About this file

Written by GovTribe AI ·

This is a Questions and Answers document for RFQ 477155 that addresses three key areas of clarification regarding part manufacturing and delivery requirements.

Regarding identification and marking, the document confirms that parts may be marked using an engraving tool provided the markings meet character height and MIL-STD-130 requirements. For STEP files, the document indicates that these files are available but must be requested separately via email to Lgonzales@bnl.gov by close of business on May 11, 2026, with RFQ 477155 included in the subject line. On the subject of plating for aluminum components, the document clarifies that "Iridite" and "Alodine" are trade names for chromate conversion coatings that are acceptable alternatives to chromate, provided the process used meets MIL-DTL-5541 Class 3 specifications (clear, RoHS compliant). Contractors may use Iridite, Alodine, or an equivalent compliant process to fulfill the plating requirements.

1 Identification and Marking.

-Can the parts be marked with an engraving tool as long as they meet the character height and MIL-STD-130 requirements?

2 STEP Files

- Are there STEP Files available along with the part prints?

3 Plating

- For the aluminum components that are to be plated, I notice in the BOM of each print it lists iridite and alodine. Does this mean the chromate can be replaced with either iridite or alodine?

“Iridite” and “Alodine” are trade names for chromate conversion coatings and are acceptable, provided that the process used meets the requirements of MIL-DTL-5541 Class 3 (clear, RoHS compliant).

In short, you may use Iridite, Alodine, or an equivalent process, as long as it complies with the specified standard and class.
