Suggested materials (unless othwerwise required):

For best quality and cost:
300 series stainless steel 0.001 inch thick or under.

Gas, Liquid, Material FLOW Oriented:

Leak test grade;

The emphasis normally on roundness is replaced by orifice area specification to improve cost effectiveness. To optimize quality, materials should be kept as thin as allowable. 300 stainless steel is suggested unless otherwise required.

Metered Flow;

Same as Leak Test above.

Dies (wire polymer), Jets (liquid or gas);

Up to 0.010 inch (0.254mm) diameter x 0.010 (0.0245mm) deep

X-ray shielding, selective:

Typical materials are tantalum, tungsten and platinum.

Special Micro Patterns:

...........per quote.

Round, square, rectangular, slit, arc, hexagon, octagon, annular, etc. and combinations of patterns or arrays.

Four-Bar Patterns:

Standards are: 300 stainless steel 0.0005 in. x 0.375 in., or copper 0.001 in.

...........per quote.
