AgCdO15 Silver Contact Tips for AC Contactor
1. Product: AgCdO15 Silver Cadmium Oxide Contact Tips with good arc erosion widely used in almost every type of low voltage switching devices
2. Materials: AgCdO10, AgCdO12, AgCdO13, AgCdO15, AgCdO17, etc.
3. General description
AgCdo(Silver Cadmium Oxide) contact belongs to the group of the most widely used ones in the field of low voltage electric apparatus. They combine a satisfactory resistance against contact welding with a good arc erosion resistance and a fairly low contact resistance over its complete service life. They are produced with two different techniques, pre-oxidation-sintering-extruding, and internal oxidation. In both cases, CdO content may range from 10 to 20wt%. However, Cd and CdO are considered to be hazardous to health and the environment. For this reason, the use of AgCdO materials will be banned in a number of countries.
4. Application Scope
Mainly used in almost every type of low Voltage switching device. They are typically used in microswitches, relays, light switches, contactors, switches for household appliances, some types of protective switches, as well as in certain types of circuit breakers.

6. Relevant series’ Applications
AgW, CuW, AgWC contacts choose different powder materials by adding inside Ni, Co mineral and by using pre-sinter and active sinter technology then improve their consistency and ameliorate the electrical function of contact materials. Mainly used in middle and large capacity relay, contactor, middle and small capacity low voltage breaker, DC/AC switch, drive protective switch, creepage protective switch, etc.
Their applications are as follows:
A) AgW series
All kinds of omnipotence breakers, plastic breakers, heavy charge AC/DC contact or other switches.
B) CuW series
Widely used in high voltage breakers.
C) AgWC/AgWCC series
Mainly used in high electricity charge switchgear such as a breaker, and creepage switch. Generally, they are used with AgNi , AgWC together.
D) AgNi series
Widely used in DC/AC relay, designation switch, contactor, light switch, thermal controller, timer of washer, etc.
E) AgNiC series
Widely used in omnipotence breakers such as DW45 intelligence coupling with AgW.
F) AgC series
Mainly used in protective switches such as a miniature breaker, creepage protective switch, or motor protective switch with coupling contact in AgW.
G) Silver oxidized metal series
Mainly used in relay, contactor, small and medium-sized capacity and DC low voltage circuit breaker switch powder protection switch and leakage protection switch, etc.

2. Can you help us to choose suitable contact material?
We can recommend the most suitable contact material to customers according to the electrical contacts application, based on a rich fund of knowledge of kinds of contact material.
3. What kind of electrical contact material you can provide?
We can provide Pure Ag ,AgSnO2 , AgSnO2ln2O3 , AgCdO , AgCuO10 , AgZnO , AgNi , AgCe , AgC , AgWC , AgW , CuW Etc. contact material.
4. Can you provide samples for the test?
As Wenzhou Longsun Electrical Alloy Co., Ltd. has manufactured electrical contacts for many years, so they have many different types in stock, if the electrical contact you need is similar to the size in stock, they can send them to you within one day, if you can not use the similar size, they can make samples and send them within 10-15 days.
5. Can you make some special electrical contacts such as a special shape or use special contact material?
We can provide some electrical contacts made with special materials, such as CCW contact material, AgWC contact material, AgW contact material, AgCu contact material, CuAg, contact material, AuAgCu contact material, AgCuNi contact material…
We also provide special shape electrical contacts according to customers’ design.
6. How do you control quality? Can you give a simple description?
we provide tri-metal Silver Electrical Contacts samples to customers for checking before production; we will not produce until the sample is approved; we will do the product inspection randomly in the process of production to detect the problem in time, we also will select random products for customers to checking according to customers’ requirements after the completion of the production before shipping.
For the products with high assembly requirements, we will ask customers to provide the assembly parts, to ensure that the products can be assembled ok before shipment.
7. Can you report during production?
During production, we mainly Provide valuable pictures or videos to our customers, we provide clear pictures of silver tri-metal contact rivets samples to customers for checking before the shipment; provide pictures of products and cross-section inspection report which is in the process of production; provide detailed packaging pictures showing the quantity and packaging of each product clearly after the completion of production.
8. How do you arrange freight?
For samples, we usually use Courier, such as UPS, FedEx, DHL, TNT, and EMS. If gross weight is below 100kg, we usually deliver them by air, for 100kg or above, we usually deliver by ship. If our customer is in urgent needs to get the goods, we can arrange to send them by air.
