Metallic Grinding Media

Note: Sizes shown in red indicate the media is recommended for use in bead mills except where stated otherwise.

Through-Hardened Carbon Steel Balls

Through-Hardened Carbon Steel Balls Type 1065

Through-Hardened Carbon Steel Balls are magnetic and can be used in the food industry along with 440C stainless steel media. They are a low-cost media that are superior and recommended over case-hardened carbon steel media.

  • (SAE 1065-through-hardened)
  • Specific Gravity: 7.8
  • Hardness: ROCKWELL C 60–62
  • Relative Cost: LOW
Chrome Steel Balls

Chrome Steel Balls Type 52100

Chrome Balls (steel type 52100) are through-hardened and tempered steel balls designed to achieve maximum strength and quality. Ball hardness is in the 60–67 HRC range.

  • Specific Gravity: 7.8
  • Hardness: ROCKWELL C 60–67
  • Relative Cost: Low to Moderate
440C Stainless Steel Balls

440C Stainless Steel Balls

440C Stainless Steel Balls are through-hardened and tempered throughout for maximum strength and quality. They are magnetic and corrosion-resistant.

Alumina Balls and Satellites Grinding Media

Alumina Balls and Satellites

Union Process is one source of 90%, 94%, 99.5% and 99.9% alumina media. 90% alumina is available in satellites and rod/cylinders. 94% alumina balls have excellent wear resistance with higher impact strength to save running costs with less contamination. They have great wear rate generally better than 90% or 99.5%. 99.5% alumina balls have the highest alumina content for a moderate price. The 0.5% impurity is MgO that is added to inhibit grain growth during sintering in the kiln. There is less than 0.1% silica in the media. 99.9% alumina balls are made of very pure and reactive raw materials for high purity alumina applications where contamination is a factor.

Alumina Grinding Beads

Alumina Beads

Alumina Beads are specially formulated to be used in high-energy mills in which a high degree of fineness is required. They are used in various industrial fields such as inks, paints, advanced ceramics, mining, cosmetics and pharmaceutical industries. They are a perfectly spherical shape with high mechanical properties and high wear resistance at a moderate price.

  • Specific Gravity: N/A
  • Hardness: Mohs 9, VICKERS (0.5 kg) 1200 ± 50
  • Relative Cost: Low to Moderate
Glass Grinding Beads

Glass Beads

This grade is used for milling applications with 85% roundness. All Glass Beads are lead-free and less expensive.
