NEE Building

How large/small of an order will NEE accept?

We have 12 electropolishing lines operating on a daily basis, which gives us tremendous capacity to complete high-volume orders in a timely manner. That said, NEE welcomes orders from 1 unit to 50,000 units. No job is too big or too small.

What is the largest size piece that NEE can electropolish?

We have the capacity and expertise to electropolish and passivate fabrications up to 8’ long by 5’ in diameter. NEE’s staff members are skilled at designing and fabricating custom cathodes that are often critical to processing large parts to specification.

How do we obtain samples?

Simply send us your part. We’ll electropolish it and return it to you with a specific price quotation and delivery schedule. To begin the process, call 800-672-6616 or complete our brief inquiry form.

Which alloys does NEE process?

Stainless steel is the most commonly electropolished material. Most grades of 300 series, 400 series, and heat-treated stainless steel electropolish to a bright, corrosion-resistant finish. In addition to stainless steel, NEE can process additional metals in production quantities.

If you have a question about the finish of a particular alloy, NEE will process representative samples at no charge. Please call 800-672-6616 or complete our brief inquiry form.

We commonly process the following materials:

  • 300 Series Stainless Steels
  • 400 Series Stainless Steels
  • 17-4 pH
  • Inconel
  • Nickel
  • Hastelloy
  • MP35N
  • Nitronic 50
  • Nitronic 60

To which ISO standards is NEE certified?

New England Electropolising is certified to ISO 13485:2016 and 9001:2015. These designations were achieved after a stringent analysis of our quality management systems and reflect our commitment to continuous improvement.

To which electropolishing/passivation standards does NEE comply?
