What is “C95520 / AMS 4881 Nickel” Material?

C95520 is a nickel-aluminum bronze alloy covered by AMS 4881 for high-performance cast applications. Its alloy system is designed to provide high strength and hardness together with useful wear and corrosion resistance, making it suitable for demanding engineered components.

AMS 4881 material is associated with aerospace and other high-performance bearing applications where controlled chemistry, heat treatment, dimensional stability, and traceable certification are important. Potential applications include aerospace bushings and bearings, hydraulic and mechanical components, wear components, pump parts, marine hardware, and other highly loaded components.

The applicable manufacturing process, heat-treatment condition, dimensional requirements, and inspection requirements should be established from the governing AMS 4881 revision and the customer drawing or purchase order. Where required, TCA can coordinate chemical certification, mechanical testing, nondestructive testing, heat-treatment documentation, and other quality records.

Tough Copper Alloys can support OEM and aerospace programs requiring AMS 4881 / C95520 cast components and engineered rough-machined blanks. Each program should be reviewed against the customer’s exact specification, required form, and certification package before production.
