Key features of QQ-N-286

The wrought nickel-copper aluminium created by Copper Alloys has additions of iron, manganese and titanium which helps to produce a range of various properties from increased strength to corrosion resistance.

This Nickel Copper Alloy has exceptional corrosion resistance, including saltwater corrosion resistance and notable resistance to steam at high temperatures.

QQ-N-286 is also resistant to corrosion in hydrochloric and hydrofluoric acid in non-aerated conditions, emphasising its durability in demanding environments.

This unrivalled resistance to corrosion, high quality strength capacity and good weldability for use in components of all sizes makes our nickel-copper alloy a metal capable of high performance and reliability in a variety of environments and circumstances.

Frequently Asked Questions

What is QQ N 286 used for?

Due to the high corrosion-resistance of QQ N 286, it is perfect for a variety of uses in the marine and naval industries, oil and gas (such as offshore platforms and drilling equipment), aerospace industry and chemical processing industry.

What are the differences between QQ N 286 Rev F and Rev G?

Rev F refers to an older version of a federal specification. It is designed for components that must be solution annealed at 2050°F because of the presence of titanium carbide. Rev G is produced to pass the slow strain rate tensile test. It is best suited for applications where intergranular cracking is not an option.
