There are main three grade materials used in corona shielding rings and shielding parts production, this article will have a brief introduction about these materials.
It is a popular material to use for corona shielding rings and parts production because it is both cost effective and high weather resistance. The soft hardness is easily processing and polishing. Since aluminum material is high strength with light weight, our partners can benefit from the material because the corona products made of these are high purity and light for transportation and easily installed.
Copper alloys offer 99.80% IACS high electric conductivity and high precision appearance, making them a popular choice for custom made of electrical conductors and shield copper balls. The copper spheres are widely used in power frequency withstand voltage test.
Stainless steel is the kind of material which is not easy rust, acid resistance and corrosion resistance, so it is widely used in light industry and heavy industry. Sometimes end users need some special corona rings made of stainless steel for outdoor application.
