Aluminum Oxide Ball

Aluminum Oxide Ball(1060、1070) is a type of ball made from stainless steel

Aluminum Oxide Ball

Alumina balls are advanced engineering components known for their exceptional hardness, low density, excellent heat and wear resistance, and stable chemical composition. They are widely used in industrial fields. They are favored for their high hardness, wear resistance, high temperature resistance, and strong chemical stability.

NOT SURE WHICH ALUMINUMOXIDE BALL RIGHT FOR YOU?

Features of Aluminum Oxide Ball

  Aluminum balls offer high hardness (Mohs hardness 9) and low wear rate (<0.01%), making them wear-resistant and low-contamination, suitable for high-intensity grinding and extending equipment life.

  They are resistant to high temperatures (>1000°C) and chemically stable (resistant to acids and alkalis, except hydrofluoric acid), making them suitable for high-temperature furnaces and the chemical industry..

  Activated alumina balls have a high surface area (300-350 m²/g) and a porous structure, resulting in strong adsorption capacity and suitable for use as desiccants or catalyst carriers.

 They offer uniform sphericity, high density (3.6-3.9 g/cm³), and excellent flowability, reducing wear and improving grinding and filling efficiency.

Our Factory

Changzhou Risheng Steel Ball Co., Ltd. is located on the eastern shore of Taihu Lake, adjacent to Shanghai, with convenient transportation. Since its establishment in June 1995, the company has been dedicated to developing and manufacturing steel balls, integrating research and development with trade.

For many years, Risheng building on the foundation of the Wujin Metal Ball Research Institute, has been committed to researching steel ball manufacturing technology. We primarily produce shaft steel balls (AISI 52100), stainless steel balls (AISI 201/304/316/420/440/430), and carbon steel balls (AISI 1015/1045/1085) with diameters ranging from 0.8mm to 25.4mm, with precision grades up to G10, G40, and G100. We also offer custom specifications for alloy steel balls, military steel balls, copper balls, UFO balls, ceramic balls, and other metal balls. 

Packaging & Deliver of Aluminum Oxide Ball

High-strength inner packaging: Shockproof foam bags or custom plastic boxes are used to secure each Aluminum Oxide Ball in place, protecting it from impacts and scratches.

Moisture-proof protection: A moisture-proofing agent is added to effectively prevent the impact of moisture on the product during transportation.

Sturdy outer packaging: Thickened corrugated cardboard boxes or wooden pallets (for large orders) are used to ensure safe long-distance transportation.

Clear labeling: Product specifications, quantity, and drop warnings are clearly marked on the outer packaging box for easy verification and safe handling.

FAQ of Aluminum Oxide Ball
  • Q What are the storage requirements for aluminum oxide balls?

    A
    Store in a dry, sealed environment to prevent moisture absorption (especially for active alumina balls).Keep away from strong acids like hydrofluoric acid to avoid corrosion. N o special temperature requirements, but avoid extreme humidity.
  • Q What are the key characteristics of Aluminum Oxide Balls?

    A
    1.High hardness (Mohs 9, near diamond).
    2.High temperature resistance (>1000°C).
    3.Chemical stability (resists most acids/alkalis, except hydrofluoric acid).
    4.High surface area (300-350 m²/g for active alumina balls) for adsorption.
    5.Uniform sphericity, high density (3.6-3.9 g/cm³ for high alumina balls), and low wear rate (<0.01%).
  • Q What are the main Applications of Aluminum Oxide Balls?

    A
    1.Grinding media in ball mills for ceramics, minerals, or paints.
    2.Adsorbents/drying agents for gases and liquids (e.g., air, natural gas).
    3.Catalyst carriers in petrochemical processes (e.g., hydrogenation).
    4.Refractory materials in high-temperature furnaces.
    5.Deoxidizers in steelmaking to purify molten metal.
  • Q What are Aluminum Oxide Balls?

    A Answer: Aluminum oxide balls are spherical ceramic particles made primarily of alumina (Al₂O₃, typically >90% purity). They are categorized into active alumina balls (high porosity, for adsorption) and high alumina balls (dense, for grinding or refractory use), produced via processes like spray drying, granulation, and high-temperature sintering.
