· Cu6Ni9Sn5

Cu6Ni9Sn5 is a copper-nickel-tin ternary alloy that belongs to the cupronickel family, a group of corrosion-resistant copper-based materials commonly used in marine and aqueous environments. This specific composition combines the corrosion resistance of cupronickel with the strengthening effect of tin, making it suitable for applications requiring both durability in harsh conditions and moderate mechanical strength. The alloy is typically employed in marine engineering, heat exchanger tubing, and coastal infrastructure where resistance to seawater corrosion and biofouling 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.
