I don't know about seeds but I've used aluminum pans for years for cuttings without any adverse effects. Some pans have held the same cuttings for at least 3 years and the plants are thriving. Eventually they corrode to the point of being ready for the trash heap so I just go buy a new stack of them at Sam's Club (15 full size for less than $10 or 30 half size for about the same price). They also make effective drip pans for a few years.
