Silver thermal compounds may have a conductivity of 3 to 8 W/(m·K) or more, and consist of micronized silver particles suspended in a silicone/ceramic medium. However, metal-based thermal paste can be electrically conductive and capacitive; if some flows onto the circuits, it can lead to malfunction and damage.
Very high thermal conductivity measurements up to 22,600 w m −1 K −1 were reported by Fenton, E.W., Rogers, J.S. and Woods, S.D. in reference 570 on page 1458, 41, 2026–33, 1963. The data is listed on pages 6 through 8 and graphed on page 1 where Fenton and company are on curves 63 and 64.
Arctic Alumina is a ceramics-based polysynthetic thermal compound using aluminum oxide as a thermal transfer medium. It is a lower-cost product than Arctic Silver 5. [1] The 2009 BenchmarkReviews.com 80-product review rated Alumina in the Good class, with a B+ "enthusiast grade"; [2] it cooled a test system 10% better than the last-place finisher.
The thermal conductivity of a material is a measure of its ability to conduct heat.It is commonly denoted by , , or and is measured in W·m −1 ·K −1.. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal conductivity.
Silver is a chemical element; it has symbol Ag (from Latin argentum 'silver', derived from Proto-Indo-European *h₂erǵ ' shiny, white ') and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. [11]

A thermal interface material (shortened to TIM) is any material that is inserted between two components in order to enhance the thermal coupling between them [1].A common use is heat dissipation, in which the TIM is inserted between a heat-producing device (e.g. an integrated circuit) and a heat-dissipating device (e.g. a heat sink).
Its 7% silver content requires a higher temperature range, but yields superior strength and vibration resistance. [75] Sn 90 Au 10: 217 [76] Yes: Yes: Au 80 Sn 20: 280: Yes: Yes: Au80. Good wetting, high strength, low creep, high corrosion resistance, high thermal conductivity, high surface tension, zero wetting angle. Suitable for step soldering.
