Copper Rivets For Metal
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.1mm
Copper rivets for metal is a classic and reliable solution for metal joining. It has excellent electrical conductivity, and its electrical conductivity can reach more than 85% of pure copper standards. This makes it ideal for electrical grounding and cooling components. At the same time, copper alloys are naturally resistant to corrosion. In standard salt spray testing, high-quality copper rivets remain free of underlying red rust for more than seventy-two hours. This ensures long-term stability of the connection point in humid and harsh environments.It performs equally well in terms of installation and durability.
This rivet performs equally reliably over long periods of use. It forms a permanent connection that is highly resistant to vibration, withstanding more than 10 million vibration cycles without loosening in laboratory testing. The electrochemical potential difference between it and common metals is very small, and the corrosion current density is usually less than 0.5 microamps per square centimeter, which can effectively reduce the risk of electrochemical corrosion when connecting dissimilar metals.
Drawing Design & Confirm
Obtain drawings from customers or create drawings based on their specifications or samples.
The drawings, product raw materials, surface treatment, and other details are attested to by both parties.
Benefits
Excellent Thermal Conductivity
Copper is an excellent conductor. Its conductivity can reach over 85% of that of pure copper. In electrical connections, it can stably transmit current.
In heat dissipation structures, it can efficiently dissipate heat. This makes it an ideal choice for grounding and heat dissipation components, significantly improving equipment reliability.
Ease of Machining
High-quality copper rivets have excellent ductility. The elongation at break can reach over 15%. During riveting, the rivet shank deforms uniformly, forming a full and strong rivet head. The entire process is less prone to cracking.
It supports cold riveting with manual or pneumatic tools. No heating is required, resulting in high efficiency and consistent quality.
Low Corrosion Risk
Copper has a small potential difference with common metals. For example, the corrosion current density with steel is typically below 0.5 µA/cm². This greatly slows down contact corrosion.
Therefore, it is safer when connecting aluminum or stainless steel, effectively protecting the base material. It is particularly suitable for harsh environments such as marine and aerospace applications.
Excellent Magnetic Permeability
Copper rivets are non-ferromagnetic. Their relative magnetic permeability is very close to 1. No stray magnetic field is generated during use. This ensures the purity of signals from precision instruments.
It is essential for sensitive environments such as MRI equipment and navigation systems. Ordinary steel fasteners cannot compare.
