This might be the best deal on 1 inch steel balls so I'd go for these if you need it. I've used them on several magnet projects where I have 1"N52 magnet bars. and then smaller balls on top of them. It's a heavy ball so you can't build it too high, but it works really well. I'm not me sure what other uses I need them for, but they're sleek and look great.
