The Comprehensive Guide to 3mm-50mm High-Density Aluminum Oxide Alumina Milling Balls

Introduction

What are 3mm-50mm High-Density Aluminum Oxide Alumina Milling Balls?

Key Features of Alumina Milling Balls

1. High Density and Hardness

• Density: Typically around 3.6 g/cm³, these balls are denser than many alternative materials, providing greater impact force during milling.
• Hardness: With a Mohs hardness of 9, alumina balls are extremely resistant to wear, ensuring longevity and consistent performance.

2. Versatile Size Range

• Available in sizes from 3mm to 50mm, allowing for customization based on specific milling requirements.
• Smaller balls (3mm-10mm) are ideal for fine grinding, while larger balls (20mm-50mm) are used for coarser materials.

3. Chemical Stability

• High purity alumina (>92% Al2O3) ensures chemical inertness, preventing contamination of the milled materials.

4. Surface Finish

• Polished surface reduces friction and wear on milling equipment, enhancing efficiency and lifespan.
