Housing

The material of housing is 303 stainless steel polished and passivated. The process of passivated stainless steel is to prevent corrosion, it leads to a protective oxide layer that is less likely to chemically react with air and cause corrosion. It allows screw-in and screw-out smoothly and remains a shiny appearance for a long time.

Center Contact

The material of center contact is beryllium copper with two layers of plates. It first comes with a layer of nickel, and then comes with a layer of gold. Gold plating is often used in connectors, to provide a corrosion-resistant electrically conductive layer, both nickel and gold are plated to reduce the losses at high frequencies due to higher electrical resistance. The center conductive part of our connector, glass bead, round pin, flat pin, are nickel-plated first and then gold-plated.
