Most Tran-Tec heat sinks are made from extruded aluminum. Tran-Tec maintains a large inventory of heat sink extrusions of various sizes and configurations, many of which are de facto industry standards. Use our Extrusion Search to locate extrusions suitable for your application.
Even if you can't find an exact match for your needs we can modify extrusions by shortening fins, removing fins to provide component mounting space, cutting to a narrower width or machining features as necessary. Sample quantities of extrusions are available for evaluation. Learn more about how extrusions are made.
If your application requires a shape not in our inventory we can work with you to design a custom extrusion to meet your specific needs. Tran-Tec works with several top aluminum extruders in the U.S. who have years of experience producing in an incredible array of products.
