--symmetric [File]
will use CAST5 by default, but you can change that choice by using
--cipher-algo option.
Or better yet, you can define a permanent list of preferred encryptions in
--personal-cipher-preferences : the first one will be used for symmetric.
AES is "S7"
Example:
personal-cipher-preferences S7 S1 S10 S3 S4 S2
Of course, each time you make a symmetric encryption, you'll need to type a
PassPhrase (but not the one you are using for your secret key), and the
recipient must have that PassPhrase in order to decode.
