Profile: Langley Alloys Limited specializes in supplying unique metals for demanding applications. We carry extensive stocks of advanced duplex stainless steels, super duplex stainless steels, nickel alloys, and copper alloys in bar, plate and tube form. The Hiduron® alloys are cupronickels, so predominantly consist of copper-nickel, meaning that they have excellent resistance to corrosion in seawater, marine and industrial applications. They are strengthened by smaller additions of aluminum and iron, achieving significantly higher strengths than other copper alloys which also improves their wear resistance and anti-galling properties, making them widely used in naval and oil & gas applications.
