Due to its good strength to weight ratio and wide range of alloy variants, aluminum is a very common alloy across a multitude of industries including Aerospace, Automotive, Power Generation, and many others.  Additive manufacturing has introduced both new Aluminum applications and alloys.  Many aluminum applications demand a low roughness surface finish for both performance benefits and/or aesthetic appeal.

REM has a range of developed, isotropic superfinishing/polishing processes for aluminum alloys.  These process technologies are applicable for both traditionally formed components via REM’s ISF® Process, as well as for AM components via REM’s Extreme ISF® Process. REM’s processes can be applied to exterior surfaces as well as internal channel applications (including cooling channels) and have been proven to produce low roughness surfaces and to increase component fatigue life in high cycle fatigue testing.

REM’s process technologies are available via outsourced processing or via installation at a customer’s site; these processes easily scale to high volume applications or can accommodate low volume, specialty component processing.  Aesthetic finishes that REM can produce range for high polish/high gloss to a range of matte variations.

Some of the many Aluminum Applications REM can assist with include:
