· Cu0.25Ni1.75MnSn

Cu0.25Ni1.75MnSn is a quaternary copper-nickel-manganese-tin alloy belonging to the family of shape memory alloys (SMAs) and/or high-strength nonferrous alloys. This composition sits within research and development territory for advanced functional alloys, likely investigated for its potential to combine moderate copper content with nickel-manganese base characteristics that are known to exhibit martensitic transformation behavior. The material is of interest where cost-effective alternatives to traditional copper-beryllium or nickel-titanium alloys are sought, particularly in applications requiring a balance of mechanical strength, corrosion resistance, and potential shape memory or damping properties.

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.
