I like doing something new for my job. 1450 ° F worked for annealing BeCu.

Heat Treatment of Beryllium Copper Alloys

Beryllium copper alloys offer a unique range of properties that make them the
perfect choice for a wide range of high performance applications.

One of the characteristics of this material that contributes to its robust performance
is the ability to be precipitation hardened from a soft, formable, low hardness condition
to a high strength, high hardness condition.

In addition to the dramatic increase in strength, beryllium copper alloys also
develop corresponding increases in electrical and thermal conductivity.

Many unique property combinations can be tailored with the proper choice
of thermal treatments.

Annealed (Abbreviations and codes include: A, ANN, TB00)

This is the material condition/temper resulting from heating the material to a
temperature sufficient to allow the beryllium to dissolve into a solid solution
within the copper base metal, followed by rapid cooling (quenching) to freeze the
material in this condition.

This produces the softest form of the material. This is also referred to as
Solution Annealed, Solution Heat Treated or Solutionized.

The result of proper annealing and quenching is the creation of a homogeneous,
single phase, solid solution structure.
