اقرأ أكثرHeat conductivity is a very important property when deciding which metal to use for a specific application. As copper is an excellent conductor of heat, it's good for heat exchangers, heat sinks, and even saucepan bottoms. Because steel is a poor conductor of heat, it's good for high-temperature environments like airplane engines.
اقرأ أكثرThe best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. The wide use of pure silver has a couple of drawbacks. First, it tends to tarnish with usage, which causes issues related to 'skin effect,' i.e., the unequal distribution of current that can occur ...
اقرأ أكثرThermal conductivity is the term that describes how quickly a material absorbs heat from areas of high temperature and moves it toward areas of lower temperature. The best heat-conducting metals have high thermal conductivity and are useful for many applications, such as cookware, heat exchangers, and heat sinks.
