For Heat Exchange Devices, You Need the Right Material and the Right Partner

The material used to manufacture heat exchange devices such as heat pipes, heat sinks, and header bars has a direct impact on the performance, efficiency, and reliability of the product. This is why aluminum extrusions are in high demand in healthcare, lighting, construction, computers, electronic devices, and especially the military and aerospace sectors.

The case for aluminum extrusions in the manufacturing heat exchange devices is rock solid.

  • High thermal conductivity (six times better than steel) to optimize the heat transfer process, maintain the stability of the metal, and withstand high temperatures.
  • Exceptional corrosion resistance, which is especially important in saltwater environments.
  • Lightweight yet strong and durable, which is ideal for cooling applications.
  • High malleability, which enables customization of intricate aluminum extrusion profiles with close tolerances.

From parts you can barely see to larger designs up to 3.5 inches (8.89 cm), Minalex is capable of producing aluminum extrusions to tight tolerances. We regularly produce aluminum extrusions with tolerances as tight as +/- .001 inch (0.025 mm) on one or more dimensions of an extrusion, walls as thin as 0.020 inch (0.4572 mm), and holes as small as 0.060 inch.

Minalex is fully certified as an AS9100D and ISO9001 company with AMS, MIL, and QQ specifications to ensure every heat exchange device we manufacture meets strict military and aerospace standards.

We can produce aluminum extrusions in every imaginable shape and design for heat exchange devices in high or low volumes, which means we can develop prototypes to precise specifications. We also have the experience to choose the right aluminum alloy for your application (e.g., aerospace extrusions) to maximize performance and efficiency.

For example, alloy 6061 provides exceptional strength, durability, and heat transfer, while alloy 3003 provides superior corrosion resistance and workability.

Whether you need heat exchange devices in standard shapes and sizes or new, innovative solutions for military or aerospace applications, Minalex can guide you through the process. Contact us today to schedule a consultation.
