Two Way Memory Spring
This short film from the Technology Enhancement Programme (TEP) is one of a series of clips which were produced to demonstrate the properties and use of a range of smart materials.
These springs, based on a brass alloy, ‘remember’ to open up at around 90°C and close again when cool. Such springs have many industrial applications, such as in sprinkler and fire damping systems where they replace expensive single-use only fusible links. Memory springs open and close with considerable force and are used in countless applications where movement is wanted at the opening and closure threshold temperatures.
