LT15 — The Alloy That Redefines Thermal Performance.
Developed entirely in-house by NEDEC's R&D team, LT15 outperforms every major die-casting alloy across thermal conductivity, corrosion resistance, and elongation — simultaneously.
Thermal Conductivity
A383: 96 W/m·K (+97%)
Better heat dissipation for EV power electronics
Corrosion Resistance
A383: Rating 2/5
Zero weight gain after 72h salt spray test
Elongation
A383: 3.5% (3x higher)
Superior formability — fewer cracks under stress

R&D Development Story
As BEV inverters and ECUs demand increasingly higher thermal performance, standard die-casting alloys began reaching their physical limits. NEDEC's R&D team invested years of material science research to develop LT15 — an alloy that exceeds the thermal requirements of next-generation EV components without sacrificing castability or corrosion resistance.
