Metal matrix composite is RoHS compliant
A CPS Corp product story

AlSiC metal matrix composite is ideally suited for thermal management solutions for high brightness LEDs.
AlSiC (aluminium silicon carbide) metal matrix composite is ideally suited for thermal management solutions for high brightness LEDs.
AlSiC has been tested and meets the requirements of the Restriction of Hazardous Substances Directive of the European Parliament.
AlSiC enables a tailored coefficient of thermal expansion (CTE), offering compatibility with various electronic devices and assemblies.
Unlike traditional housing materials, the isotropic CTE value of AlSiC can be adjusted for specific applications by modifying the Al-metal/SiC-particulate ratio.
Meeting the increased thermal behaviour requirements for high brightness LEDs, AlSiC also exhibits a high thermal conductivity that results in extremely efficient thermal dissipation.
Coupled with its superior CTE matching, AlSiC's high thermal conductivity effectively dissipates heat that can influence LED brightness, efficiency, colour, and efficacy and product life time.
The CPS AlSiC near and net-shape fabrication process both produces the composite material and fabricates the product geometry, resulting in a cost-effective product and allowing rapid prototyping for high volume advanced thermal management solutions.
The unrestricted geometry of AlSiC enables the cost-effective inclusion of design features such as cavities, pedestals and alignment features.
The unique casting process enables integration of very high thermal conductivity inserts or cooling tubes for more advanced thermal management solutions.
