Gallium/Indium/Tin Alloy Pellets (Ga68.5/In21.5/Sn10) - 100mm W 100g

Gallium/Indium/Tin Alloy Pellets (Ga68.5/In21.5/Sn10) are eutectic alloys engineered for high thermal conductivity, fluidity, and surface wettability while maintaining a melting point well below room temperature. This composition blends gallium’s oxidation-resistant fluid metal properties, indium’s ductility, and tin’s structural reinforcement to produce a versatile, mercury-free liquid metal suitable for electronics cooling, flexible interconnects, and adaptive device architectures. Applications span thermal interface materials for high-performance computing, reconfigurable printed circuits, and precision sensing systems. Specific uses include Galinstan-based TIMs enhanced with copper flakes for improved thermal conductivity, nanorod forms for micro/nanorobotics, and oxide-modified films for thin-film transistors in optoelectronic devices. In research, the alloy’s tunable physical properties and multi-metal synergy enable novel applications in stretchable electronics, microfluidics, and energy-efficient cooling solutions, making it a valuable material in both industrial and scientific innovation.
