Any comments on the differences between 6105-T5 and 6061-T6 for 4" x 2" channels 1/8" web and 3/16" flanges that get mitered, punched and welded to self and 5052-H32? I'm accustomed to 6061-T6 but am being offered 6105-T5. Not anodized, in a general structural application at room temperature.

Any thoughts on their relative corrosion resistance to brackish waters or sour crude oil?

Many thanks!
