If, by alphanumeric data, you mean that you do not need anything else than simple standard western characters, without accentuation, typically only letters and numbers, then I would go for a char([your length]).

If not, then a nchar([your length]) could be appropriate.

As the original poster you should apparently see a green tick next to the solution that solved your problem (you can indicate that more than one solution worked for you if you want to).
Failing that, don't worry about it.

Solution 1

(n)varchar is most suitable for alphanumeric fields. Simple (n)char will pad text with spaces.
