Aluminum Bronze C63200
Specs: QQ-C-465 ASTM-B-150 ASTM-B-124 MIL-B-24059
UNS# C63200
C63200 Nickel Aluminum Bronze ASTM B150 is predominantly a Copper alloy (78-82%) with Aluminum, Nickel, Iron, and Manganese. It is a heat-treated alloy that is a strong, corrosion-resistant material that performs well at high and low temperatures, C63200 also has a low magnetic permeability making it ideal for instrumentation systems.
Commonly used in naval sea applications of commercial and military variety. C63200 is used in valve assemblies, stems & seats, pump shafts & sleeves, and various components in marine, aerospace, and oil patch industries.
Details
Aluminum Nickel Bronze (CuAl9Fe4Ni4) C63200 is an American Naval alloy with improved corrosion resistance. When the alloy was first produced as a casting, it was found that occasionally the alloy suffered selective corrosion of the kappa phase.
The new wrought alloy has a quench and temper heat treatment which eliminated this problem introducing a structure that changed the morphology of the kappa phase.
The alloy has a proven history within Naval applications where it is used extensively in the building of Nuclear submarines and other Naval surface craft.
C63200 can be joined by using MIG or TIG welding techniques.
In addition, the alloy has excellent wear resistance and good corrosion resistance in fresh and seawater.
It is non-sparking which is important in explosive environments, relating to weapon handling, petrochemical industries, and the mining industry.
It has also good erosion/corrosion properties, which find applications for marine propulsion units such as propellers.
Available shapes – round, hex, rectangular and square
