COPPER HEATSINK

Copper is highly regarded for its exceptional thermal conductivity, making it a material of choice for heat dissipation. Compared to other heatsink materials, such as aluminum, copper has a significantly higher thermal conductivity, allowing for better heat transfer and dissipation. This means copper heatsinks are ideal for electronic devices in preventing overheating.

At Radian Thermal Products, we understand the importance of high-quality materials in manufacturing. That is why we specialize in manufacturing and supplying copper heatsinks. These heatsinks are designed to withstand demanding environments and provide reliable heat management for various electronic applications.

Copper is an excellent conductor of heat and Radian uses Cu1100 which has a thermal conductivity of ~ 380W/m-K. Despite the excellent thermal properties of a copper heatsinks, aluminum heatsinks are typically used as they weigh approximately half as much as a copper conductor having the same conductivity, and are also less expensive. Although it is possible to machine a copper heatsink this can be fairly inefficient as the tools blunt fairly quickly. Typical manufacturing is by either the forged or skiving process that allow the copper heatsink to made from a single block. Another manufacturing process that is used especially with vapor chambers is the use of stamped copper fins that are soldered or epoxied onto the base. Many of our customers also add an anti-oxidation coating, or nickel plate to maintain the look of the copper heatsinks as they can tarnish over time.
