2.0855 is the Werkstoff number for a copper nickel alloy most commonly known as Hidurel 5.
2.1504 is the Werkstoff number for a copper nickel alloy most commonly known as Hiduron 130.
Copper and alloys primarily based upon copper are considered non-magnetic.
The unique patina of copper and its alloys will develop over time and protects the surface from further corrosion.
Copper is an excellent conductor of both heat and electricity, only bettered by silver in both instances.
Cupronickel alloys provide excellent corrosion resistance, particularly in seawater.
In principle, a cupronickel can contain between 1% and 49% nickel, such that copper remains the main element.
Cupronickels have a very low magnetic permeability <1.01.
There is negligible difference in the composition of Alloy K500 versus Alloy 400, but Alloy K500 is appreciably stronger.
Hiduron is a trademark belonging to Langley Alloys Ltd and applies to a family of high-strength copper – nickel alloys.
Copper has excellent thermal conductivity, explaining its widespread use in household implements such as pots and pans.
Bronzes are copper-based alloys typically with additions of tin, aluminium and silicon.
