SILICON BRONZE (AMS 4616)

Product catalog summary

Product Overview:
Silicon Bronze (AMS 4616, C65620) is a high-strength alloy offered in solid bars, known for its excellent bearing and load properties due to its unique composition. The alloy's additional iron content enhances strength, while silicon provides self-lubricity, making it ideal for machining into ball bearing cage assemblies.

Typical Uses:

Aerospace applications
Anti-friction bearing cages, races, and spacers

General Notes:
All materials are DFARS compliant and come with microstructures. Popular sizes are readily available from stock.

Sizes Available:
Solid bars ranging from 5/8” to 4 1/2” in diameter.
