Abstract
The clad metal comprises a soft metal lamina overlay on a refractory metal lamina. An orifice is created by first punching a hole through the clad metal and then etching the soft metal lamina around the punched hole to create in that portion of the hole in the soft metal lamina a tapered entrance to that portion of the hole in the refractory metal lamina. The soft metal lamina is copper and the refractory metal lamina is molybdenum.
