Black Anodized Flat Heat Spreader

Product Overview

A flat aluminum heat spreader with a black anodized surface. The black anodic layer significantly raises thermal emissivity, adding a radiative heat path alongside conduction and convection—particularly effective in sealed or poorly ventilated enclosures. Flat plate edges allow easy gasket-sealed assembly with O-rings or sealing strips.


Technical Highlights

  1. Black anodic layer raises radiative efficiency and provides corrosion resistance
  2. High flatness and straight edges suit sealed and surface-mount assembly
  3. Mounting holes, studs and locating features can be cast directly into the plate

Manufacturing & Customization

Anodic coating thickness and color can be controlled to customer specification. Where higher airtightness is required, porosity is managed during casting and sealed by impregnation.
