· JVASP-7862· Sr2CrO4

Strontium chromate (Sr₂CrO₄) is an inorganic ceramic compound belonging to the chromate family, characterized by a dense crystalline structure. This material is primarily used as a corrosion inhibitor and pigment in protective coatings, particularly in aerospace and defense applications where long-term corrosion resistance is critical. Sr₂CrO₄ is notable for its effectiveness in chromate conversion coatings on aluminum and steel substrates, though environmental and health concerns surrounding hexavalent chromium have driven industry research toward alternative inhibitor systems in recent years.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
