What is the corrosion resistance of Cupronickels?

Cupronickel alloys provide excellent corrosion resistance, particularly in seawater.

What is the composition of cupronickel?

In principle, a cupronickel can contain between 1% and 49% nickel, such that copper remains the main element.

Are cupronickels magnetic?

Cupronickels have a very low magnetic permeability <1.01.

What is the electrical conductivity of copper like?

Copper is an excellent electrical conductor, only bettered by silver, explaining why it is used in domestic electrical wiring.

What is the difference between Alloy 400 and Alloy 500?

There is negligible difference in the composition of Alloy K500 versus Alloy 400, but Alloy K500 is appreciably stronger.

What is the thermal conductivity of copper alloys?

Copper has excellent thermal conductivity, explaining its widespread use in household implements such as pots and pans.

What are brasses?

Brasses are copper-based alloys with additions of zinc. They are typically very formable and bright yellow in appearance.

What are bronzes?

Bronzes are copper-based alloys typically with additions of tin, aluminium and silicon.

How many types of copper alloys are there?

There are perhaps 400 or more different copper-based alloys.

For duplex grades, what is the difference between S31803 (F51) and S32205 (F60)?

S32205 (F60) is produced to the upper end of the alloy specification of S31803 (F51), to give improved corrosion resistance.

Which is better, nickel or stainless steel?

With such a wide range of different alloys available, it is quite possible that several may all be suitable for a given application.

What is the difference between nickel alloys and nickel-copper alloys?

Nickel-Copper alloys are those where copper is the main alloying element to a base nickel composition.
