I'm not convinced its the blade that's causing the problem. What TS are you using?, fence setup etc?.

My current aluminium cutting blade is a CMT, 235mm, triple chip grind, 6 degree neg. rake, 48 teeth. I agree with Jack that the blade you've linked to appears to be negative rake. I can't understand why you're not getting a relatively clean cut from it regardless of what you paid for it. Makes me wonder whether there is something else going on.
Have you tried cutting a piece of timber with it?

When you have eliminated the impossible, whatever remains, however improbable, must be the truth, also eliminating the most obvious first is always a good place to start.
Elementary my dear Beaver.

Blade on backwards
- its not the first time this has happened - It even happened to an experienced woodie on this site who seems to have evaporated.
Negative rake applies to the forward facing face of the tooth - when on backwards in practice it becomes a hyper negative rake which will still cut but will get super hot hence the excess galling.
