Specs: AMS 4616
UNS#: C65620

Silicon Iron Bronze, AMS 4616 / UNS C65620, is primarily for anti-friction bearing cages. Our Silicon Iron Bronze is controlled and tested for both grain size and hardness. It is 100% UT tested, and from a D.F.A.R.S. qualified mill.

Details

Silicon Iron Bronze, commonly known as AMS 4616, is an excellent source for anti-friction bearing cages, races, and spacers. It’s a special high strength silicon bronze with additional iron content that provides added strength in conjunction with the self lubricant of the silicon for excellent bearing and load properties.

We stock solid bar from 5/8″ to 4 1/2″ and machine blanks from 4 1/2″ to 18″.

We also produce finished machined retainers:

Ball Bearing – Completed Cages
Roller Bearing – Completed Cages
Split Retainers – Completed Cages

We are proud to say that we are the largest stocking distributor of AMS 4616 in the world.
