Process introduction
The production process of silver cadmium oxide is generally internal oxidation smelting.
The production process includes pre oxidation sintering extrusion and internal oxidation.
In this process, the silver plate and cadmium ingots are melted at high temperature and poured into a cylinder to form the silver cadmium alloy, which is then oxidized in the oxygen environment through the oxidation furnace to form the silver cadmium oxide
Cadmium oxide content is about 10-20% by weight.
Performance introduction
This material is called universal material, because in the process of contact, the contact surface heating, will produce resistance to fusion welding of cadmium vapor, so it in the ac test conditions, the ability to resist adhesion is relatively strong.
The preparation process of the wire is relatively long, so the production cycle generally takes 7 to 10 days, and the size of the wire can range from 0.8mm to 4mm
Application area
Silver cadmium oxide is the most widely used contact material for low voltage electrical appliances. It has good resistance to arc burnout and fusion resistance and low contact resistance from start to finish during use. However, cadmium and cadmium oxide are not good for health and the environment, and silver cadmium oxide materials are banned in some countries.
Mainly used in various low voltage switchgear. Such as micro switches, relays, lighting switches, contactors, household appliances switches, various protection switches and some circuit breakers.
