Cold Forged Heat Sink And LED Lighting Heat Dissipation Assembly
Product Advantages of Cold Forged Heat Sinks
Manufactured from T1/T2 pure copper with the cold forging process, it features a thermal conductivity of up to 390W/m·K.
It achieves an optimal balance among thermal performance, reliability, cost, weight and dimensions.
Compared with traditional processes, its thermal resistance is reduced by 40%.
Advantages of Cold Forging: No black scale remains at the root of the pillars after CNC machining.
Disadvantages of Hot Forging: Large areas of black scale are left at the root of the pillars after CNC machining.
