These remarkable springs, based on a brass alloy, ‘remember’ to open up when heated and close again when cool. If immersed in hot water at or around 90°C they will open in a split second and close as quickly if dropped in cold water.

Such springs have many industrial applications – e.g., in sprinkler and fire damping systems where they replace expensive single-use only fusible links.

  • Spring weight: 3g
  • Length: 10mm, extending to 25mm in hot water
