Advantage
The key feature of the clad strip lies in its ability to organically combine the unique electrical and chemical properties of precious metals (gold, silver, platinum, palladium, iridium, rhodium, ruthenium, osmium) with the excellent mechanical properties of materials such as copper alloys. This results in superior comprehensive performance—offering stronger bonding than electroplating, with no delamination and secure adhesion—while significantly conserving precious metals.
By integrating multiple materials, the clad strip overcomes the limitations of individual components and leverages the respective strengths of each constituent. This yields excellent overall properties, including high bonding strength, good electrical and thermal conductivity, corrosion resistance, vibration damping, wear resistance, as well as specific specialized functionalities. The manufacturing process is simplified by eliminating traditional riveting or welding steps. It also features low temperature rise, superior performance, and enables integrated structural design.
After stamping into composite contacts, the welding surface is made of materials such as Monel, CuNi, Ni, or Fe, and includes pre-formed welding points to enhance joint strength. The welding process involves molten metal bonding, with short heating times, a clean working environment, precise positioning, and aesthetically pleasing results. An intermediate transition layer of copper is used to ensure low contact resistance and stable electrical performance.
