Chromic Acid Supplier — Hard Chrome Plating Grade CrO₃

What Is Chromic Acid?

Chromic Acid refers to the electrolyte solution formed when chromium trioxide (CrO₃) dissolves in water, producing H₂CrO₄. As a hexavalent chromium compound, it is listed on the EU REACH SVHC (Substances of Very High Concern) candidate list due to its carcinogenicity and is subject to strict regulatory controls in many jurisdictions. Terracore Chemicals supplies this product exclusively to verified industrial end-users with appropriate authorizations and handling documentation.

Hard Chrome Electroplating

Chromic Acid is the fundamental electrolyte in hard chrome (functional chrome) plating baths. Hard chrome deposits provide exceptional hardness, wear resistance, and low coefficient of friction on engineering components such as hydraulic cylinders, piston rods, rolls, and dies. The chrome layer extends component service life significantly in demanding mechanical applications.

Decorative Chrome and Anodizing

In decorative chrome plating, chromic acid baths produce bright, reflective chromium deposits over nickel undercoats on automotive trim, taps, and consumer hardware. In aluminum anodizing, chromic acid anodizing (Type I) produces thin, corrosion-resistant oxide layers with excellent paint adhesion, widely used in aerospace applications.

Regulatory Compliance and Supply Terms

Due to its SVHC status, supply of Chromic Acid is restricted to verified industrial end-users only. Buyers must provide end-user declarations and demonstrate compliant waste treatment infrastructure. Full SDS and regulatory documentation accompany each delivery. Enquire with your facility details, jurisdiction, and intended application for supply eligibility assessment.
