UNSPSC 31111604: Bronze impact extrusions

UNSPSC 31111604 Bronze impact extrusions, a Commodity code, covers fabricated bronze components produced through impact extrusion — a cold-forming process that shapes bronze stock into precision parts for mechanical assembly. State and local governments procure these components primarily as subordinate materials within larger infrastructure, equipment, or maintenance projects rather than as standalone line items; they appear in specifications for pumps, valves, fittings, architectural hardware, and industrial equipment where bronze's corrosion resistance and machinability make it the specified material. Issuing bodies sourcing under this code span state transportation and public works departments, municipalities, water and sewer authorities, and county maintenance operations, typically bundling bronze extrusions into broader capital or O&M contracts for infrastructure systems.

The source provided contains no recent state or local contract opportunities tagged to this code, so current activity and geographic concentration cannot be characterized from recent procurement records.
