Above which temperature can iron no longer be magnetized?

1. Every ferromagnetic material has a Curie temperature above which it cannot be magnetized. 2. For iron that temperature is 1043 K, which is 770 degrees Celsius. 3. This value sits well above room temperature, so iron behaves ferromagnetically in ordinary use. 4. A value near 343 K would put the limit close to everyday conditions, which iron clearly does not show. 5. Some other elements and alloys do have Curie temperatures below room temperature. _Source: OpenStax College Physics (CC BY 4.0), Ch 22 "Magnetism", section 22.2 Ferromagnets and Electromagnets_
