These steel spheres with a diameter of 8 mm are great for joining with magnets. And when combined with rod magnets, you can build some pretty crazy structures.
The steel balls are made of high carbon chromium steel that contains 1% carbon and 0,5 %–1,65 % chromium. The spheres are plated with nickel (Ni-Cu-Ni).
