Alloy Processing: Nitric acid-led volume
Among the 3,421 Fabricated Metals facilities in this database, Alloy Processing reports the 679th-largest volume, placing it in the top 19.8% of its sector. Its reported volume is concentrated rather than spread: Nitric acid alone is 94.9% of the total. Scale peers outside California include Hobart Brothers Co Filler Metals Operations Troy and Skyline Steel Llc-Armorel.
Concentrated means ≥60% of Alloy Processing's pounds in one chemical - here Nitric acid at 94.9%. Not a toxicity score.
