0Cr27Al7Mo2 is an iron-chromium-aluminium alloy (FeCrAl alloy) for
use at temperatures up to 1400°C (2552°F). The alloy with the
characteristics of high resistivity, low temperature coefficient of
electric resistance, high operating temperature, good oxidation
resistance under high temperature. It can equal to APM.
0Cr27Al7Mo2 resistance wire is commonly used in electric heaters
such as electric kettles, water dispensers, and electric pots. They
use the heat generated by the resistance wire to heat water to the
desired temperature, providing hot water and beverages for daily
household needs.
In ovens and microwaves, 0Cr27Al7Mo2 resistance wire serves as a
heating element, responsible for heating food to the desired
temperature. They can quickly and evenly transfer heat to the food,
ensuring effective heating and better cooking results.
- Electric Blankets and Heating Pads
Electric blankets and heating pads use the heat generated by
0Cr27Al7Mo2 resistance wire to provide users with a warm and
comfortable sleeping environment. They can evenly heat the bed
surface, alleviate discomfort from cold weather, and improve sleep
quality.
- Hair Dryers and Electric Irons
In hair dryers and electric irons, 0Cr27Al7Mo2 resistance wire is
used as a heating element to accelerate airflow or provide heat,
facilitating quick hair drying or clothes ironing.
- Water Heaters and Boilers
Water heaters and boilers commonly use 0Cr27Al7Mo2 resistance wire
as a heating element to heat cold water to the desired temperature,
providing hot water supply for bathing and cleaning needs.
