There are different methods of heat treating. Each with their own unique benefits and purposes. Stress relieving of Nickel Aluminum Bronze is done at lower temperatures than annealing. This is really useful when the Nickel Aluminum Bronze is being machined into thinner walled bushings, like those used in aircraft landing gears. As some Nickel Aluminum Bronze bar stock can have a tendency to spring after larger amounts of metal is removed. By having the bar stock stress relieved, it is less likely to spring out of tolerance after machining.

Being that this alloy is used extensively in bushing applications, the stress relieving helps keep the close tolerance needed when machining the bushings. Annealing Generally this is done at a higher temperature than stress relieving. Annealing can cause a greater degree of microstructural change to the metal. Quenching and Tempering Nickel Aluminum Bronze reacts similarly to alloyed tool steels in respect to heat treatment procedures.

A martensitic phase is formed in the alloy when Nickel Aluminum Bronze is water quenched from elevated temperatures. Once quenched Nickel Aluminum Bronze Bars can be tempered to improve ductility while still retaining a high tensile and hardness.

This gives this larger diameter greater tensile strength, improved hardness, at the same time while improving the ductility of the metal. C is a cast alternative to C In this alloy heat treatment is used to give this cast alloy similar mechanical properties to the extruded version. This alloy is also quench hardened and temper annealed. Heat treatment can be a useful technique used to both relieve stress and improve mechanical properties in Nickel Aluminum Bronze Alloys.
