Heat Treatment of Beryllium Copper.

The age precipitation process increases hardness and strength of beryllium copper which is very stable during stamping, cutting or machining. This heat treatment removes internal stresses, and the components do not lose their shape and precision.

Heat Treatment Process:Beryllium copper passes through two principal processes which include solution annealing and age hardening.

Solution Annealing: The alloy is heated to slightly below the solidus temperature, whereby beryllium dissolves in a supersaturated solution. When it is quenched in water, it forms a soft, ductile metal that is available to be formed, drawn, or rolled.

Age Hardening: This is also known as precipitation hardening, and it is the process where the annealed alloy is heated to a temperature that is lower than the solvus point then left to cool slowly. Beryllide phases that are precipitated enhance the strength of the metal making beryllium copper hard and strong. Common conditions include:

• Under Aging: Makes ductile and tough, medium hard.
• Peak Aging: Maximizes hardness, strength and electrical/thermal conductivity.
• Over Aging: It results in thermally stable, ductile and strong components.

This alloy is the best to use in industry due to its combination of superior beryllium copper hardness, strength and machinability.
