UNSPSC 11172001: Aluminum alloy 7178

Aluminum based alloy with the following main characteristics: Zn 6,30 to 7,30 percent, Mg 2,40 to 3,10 percent, Cu 1,60 to 2,40 percent, Fe 1,00 percent, balance equals Al + minor metallurgical pollutions. Alloy 7178 is a high strength alloy with magnesium and copper as the major alloying elements. It is heat treatable and develops improved mechanical properties from precipitation hardening.

UNSPSC 11172001 Aluminum alloy 7178 is a Commodity code that in recent state and local practice encompasses coiled aluminum stock for specialized manufacturing and fabrication applications. The code appears in procurement for license plate production, welding repairs, and equipment fabrication rather than finished aluminum products or raw materials for general use. State and local governments sourcing under this code include state departments (Colorado Department of Corrections), county governments (Hillsborough County, Florida), and judicial bodies (Los Angeles Superior Court). The Colorado Department of Corrections has emerged as a repeat buyer, soliciting coiled aluminum alloy 3105H21 in multiple procurements for its tag plant operations. Scope includes raw aluminum coil stock meeting specific metallurgical standards—tensile strength, yield strength, elongation, and embossing performance—along with surface treatment specifications and dimensional tolerances for production-line use.

Recent activity centers in Colorado and Florida. The Colorado Department of Corrections issued three separate IFB notices for coiled aluminum 3105H21 in May and August 2026, seeking 350,000 pounds and 10,000 to 70,000 pound increments respectively for license plate manufacturing at Canon City. Hillsborough County Board of County Commissioners posted an ITB on August 26, 2026 for mobile welding and fabrication services (estimated $207,429.10 over three years) that, while primarily welding-focused, includes materials procurement for equipment repair and fabrication. The Los Angeles Superior Court solicited pallet rack wire decking in April 2026, which does not align with the aluminum alloy 7178 code scope and suggests a tagging mismatch. Colorado's repeat procurements under this code indicate standing demand for coiled aluminum stock meeting strict embossing and tensile-strength specifications, with delivery to correctional facilities and structured pricing on a per-pound basis subject to firm pricing and monthly delivery schedules.
