90W10Cu Tungsten Copper Properties

90W10Cu tungsten copper properties are:

At 950 ℃ high speed pressing attainable relative density greater than 80.65% of W skeleton, by infiltration get 90W10Cu composites.

At room temperature, 600 ℃, 950 ℃ for high-speed tungsten preform pressing, pressing as the temperature rises, the green density increases.

High velocity compaction, powder mass increases, due to the ability of additional density decreases, resulting green density decreases. With the increase in the number of high-speed pressing, green density is improved.

Using high-speed pressing technology combined with infiltration of 90W10Cu preparation material and the thermal expansion coefficient and other indicators have reached the requirements of the appropriate heat sink material.

90W10Cu Tungsten Copper Production Technology

90W10Cu tungsten copper alloy mainly used to suppress the high-speed production technology to prepare, and then in 1400 ℃ high temperature hydrogen furnace infiltrated get 90W-10Cu composite. Research repression affect the quality of the pyrometer compacts green density and microstructure of. The results of surface, with the suppression of the temperature rise, the compact density, high-speed suppression obtained at 950 ℃ relative density greater than 80.65% of W skeleton dense tungsten particles connection, distribution, pore connectivity is good. Compacts increases quality, due to the applied energy density is reduced, leading to the green density decreases. By twice the height of repression, the green density further increases; the relative density of 99.5% 90W10Cu materials, thermal conductivity 175W / (mK), tungsten copper alloy 90W10Cu indicators have reached the requirements of the appropriate heat sink material.

Tungsten Copper Spring Contacts

Tungsten Copper Spring Contacts Picture

Tungsten copper spring contacts with excellent resistance arc burning and welding resistance, breaking arc performance, good thermal conductivity, thermal expansion, high temperature does not soften, high strength, high density, high hardness and other characteristics. It has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At a temperature above 3000 ℃, copper alloy is liquefied evaporated absorbs heat, reduces surface temperature, so these materials are also referred to as metal materials sweating.

Tungsten copper spring contacts are made by powder metallurgy method high pressure contacts of different shapes. Is the use of high-purity tungsten copper contact of tungsten metal powder excellent characteristics and plasticity, high conductivity copper powder of high purity, etc., by isocratic pressing, high temperature sintering, melting refined copper infiltration process of composite materials.

Tungsten copper spring contacts are widely used as high pressure, ultra-hydraulic switch contacts and circuit breakers, protection ring for electric upsetting anvil block material, conductive Tsui automatic submerged arc welding, plasma cutting machine nozzles, welding, welding of welding head, seam welding wheels, electrodes and spark electrode sealing gas Mao point, spot welding, butt welding materials.
