FEATURES & BENEFITS
Indium imparts it’s unique properties in many indium solder alloy compositions. Key properties are:
- High Thermal Conductivity: >80W/m-k (bulk material)
- High Ductility: Indium can absorb CTE mismatch between semiconductors & package lids/heat sinks
- Compliant: Indium fills gaps and will wet to metallic and non-metallic surfaces

Indium and indium alloys are the ultimate thermal managementmaterials, offering exceptional ductility and superior heat dissipation.These products are best when utilized in cases where the outgassingof thermal greases is problematic, the conductivity of thermal greasesis insufficient for the heat dissipation needed, or the interface materialneeds to also serve as a mechanical connection. These elementsand alloys are available in powder for fillers, foils¹, wire and customfabricated preforms.
