Bandsaw blade width?

[wilhurley]

I have a metal bandsaw similar to those harbor freight ones for 149.00.
My question is the blade on it is about 1/2 inch wide. But I was wanting to use a thinner blade someting around 1/4 inches to give me more room to make curves. It takes 64 1/2 inch blades.

I have run 1/4" wood cutting blades on them but have never seen 1/4 metal cutting blades.

The narrower blades are not too difficult to run but rubber covered wheels would be a big help..
