TIG7835L — Product overview
TIG®7835L is a gallium-alloy liquid-metal thermal interface compound that achieves a liquid state and low surface tension at room temperature through advanced alloying, without requiring heating to a separate melting point. It combines high fluidity with very high thermal conductivity (35 W/m·K) and is resistant to evaporation and leakage, with stable physical and chemical properties for long-term operation. As an underlying technology for high-power heat dissipation, TIG®7835L is well suited to demanding cooling needs that exceed the capability of traditional silicone grease. Note that the alloy is electrically conductive (resistivity <10⁻⁴ Ω·m) and can short-circuit adjacent traces or pads if it spreads, and it corrodes aluminum on direct contact, so installation must contain the metal within the bond line.
