COMMON METALS WE WORK WITH

Our photochemical machining process is compatible
with a wide range of metals.

Aluminum

Aluminum is easily machinable and suited for producing thin metal parts in any quantity.
It is available in different grades and alloys.

Nickel Silver

Nickel silver etching with chemicals enables the precise alteration of a metal surface without the burrs
or other unwanted distortions associated with laser etching.

Stainless Steel

Etching steel involves anything from creating lines and grooves to fabricating precision metal parts with
dimensions that account for tight tolerance requirements.

Nickel

Photo etching nickel can generate a number of attractive design features that are difficult to achieve
with alternative metal etching methods.

Beryllium Copper

Photo etching beryllium copper provides several production benefits that cannot be matched by processes
such as stamping or laser cutting.

Copper

Chemical machining is preferred for copper and other metal parts because they’re not easily
damaged in the process.
