Sandblasting Abrasive White Aluminum Oxide for Aluminum Alloy Product Surface
Introduction
White Aluminum Oxide is a high-performance abrasive material widely used in sandblasting applications, particularly for surface treatment of aluminum alloy products. Known for its exceptional hardness, durability, and consistent particle size, it ensures efficient and precise surface preparation, cleaning, and finishing. This abrasive is ideal for achieving a smooth, contaminant-free surface while maintaining the integrity of aluminum alloys.
Key Features
High Purity & Consistency – White Aluminum Oxide (Al₂O₃) is manufactured with over 99% purity, ensuring minimal impurities and uniform particle distribution for consistent blasting results.
Exceptional Hardness (9.0 Mohs) – Harder than most abrasives, it provides superior cutting performance without embedding into softer metals like aluminum.
Reusable & Long-Lasting – Unlike softer abrasives, White Aluminum Oxide retains its sharp edges longer, reducing consumption and operational costs.
Low Dust & Minimal Silica Content – A safer alternative to silica sand, it produces less dust, improving workplace safety and visibility during blasting.
Angular Grain Structure – Enhances surface profiling and adhesion for coatings, anodizing, or bonding processes.
Applications
Surface Cleaning & Preparation – Removes oxides, scales, and contaminants from aluminum alloy surfaces before coating or anodizing.
Deburring & Finishing – Smooths edges and refines surfaces without causing excessive material loss.
Paint & Coating Adhesion – Creates an optimal anchor profile for improved paint and coating durability.
Restoration & Maintenance – Ideal for refurbishing aluminum components in automotive, aerospace, and marine industries.
