Brass Overview:

Brass has excellent thermal conductivity and thus makes heat exchangers (radiators). Its electrical conductivity ranges from 23 to 44% that of pure copper. Mostly, customers use brass into making conductive objects for various purposes, such as conductors, scientific research or decoration etc.

Currently, the largest brass sphere/ball is 500mm. For brass balls, they could be polished, matt or brushed. And sometimes, people will choose plated stainless steel spheres over brass spheres if they opt for larger sizes, such as 1000mm, regardless of material.

Please note that brass balls are handcrafted and are not perfectly round and accurate, contrary to mass-produced balls of different materials.
