· Cu8Ni7Sn5

Cu8Ni7Sn5 is a copper-nickel-tin ternary alloy that belongs to the family of copper-based engineering alloys, likely formulated to balance strength, corrosion resistance, and workability. This composition sits within the space of cupronickel and bronze alloys traditionally used in marine and corrosion-critical environments, with the nickel addition enhancing resistance to seawater and the tin providing solid-solution strengthening. Engineers would select this alloy when standard brasses or simple bronzes are insufficient, particularly in applications demanding both mechanical reliability and long-term durability in harsh or immersion conditions.

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.
