Breakthrough advantages of composite materials
1. Bimetallic composite structure | Perfect balance of conductivity and mechanical strength
Technical principle: The composite structure of copper matrix (high conductivity) + silver alloy coating (high corrosion resistance/wear resistance) combines the excellent conductivity of copper with the high temperature resistance and arc erosion resistance of silver alloy.
Quantitative advantages:
Conductivity ≥ 95% IACS (International Annealed Copper Standard), which is more cost-effective than pure silver contacts.
Coating thickness is adjustable from 0.1 to 0.5 mm to meet different current load requirements (such as 10A to 500A).
Tensile strength ≥ 200MPa, mechanical life of more than 100,000 times (IEC 60512 standard test).
2. Arc erosion resistance | Extend contact life and reduce maintenance costs
Technical highlights: Silver alloy coatings (such as AgSnO₂, AgCdO) have high melting points and self-lubricating properties, which can effectively resist arc erosion and reduce Three-Compound Contact surface wear.
Quantitative advantages:
Under AC 220V/10A conditions, the arc erosion rate is ≤0.02mm/10,000 times (industry average ≥0.05mm).
Life test reaches 500,000 times of switching, which is more than 3 times higher than traditional pure copper contacts.
Applicable to equipment with frequent start and stop (such as elevators, inverters), and the maintenance cycle is extended by 50%.
3. Wide temperature range stability | Adapt to extreme environment applications
Material properties: Both the copper substrate and the silver alloy coating have passed the -40℃~+125℃ temperature cycle test, without the risk of embrittlement or deformation.
Quantitative advantages:
Trimetal Moving Contact resistance fluctuation under high temperature conditions (+125℃) ≤±5% (industry average ≥±10%).
In a low temperature (-40℃) environment, it still maintains more than 85% of the initial conductivity.
