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.

The spring is 10mm long, extending to 25mm in hot water.

11.5mm external diameter

9mm internal diameter
