Since the EU's exemption for cadmium oxide, a non-environmental material, is due to expire in 2021, it needs to be replaced.We use environmental protection material tin, through the powder mixing process, prepared silver tin oxide material, which can be well replaced, in various relay manufacturers have been successfully tested
Compared with the processing cost of silver cadmium oxide materials, the technological process of silver tin oxide is basically the same, so there is basically no increase in cost
In terms of physical performance indexes, the hardness of silver tin oxide is higher than that of silver cadmium oxide, so for rivet type contact, there will be higher requirements on the mold
If you have any need, please contact us. We can provide samples for testing for free
