💡 What’s the benefit of using zirconia ceramic balls instead of steel ones?
Zirconia balls are a top pick when you need extreme smoothness, zero magnetism, and chemical durability:

• No corrosion in water, acids, or salt spray

• Electrically insulating (great for non-conductive setups)

• Up to 50% lighter than steel, less inertia in spinning parts

• Won’t magnetize, perfect for sensitive sensors or medical gear
