What is Mixed Alumina?
Mixed alumina is a hard and durable abrasive that stands out due to its high efficiency in surface treatment. It is commonly used in the metal, glass, and ceramics industries to remove contaminants, clean surfaces, or prepare them for subsequent treatments. Mixed alumina is a mixture of high-grade and regular alumina, providing a unique combination of hardness and resistance.
Key Properties of Mixed Alumina
High Hardness
Mixed alumina has a high Mohs hardness, making it ideal for processing hard surfaces.
Durability
It has a long lifespan and can be reused multiple times.
Effective Blasting Action
The sharp edges allow for quick and efficient surface processing.
Longevity
Thanks to its high stability, mixed alumina can be used for a long time, saving costs and increasing efficiency.
Technical Data of Mixed Alumina
Mixed alumina is characterized by its special technical properties, making it ideal for a wide range of applications:
Material Composition
Mixed alumina consists of a mixture of high-grade alumina and regular alumina, known for their exceptional hardness and durability.
Grain Sizes and Distribution
Mixed alumina is available in various grain sizes, from fine to coarse, depending on the application. Finer grains are suitable for precision processing, while coarser grains are used for fast and intensive processing.
Hardness and Density
With a Mohs hardness of 9, mixed alumina is one of the hardest abrasives. Its high density contributes to the effectiveness of the blasting process, ensuring an even distribution on the treated surface.
Applications of Mixed Alumina
Mixed alumina is used as an abrasive in various industries and offers versatile application possibilities due to its properties:
Abrasive for Surface Treatment
Mixed alumina is primarily used for cleaning, deburring, and finishing surfaces. Its sharp edges reliably remove unwanted layers such as rust, paint, or contaminants and prepare the surface for further processing steps.
Used in Metalworking
Due to its high hardness, mixed alumina is excellent for removing rust, paint, and scale from metal surfaces. It is often used to prepare surfaces before painting or coating.
Glass and Ceramics Industry
Mixed alumina is particularly suitable for fine blasting applications in the glass and ceramics industry, where precision work is required. It allows gentle treatment of delicate surfaces without damaging the material.
