Abstract: Solving the problem of breakage of beryllium, copper contacts by applying heat shock to a condition just short of visible oxidation and then promptly water quenching is disclosed. After being so treated, the contacts are then processed in the traditional way which normally anticipates an acid rinse, and subsequent plating. The product of the process can be definitely identified by bending. If not annealed, it will break by bending more than 45.degree.. If annealed properly in accordance with the process of the invention, it will withstand three or four bends to 90.degree. before breakage. Where a compliance section exists in the contact, it is important that it be in the zone of applying the heat shock so that after the heat shock annealing process is concluded, the compliance section will behave like a softer material.
