MetalBall manufactures high‑precision steel and ceramic balls for critical aeronautics and space applications. Our organization and processes comply with the most demanding industry standards.
Our steel balls are manufactured from high‑performance materials (AMS standards) and undergo NADCAP‑certified heat treatment. Our manufacturing process ensures flawless quality, and all characteristics are verified in our highly qualified laboratory:
Geometric inspection
Surface‑finish analysis
NDT Eddy‑current testing and material sorting (NADCAP)
Niteau etching (NADCAP scheduled for 2026)
Our silicon nitride balls (Si₃N₄) are produced from Class 1 blanks and comply with ASTM F‑2094.
