Key Features
High Thermal Efficiency
Copper's inherent thermal conductivity allows rapid heat transfer away from sensitive components such as laser chips and photodiodes. This significantly reduces thermal resistance and ensures stable device temperature during continuous or pulsed operation.
Mechanical Strength Under Thermal Stress
Tungsten's high modulus and low thermal expansion provide structural reinforcement, preventing deformation, warping, or cracking under repeated thermal cycling. This robustness makes the heat sink ideal for long-term high-power applications.
Precision Manufacturing Through MIM
MIM enables near-net-shape production of complex geometries such as micro-channels, asymmetric bases, and fine mounting features. Compared to CNC machining, MIM offers:
- Higher dimensional repeatability
- Superior material utilization
- Lower production cost for medium to large volumes
- Capability to produce thin-wall and compact structures without mechanical distortion
Long-Term Reliability
The tungsten-copper structure exhibits low thermal fatigue, oxidation resistance, and stable thermal conductivity over extended operating life, ensuring dependable performance in next-generation optical communication systems.
Overview
The NEWLIFE Tungsten Copper Heat Sink is engineered for applications that demand high-efficiency thermal control within extremely compact optical and photonic systems. By combining tungsten's high melting point and mechanical strength with the excellent thermal conductivity of copper, this composite material delivers superior heat dissipation and structural stability.
Using advanced Metal Injection Molding (MIM) technology, NEWLIFE produces heat sinks with uniform density, fine microstructure, and complex geometries that would be difficult or cost-prohibitive to achieve through conventional machining. Our self-developed tungsten and copper powders ensure stable sintering behavior, consistent shrinkage, and high bonding quality between the metallic phases, enabling reliable performance in high-power optical engines and precision semiconductor modules.
Applications
