Why is MOHAWK amorphous ribbon an excellent heating element for moderate temperature heaters?
Due to the absence of crystalline structure, amorphous ribbons have higher electrical resistance than crystalline solids of the same composition. Together with the physical form of the ribbon, which provides a low mass to surface area ratio, it makes the ribbon a very attractive candidate as a heating element. Why? The explanation is very simple: energy transfer from any heating element is proportional to its surface area and the temperature difference between the heater and its environment. The larger the surface area, the lower the temperature difference needed to transfer energy from the heater to its environment. Since the surface area of the ribbon is relatively large (compare it with the surface area of a conventional wire used in many heaters) it is able to efficiently transfer heat to its environment at lower temperatures. In a domestic heating environment, lower temperature means a healthier environment and greater safety and durability.
