● Excellent conductive stability: Silver contacts have excellent conductive stability and can maintain their conductive properties for a long time. It is less susceptible to oxidation, corrosion and arc erosion, maintains stable electrical contact, and reduces heat generated during current transmission.
● High temperature resistance: Silver contacts can maintain stable performance in high temperature environments and have strong resistance to melting and ablation. This makes silver contacts suitable for electrical equipment operating at high temperatures, such as welding equipment, high-power motors, and other high-load equipment.
● Good corrosion resistance: Silver contacts have high corrosion resistance and can maintain good performance in humid environments or in the presence of corrosive gases. This makes silver contacts widely used in environments such as outdoor equipment, marine equipment and chemical industry equipment. It is worth noting that silver contact materials are more expensive than other materials.
Ag-Ni Series (Silver Nickel)
Details
Ag-Ni alloy has excellent electrical conductivity: Since silver (Ag) has extremely high electrical conductivity and nickel (Ni) has higher electrical conductivity, Ag-Ni alloy has excellent electrical conductivity. It can maintain good electrical conductivity under high current and high temperature, and is suitable for conductive connections in various electronic components and electrical equipment. Ag-Ni alloy has good wear resistance and corrosion resistance: nickel has high hardness and corrosion resistance, while silver has good wear resistance. By alloying the two, the Ag-Ni alloy can maintain its wear resistance and corrosion resistance for a long time in harsh environments, such as being used in environments with high temperature, high humidity or corrosive media.

Ag-ZnO Series（Silver Zinc Oxide）
Details
AgZnO alloy is a common contact material consisting of silver (Ag) and zinc oxide (ZnO). Contacts are the key elements used in electrical switches or relays, where current flows to close or open the switch. AgZnO material is widely used in high-load, high-frequency and long-life switchgear because of its excellent electrical properties and wear resistance. The combination of AgZnO makes it have the advantages of both silver and zinc oxide, and has the following characteristics: Excellent electrical conductivity: Silver is a good electrical conductor with low resistance and good current conduction performance, which can effectively reduce resistance loss. The silver particles in the AgZnO material provide an excellent conductive path, enabling the contacts to operate stably under high load conditions. Good wear resistance: Zinc oxide has high hardness and wear resistance, which can effectively resist the wear caused by contact and separation of contacts. The AgZnO material exhibits good durability under frequent switching and high-voltage arc conditions. Oxidation resistance: The zinc oxide layer can form a protective film on the surface of the contact, which can effectively prevent the direct contact between the contact and the external oxygen, thereby slowing down the oxidation speed of silver. This resistance to oxidation prolongs the life of the contacts. Lower arc and spark generation: AgZnO material can effectively suppress the generation of arc and spark, reduce signal interference and loss. This is very important for high frequency and high precision applications. Overall, AgZnO has good electrical conductivity, wear resistance, oxidation resistance, and arc suppression as a contact material, making it widely used in various electrical switch and relay applications.
