elements, and is also called iron-chromium-aluminum furnace wire or
iron-chromium-aluminum heating wire. The density of the furnace bar
is approximately 7.1 g/cm3 and the melting point is approximately
1500°C. It has good thermal conductivity, with a thermal
conductivity of approximately 13.5 W/m·Kelvin.
0Cr25Al5 heater wire has high strength properties, with a tensile strength between
690-930 MPa, a yield strength between 300-650 MPa, and an
elongation of at least 20%. Its specification range is 0.025-10 mm,
and the available shapes include ribbon, line, ribbon wire, plate,
etc.
This heater wire is mainly used in the manufacture of resistance heating elements,
such as heaters, electric stoves and electric stoves. It can
