Kanthal A1 vs. Kanthal D
Kanthal A1 wire has a slightly higher melting temperature and tensile strength and is more commonly found in large industrial applications. Kanthal D is usually used for small home and small-scale applications.
Kanthal D would actually be more suitable for vaping due to the reduced Aluminum Content in it
