At 70% it is the standard concentrated strength for passivation tanks, pickling and bright-dip baths, and nitration and dissolution steps in chemical manufacturing. It is a powerful oxidizer that dissolves most common metals and strips oxide scale, which is why plating shops, fabricators, and chemical processors keep it on hand.\u003c\/p\u003e\u003cp\u003eAs an industrial chemical distributor, Alliance Chemical supplies this concentrated nitric acid to fabrication shops, plating and finishing lines, and chemical manufacturers. Explore our full range of acids in our \u003ca href=\"\/collections\/acids\"\u003eacids collection\u003c\/a\u003e. This product is used for surface preparation, metal dissolution, and chemical synthesis where oxidizing strength and consistent concentration are what the process depends on. Our Nitric Acid 70% Technical Grade is packaged and handled in compatible containers to maintain its concentration from our warehouse in Taylor, TX to your facility.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eTechnical grade is the industrial tier of nitric acid: a 70% solution supplied for work where oxidizing strength and consistent concentration matter, but certified limits on trace impurities such as iron or chloride are not written into the process. Stainless steel passivation, pickling and descaling of steel, brightening and etching of brass and copper, dissolving metals and ores in industrial recovery and refining, and serving as a nitrating agent or intermediate in chemical manufacturing all run on this grade, and it is the cost-effective choice for them. Our \u003ca href=\"\/pages\/industries\/electronics\"\u003eelectronics industry solutions\u003c\/a\u003e page lists the acids we supply to that sector.\u003c\/p\u003e\u003cp\u003eThe 70% concentration is the standard concentrated strength of nitric acid and provides the oxidizing activity needed for controlled passivation and dissolution. A weaker or inconsistent solution can leave passivation incomplete and stainless steel vulnerable to premature corrosion. Our 70% Technical Grade is not supplied as ACS, reagent, or laboratory grade, and it does not carry a low-particle or trace-metal specification. If your protocol names one of those tiers, or your downstream analysis depends on certified trace-impurity limits, specify that grade when you order. A lot-specific Certificate of Analysis is available on request.\u003c\/p\u003e\n\u003cdiv class=\"chemical-profile\" data-source=\"canonical\"\u003e\n\u003ch3\u003eChemical Profile\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003eCAS Number\u003c\/dt\u003e\n\u003cdd\u003e7697-37-2\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eHNO3\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e63.013 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003e181 °F at 760 mmHg (NIOSH, 2024)\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e-44 °F (NIOSH, 2024)\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.5 at 77 °F (NIOSH, 2024) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003eNitric acid, other than red fuming appears as a pale yellow to reddish brown liquid with reddish brown vapors and a suffocating odor.

Nitric Acid 70% must be stored in cool, dry, well-ventilated facilities, ideally within a temperature range of 50°F to 80°F, away from direct sunlight. Container compatibility is crucial; the chemical must be kept in its original fluoropolymer, glass, or specially treated stainless steel containers. It is highly incompatible with organic materials, combustible substances, strong bases, active metals, and reducing agents, as contact can lead to violent, exothermic reactions or the evolution of hazardous nitrogen oxides.\u003c\/p\u003e\u003ch3\u003eOrder \u0026amp; Documentation\u003c\/h3\u003e\u003cp\u003eAt Alliance Chemical, we ensure full transparency and compliance for all chemical shipments.
