Description

2.1504 (CuNi14Al3) is an extra high strength copper nickel alloy developed by Columbia Metals that maximises both strength and corrosion resistance. Sometimes referred to as a nickel bronze, NIBRON® contains additions of aluminium, iron and manganese that join with the copper and nickel to achieve its exceptional properties. Although suited primarily to the tough extremes of marine or offshore oil and gas environments, Nibron® has also established itself for critical components in many other industrial sectors including aerospace, electrical, chemical and automotive. It shows the following features and properties:

Very high mechanical properties

Excellent wear and galling resistance

High ductility

Outstanding resistance to marine corrosion and erosion

Retention of properties at cryogenic temperatures

Exceptionally low magnetic permeability

Good machinability and dimensional stability

Good thermal conductivity
