Try fishing lure wires. Stainless and all sorts of the right size diameters. And it’s still not hard to bend. But also you can buy wire that is silver in color but still soft. I used to have some I don’t think it was aluminum because it was more pliable and not brittle like aluminum but way softer and easier to bend.
Check out Rio Grande Jewelry supply. I think this the wire I had. “Dead soft” Nickle. Metal hardness is any where from hard to dead soft. Dead soft is the most malleable.
