Riveting copper sheets are particularly common in the architectural, decorative, electrical and craft manufacturing sectors. Here are a few of the main reasons for riveting copper sheets:

• Avoiding thermal effects (compared to soldering): The extremely high thermal conductivity of copper (approx. 401 W/m-K) makes it extremely easy for heat to diffuse when soldering or brazing. This may therefore lead to localized overheating, annealing, and discoloration of the part; difficult control of the weld; and damage to adjacent parts (especially in precision copper parts). Riveting, on the other hand, is a cold joining process that avoids heat affected zone (HAZ) problems.
• Easy on-site operation and maintenance: riveting can be implemented in the environment without electricity and gas source (e.g., construction of building roofs and facades); lower technical dependence on the construction personnel and higher safety compared to welding.
• Compatible with the performance of copper itself: copper is easy to oxidize, not resistant to high temperature impact, welding spot easy discoloration; riveted joints do not destroy the surface integrity, can maintain the original texture of copper or treatment layer; the use of copper rivets rivets, can avoid galvanic corrosion (especially on aluminum or iron material easy to cause corrosive damage).
• Traditional craftsmanship and aesthetics: in architectural copper trim (e.g. church roofs, copper rain gutters), riveting meets the aesthetics of traditional coppersmith craftsmanship.
• Safer in certain electrical situations: Copper is often used as a conductor in electrical engineering, and soldering can change the conductivity due to overheating. Riveting can provide mechanical fixing support without affecting the conductivity; for example, in high frequency applications, electromagnetic interference can occur at the soldering point, whereas mechanical connections are relatively stable.
