Our Friction Stir Welded Heat Sink, designed specifically for high-power electronics, provides the ultimate thermal solution. It utilizes advanced solid-state welding to create a robust bond between a high-thermal-conductivity baseplate and dense cooling fins, achieving thermal performance comparable to a single piece of metal.
Your Professional Customized Heat Sink Manufacturer and Provider in China
Product Introduction:
As electric vehicles, renewable energy inverters, and industrial drives advance towards higher power density, the heat generated by core power devices (like IGBTs and SiC) grows exponentially, demanding unprecedented efficiency and reliability from thermal solutions.
Our Friction Stir Welded Heat Sink, designed specifically for high-power electronics, provides the ultimate thermal solution. It utilizes advanced solid-state welding to create a robust bond between a high-thermal-conductivity baseplate and dense cooling fins, achieving thermal performance comparable to a single piece of metal.
Solution Highlights:
- Manages High Heat Flux: The extremely low interfacial thermal resistance rapidly spreads heat from localized hot spots across the entire sink, effectively preventing chip failure due to overheating.
- Long Lifespan & High Reliability: The absence of brittle intermetallic compounds at the weld interface avoids the fatigue failure common in brazed joints caused by CTE mismatch, significantly extending device lifespan.
- Flexible Custom Design: The process supports various material combinations (e.g., copper base with aluminum fins), allowing for topology optimization and complex channel designs based on specific power loss and space constraints, achieving the best balance between cooling and weight.
Choosing our FSW heat sink means selecting a durable and efficient core thermal component for your critical power electronics.

EIGHTBOND
aluminum is a recently born company backed by years of experience in the lighting sector specializing in the design and supply of aluminium profiles for LED strips.
EIGHTBOND
aluminum products combine high quality with excellent price and feature an Italian design.
Our extensive range of aluminium profiles together with our experience and fast delivery time make us a very competitive company able to offer a great variety of bespoke solutions.
DARKROOMANDGONIOPHOTOMETER
Innovation and technology play a key role in our company. This is why we have recently installed a Dark Room with a Goniophotometer.
Light direction and intensity depend on many aspects, such as LED’s characteristics, the distance from the diffuser, the diffuser’s material, the shape of the profileitself.
In order not to neglect these factors and provide reliable results we have tested our aluminum profiles with each diffuser. Photometric tests have been carried out using 14,4W/m and 9,6W/m LED strips with chip LED 2835.
We can also carry out photometric tests on LED strips provided by customers.
Thanks to this extremely high-tech and latest generation device we are able to provide a valid support in choosing the most suitable profile for your lighting projects.
