38 Series White Aluminum Oxide Lapping Compounds
Engineered for precision, the 38 Series White Aluminum Oxide Lapping Compounds deliver a controlled, consistent finish across a wide range of materials—from hardened steels to delicate alloys..
Discover the 38 Series White Aluminum Oxide Lapping Compounds
At the core of every 38 Series compound is high-purity aluminum oxide (Al₂O₃), a premium abrasive known for its exceptional hardness, durability, and chemical stability. With a Mohs hardness of approximately 9, it provides efficient material removal while maintaining excellent surface integrity.
Unlike more aggressive abrasives, white aluminum oxide offers a balanced cutting action—removing material efficiently while producing a smoother, more refined finish. It tolerates higher pressures without breaking down prematurely, making it ideal for applications where precision and consistency matter more than speed.
