Thermal conductivity - Import export

Copper alloys exhibit very high electrical and thermal conductivities, offering twice the conductivity of aluminum and thirty times the conductivity of stainless steel. Other advantageous characteristics include outstanding strength (notably copper beryllium alloys) and corrosion resistance as well as antimicrobial properties. Copper is most commonly used in electrical and electronic applications.

Unalloyed Tantalum is supplied to ASTM F560 – R05200 composition limits. Tantalum is selected for its corrosion resistance, thermal conductivity, high melting point, and ability to form a dielectric oxide film. Tantalum is very ductile and can be readily cold formed due to a low work hardening rate. Welding can be accomplished via resistance, TIG, or electron beam methods, with care taken to protect the weld and heat affected zone from air during welding. Because of the potential for hydrogen embrittlement, Tantalum can not be used for extended service in air or other oxidizing atmospheres above 260°C unless a protective inert atmosphere or vacuum is provided. Available Sizes: Tantalum is available from Hamilton Precision Metals as strip product from 0.0005” to 0.035” (0.0127 mm to 0.889 mm) in widths up to 12.0” (304.8 mm). The material conforms to UNS R05200 and meets the requirements of ASTM F560 and ASTM B708.

Cu-Ni 715 is a copper-nickel alloy that is resistant to corrosion in sea water. The alloy has good fatigue strength and relatively high thermal conductivity. This alloy is used mainly for flexible metal foil heaters. The alloy is readily formed in the annealed temper, and can be joined by the standard welding, brazing and soldering processes. Available Sizes: Cu-Ni 715 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.010” (0.0127 mm to 0.254 mm) in widths up to 12” (304.8 mm). The material conforms to ASTM B122 and UNS C71500.

They are especially designed for quick adaptation in molds or surfaces where the use of rivets either causes problems or impossibility to use. Cuadrawatt cartridges are the better choice. Cartridges with a low density of watts are most recommended for moderate heating up to a maximum temperatures of 300ºC. The square tube is made of prime quality stainless steel. All the tubes are perfectly calibrated both inside and outside, into which a long-life ceramic piece is inserted. The tube resists a continuous temperature variation and has the best possible thermal conductivity, as the ceramic piece is in contact with the wall of the tube, which makes the most perfect heat distribution possible.
