It is not possible to harden or increase its strength by heat treatment. It can only be improved by work-hardening methods of cold working. However, the phosphor bronze products in the hard state can be annealed at low temperature (to eliminate residual stress), which can slightly increase the strength. The higher, the finer the grains, the higher the added value after annealing
The elasticity of beryllium copper is very good, but because of the toxicity of beryllium, many industries are gradually looking for alternative materials. The elasticity of phosphor bronze in copper alloys should also be said to be good. It is generally used for elastic components, but still cannot be used with beryllium copper compared to.
Phosphor bronze usually needs nickel plating, beryllium copper needs heat treatment to obtain good elasticity, beryllium copper is much more expensive than phosphor bronze.
