cover used by the electronics and communication industries to shield the signal interference of electromagnetic waves. So which material can be selected for the customized shielding cover to have a better shielding effect? The following Xiaoshuo will take you to understand: 1. Tinplate material, which is an iron material with a tin-plated 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 nature 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 is one of the most used raw materials so far. The shielding effect is good, and the tinning performance is good. Many customers use this material when designing. Of course, there are other materials, such as red copper and brass, which are electroplated to be used as shielding covers, and some aerospace fields use aluminum for shielding. Hardware, 15 years of focus on shielding design and production, 20,000+ sets of mold custom processing and production experience, monthly 100+ sets of mold processing capacity, 3 million punching production capacity per day, stamping accuracy up to 0.01mm, and 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!
