Summary of Attachment 1 - Requirements (70Z03826QK0000015)

This is a requirements document for federal contract 70Z03826QK0000015 detailing materials to be procured. All materials require a Certificate of Conformance (COC). The contract encompasses 19 Contract Line Items (CLINs) for various aluminum, stainless steel, and specialty metal products. Aluminum products include flat bars, plates, round tubes, angles, and channels in multiple grades (6061, 7050, 2024, 7075) with hardness specifications ranging from T6 to T7451. Stainless steel items consist of 17-4PH round bars in two diameter sizes (0.500 and 1.000 inches), both tempered to H1025 condition. Steel components include square tubes in A500/A513 welded construction with dimensions ranging from 1.000 x 1.000 x 0.120 inches to 2.000 x 2.000 x 0.120 inches. The final CLIN specifies a 4130 alloy round with CD normalized hardness.

Quantities vary significantly across CLINs, from single units to 26 pieces. Lengths range from 36 to 288 inches, with several CLINs including special cutting instructions specifying piece counts and tolerances (typically ±0.125 to ±0.250 inches). CLIN 11 references a detailed technical drawing showing an obtuse angle with a 115-degree radius. CLIN 16 references an external specification document (TMS60-36039-specifications.pdf). These materials appear to be raw stock components for aerospace or industrial manufacturing applications, requiring precision dimensions and documented material certifications.
