· Ni2Mn0.25Ti0.75Sn

Ni₂Mn₀.₂₅Ti₀.₇₅Sn is a Heusler-type intermetallic alloy based on the nickel–manganese–tin family, modified with titanium substitution on the manganese site. This composition belongs to the shape-memory alloy (SMA) research family, where partial titanium doping of the Mn–Sn sublattice is used to tune martensitic transformation temperatures and magnetic properties for enhanced functional performance. The material is primarily investigated in academic and early-stage development contexts for applications requiring simultaneous shape-memory and magnetic response, particularly where controlled transition temperatures and two-way actuation are beneficial.

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.
