Kanthal A1 has a higher maximum operating temperature of 1400°C compared to 1300°C for Kanthal D. It also has a slightly higher tensile strength. Kanthal A1 has high resistivity, better wet corrosion resistance, and higher hot and creep strength. One of the main advantages of Kanthal A1 over Kanthal D is the fact that it does not easily oxidize. It is excellent for making your own coils.
