Our aluminum heat sinks are designed in a way that is the most cost effective solution for cooling a majority of electronic devices. We use 6063 or 6061 aluminum alloy, which with excellent thermal and mechanical properties. Heat sink parts are made with all features necessary for cooling electronic components, such as audio amplifier, insulated-gate bipolar transistor (IGBT), silicon controlled rectifier (SCR), metal-oxide-semiconductor field-effect transistor (MOSFET), and so on. Fins are tapered with engineered sizes to achieve the maximum heat dissipation.
