Silver Alloys - AGCDO
Introduction to Alloys:
Silver alloys exhibit unparalleled electrical and thermal conductivity, significant resistance to bending, strong adherence to welding, low contact resistance, exceptional toughness, and endurance compared to other metals, thereby minimizing damage in both manufacturing and braking processes. Coupled with chemical stability, their excellent thermal and electrical conductivities make silver highly effective in electronic devices. Due to these outstanding functional characteristics and high corrosion resistance, silver alloys are considered ideal materials for electrical contacts in various low-voltage systems and electronic devices over many years.
Tin Oxide:
Recent research has centered on silver tin oxide (AgSnO2) materials, many of which are currently employed in a variety of applications. Research has been conducted to assess the electrical and mechanical efficiency of these materials, particularly due to concerns over the decay and vaporization of CdO under flame action, which also exhibits some level of toxicity.
Noble Technology offers Silver Cadmium Oxide Contacts made using advanced techniques like internal oxidation and powder metallurgy, tailored to meet specific customer needs.
These contacts, made of AgCdO, boast impressive qualities such as resistance to welding and spark corrosion, low contact material resistance, excellent electrical and thermal conductivity, resistance to arcing, strong adherence strength, minimal contact resistance, and high durability. As a result, they are the preferred choice for electrical contacts in various low-voltage instruments used by contractors for many years.
