SUMMARY

The discussion centers on the properties of bimetallic strips, specifically the force exerted when heated and the impact of strip thickness. Participants highlight that the choice of metals, such as copper and iron, and the temperature range, starting from 150°F, significantly influence the strip's performance. The conversation emphasizes the need for precise specifications to accurately determine the force output of a bimetallic strip.

PREREQUISITES
  • Understanding of thermal expansion principles
  • Knowledge of material properties, specifically copper and iron
  • Familiarity with bimetallic strip applications
  • Basic concepts of force and mechanics
NEXT STEPS
  • Research the thermal expansion coefficients of copper and iron
  • Explore the mechanics of bimetallic strip applications in thermostats
  • Investigate the effects of varying thickness on bimetallic strip performance
  • Learn about the temperature range effects on metal bonding and force exertion
USEFUL FOR

Engineers, materials scientists, and anyone involved in the design and application of thermal sensors or actuators using bimetallic strips.

Hi there,

First post here, kinda feel as though my hand should be raised as I have a question.

The questions are ...

How much force could a bimetallic strip exert when heated? Would it matter how thick the strip was?

Thanks for answering.

Welcome to PF, Alex.
Your question as written is far too vague. What metals? What temperature range? They all make a difference..
 
Oh OK ...

A standard mix of metals, copper and iron are usually bonded together (I think?) the temperature range would from 150deg F +
