Product Overview
Alliance Chemical supplies Nitric Acid 65% Technical Grade for metal finishing, pickling, and industrial processing. This strong mineral acid, with the chemical formula HNO3 and molecular weight 63.013, is used across metal fabrication shops, plating and finishing lines, and chemical manufacturing. As a Texas chemical supplier, we manage this material under quality controls that maintain its stability and concentration from our warehouse in Taylor, TX to your dock. This product is designed strictly for industrial use.
Our Nitric Acid 65% Technical Grade is a clear, pale yellow to reddish brown liquid that displays strong oxidizing properties and a characteristic choking odor. It is fully miscible in water, so it dilutes readily to the working strengths used in pickling baths, passivation tanks, and brightening dips. Since this product is highly corrosive to both metals and organic tissue, handling requires strict adherence to safety protocols. We distribute this acid in multiple volume configurations, from one-liter bottles to bulk 55-gallon drums, to accommodate both small process lines and larger industrial procedures.

Why This Grade
Technical grade is the industrial tier of nitric acid: a 65% solution supplied for work where oxidizing strength and consistent concentration matter, but certified limits on trace impurities such as heavy metals, sulfates, and chlorides are not written into the process. Pickling and descaling steel, passivating stainless components, brightening brass and copper, dissolving metals and ores in industrial recovery and refining, and serving as an intermediate in fertilizer and chemical manufacturing all run on this grade, and it is the cost-effective choice for them. Our electronics industry solutions page lists the acids we supply to that sector.
The 65% concentration is a stable, easily handled strength for tank work and dilution. Lower concentrations may lack the oxidizing power some finishing steps need, while higher concentrations (such as fuming nitric acid) present severe safety risks and spontaneous decomposition challenges. Our 65% Technical Grade is not supplied as ACS, reagent, or laboratory grade. 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.

Industrial Applications
- Ore and Metal Dissolution: Used as a strong mineral acid to dissolve metals and ore concentrates in industrial refining and metal recovery operations.
- Brass and Copper Brightening: Diluted into bright-dip baths to strip tarnish and oxide from brass and copper parts ahead of plating or finishing.
- Metal Pickling and Passivation: Formulated to clean stainless steel alloys by removing oxide scales and establishing a corrosion-resistant passive chromium oxide layer.
- Chemical Synthesis Intermediate: Acts as a nitrating agent in the production of specialized organic compounds, dyes, and chemical intermediates.
- Regenerating Ion Exchange Resins: Applied to strip accumulated cations from cation-exchange resins in water purification systems, restoring system capacity.
Hazmat & Shipping
Nitric Acid 65% Technical Grade is classified as a hazardous material due to its strong corrosive and oxidizing properties. Under Department of Transportation guidelines, this product is designated as UN2031, Hazard Class 8, Packing Group II. The proper shipping name is Nitric acid, other than red fuming, with at least 65 percent, but not more than 70 percent nitric acid. This material carries the Signal Word Danger. Because it is a strong oxidizer, it can accelerate the combustion of surrounding materials, requiring isolated shipping configurations. All shipments are packaged and dispatched according to strict DOT regulations to guarantee safe arrival at your facility.
The safety of operational personnel is paramount when handling this substance. In accordance with the GHS classifications H314 (Causes severe skin burns and eye damage) and H330 (Fatal if inhaled), specific personal protective equipment (PPE) is mandatory. Handlers must wear chemical-resistant gloves, a full face shield, protective acid-resistant clothing, and work under a certified fume hood. If ventilation is insufficient, appropriate respiratory protection matching hazard code H330 must be utilized. Alliance Chemical provides a comprehensive Safety Data Sheet (SDS) provided with every order to assist your safety compliance officer in establishing safe handling protocols.
Handling & Storage
Safe storage of Nitric Acid 65% Technical Grade requires dedicated, cool, and dry facilities away from direct sunlight and heat sources, ideally maintained at temperatures between 50°F and 85°F. This acid is highly incompatible with organic compounds, flammable solvents, reducing agents, and active metals, as contact can prompt rapid, exothermic reactions. Storage containers must be made of compatible materials, such as glass, fluorinated polymers (PTFE), or specialized stainless steel alloys. Keep containers tightly sealed to prevent the accumulation of hazardous vapors, and store them within a secondary containment system to safely manage any potential leaks.
Order & Documentation
Alliance Chemical is dedicated to providing consistent chemical quality and transparent compliance documentation. We offer this acid in several sizes, from individual liters to large commercial drums, supporting both pilot studies and full-scale industrial lines. A Certificate of Analysis (COA) available upon request for every lot we ship, allowing you to confirm assay and specification before use.
