Yes, within reason in certain applications. Annealing is the process of heating the brass cherry-red to soften it. This is where a large torch is better. This works well on large brass instruments such as tubas and baritones, which get bashed hard and often. However on saxophones, this would require the removal of the bow, and separation from the bell and main body tube. If there are posts, guards, caps etc. in the area to be annealed, they are going to fall off due to the high heat. Hope this helps.
