Overview

NEWLIFE High Power Heat Sinks are engineered for extreme thermal management in high-power laser systems, including industrial, medical, and defense applications. Utilizing tungsten–copper (W–Cu) alloys and high-conductivity copper, these heat sinks offer rapid heat spreading, low thermal distortion, and structural stability under continuous-wave (CW) or pulsed laser operation.

Manufactured via Powder Metallurgy (PM) and sintering-infiltration technologies, NEWLIFE heat sinks achieve high density, uniform microstructure, and precise dimensional control, which are challenging to obtain using traditional machining, extrusion, or casting methods. PM enables near-net-shape production of finned plates, micro-channels, and cavity structures, reducing material waste and post-processing while allowing complex geometries for optimized thermal flow. NEWLIFE's proprietary powders provide predictable thermal expansion, mechanical strength, and consistent thermal conductivity across large or intricate components.

These heat sinks ensure stable optical alignment, reduce hotspots, and maintain long-term reliability even under high thermal loads. Compared with conventional machined copper, W–Cu PM components maintain lower deformation, higher density, and better thermal conductivity, especially in high-power laser environments.
