Metalightest Aluminum Graphite Composite ALG
WHY YOU NEED
High-power, high-density electronic components make thermal management more and more important, and thermal management is directly related to the performance and reliability of components. Furthermore, lightweight is in need in certain areas.
WHAT WE HAVE
Metalightest ALG is equipped with high heat exchange efficiency and lightweight. Key materials can make the industry decisively competitive.
Introduction ALG
high heat exchange efficiency
Aluminum Matrix
Thermal Reinforcement
high thermal emissivity (~0.98)
light-weighted (2.7 g/cm^3)
high thermal conductivity (230 W/mK)
high stiffness
Performance Test
A closed system with natural convection only.
Heat source temp is the performance index. The lower the better.
dummy closed box (200*200*100mm)
tested sample (100*100*1mm)
heat source die (40*40*5mm 7Watt)
Based on heat source temp vs. time plot. ALG shows better performance than aluminum and copper.

Dimensions: 40mm*40mm*10mm (16000 mm^3)
Weight: 15.8g
ALG Ultra Thin Thermal Fin (122.1°C to 84.8°C)
Conventional Thermal Fin (122.1°C to 90.2°C)
ALG Ultra Thin Thermal Fin
Applications
Power Supply
Tower Cooler
Drone
Solar Panels
ALG makes portable devices lighter, cooler, more effienct and more reliable
Thermoelectric Chip
-
Single-chip hot side 80℃
-
without ALG 0.17V 20mA
-
with ALG 0.33V 42mA
ALG can further cool down the cold side of the thermoelectric chip to improve the efficiency
ALG Thermal Pads
Applications
Sport Cameras
DJI Action2 and GoPro 10 suffer from overheating problems when the high-resolution mode is used. Metalightest ALG thermal pads alleviate the problem and extend 20% recording time.
ALG Thermal Pads
Applications
Smartphones
❅ Needless to say, smartphones are getting warmer which is bad for performance
❅ By installing ALC thermal pads, performance can be sustained

Applications
Notebooks
❅ Notebooks are getting thinner but higher CPU temp leads to worse performance
❅ By installing ALC thermal pads, performance is better with lower CPU temp and lower thermal fan RPM.
