Detailed Specifications
Dimensional Accuracy Control
Silver Tin Oxide Contact dimensions have a tolerance of ±0.02mm, disc contact surface roughness Ra≤0.2μm, and convex contact height accuracy ±0.01mm. All contacts undergo full inspection using precision testing equipment to ensure assembly compatibility.
01
Weld Quality
Resistance welding and high-frequency welding welds are smooth and burr-free, with a porosity <0.5%. Silver brazing welds are full and dense, with a stable tensile strength ≥200MPa and no oxidation discoloration for Welding Button Contact.
02
Material Uniformity
The internal AgSnO2 Based Contacts undergoes nanoscale composite treatment, resulting in no component segregation and a uniform surface color. Metallographic analysis verifies the dense crystal structure, ensuring stable conductivity and arc resistance.
03
Terminal Adaptation
The integrated component's red copper/brass terminals are firmly welded to the silver contacts. The terminal dimensions are precise, allowing for direct equipment assembly without secondary processing.
04
Material Innovation
| Inner Oxide Silver Alloy | Through a unique high-temperature oxidation process, the Silver Contact Welding matrix and CdO/SnO2 are uniformly composited at the nanoscale. This innovative process increases the crystal density by 30%, achieves an electrical conductivity ≥42MS/m, and a hardness HV of 80-100, significantly superior to traditional powder metallurgy products. |
| Arc Erosion Resistance | AgSnO2(12) (AgSnO2 Based Contacts) exhibits excellent performance under high current conditions. In current environments above 20A, the arc burn-out rate is reduced by 50%, and the contact resistance remains stable below 0.5mΩ, effectively ensuring the stability and reliability of the Welding Button Contact under long-term high-current operation. |
Finished Product Performance Testing
Welding Strength Test
Verified through shear tests, the AgSnO2 Based Contacts joints is no less than 50N, and that of silver-bonded joints is no less than 120N.
Interface Integrity Inspection
The Silver Tin Oxide Contact is inspected using X-ray non-destructive testing to ensure that the porosity is less than 0.5%.
Electrical Performance Verification
Welding Button Contact is measured by sampling, and electrical life and arc resistance tests can be performed under simulated operating conditions.
