What’s up guys?!?!?! Michael here… back for the one hundred and thirty third time. For the last few weeks, we have been talking about popular Brasses……… Copper alloys with Zinc as the major addition.

Today we are moving on to a Bronze. There are many types of “Bronze”.

630 Bronze, UNS designation C63000 is classified as an Aluminum bronze… Aluminum is the major alloying element with lesser amounts of Nickel,  Iron, and Manganese making up its chemical composition.

Most commonly used in a cold worked condition followed by a stress relief to provide increased strength and wear resistance.

Typically used in parts requiring its strength, corrosion, and wear resistance.

Chemical Composition – UNS C63000 – AMS 4640
Aluminum9.0 – 11.0 %
Nickel4.0 –  5.5 %
Iron2.0 – 4.0 %
Manganese1.5 % Maximum
Zinc0.30% Maximum
Tin0.20% Maximum
Silicon0.25 % Maximum
