· Cu12Ni3Sn5

Cu12Ni3Sn5 is a copper-nickel-tin ternary alloy belonging to the family of copper-based engineering alloys, combining the corrosion resistance of nickel and the strengthening effects of tin in a copper matrix. This composition sits within the historical space of naval brasses and modern cupronickel alloys, though the specific ratio suggests potential application in wear-resistant or bearing contexts where tin acts as a hardening phase. The alloy family is valued in industries requiring corrosion resistance, thermal conductivity, and moderate strength, with particular relevance where seawater exposure or high-cycle wear resistance is critical.

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.
