The microstructure is therefore rather a metal matrix composite than a true alloy.The alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.</p> </div> </div> <div class="toggle faq faq-marketplace faq-authors"> <div class="togglet"><i class="toggle-closed icon-angle-down"></i><i class="toggle-open icon-angle-up"></i>Tungsten Copper Properties?</div> <div class="togglec"> <p><img src="pic/Tungsten-Copper-Bars.jpg" alt="tungsten copper bar" title="tungsten copper bar" /></p> <p>Copper tungsten alloys are a used in a wide variety of applications including heat sinks in electrical devices, resistance welding, electrical contacts and machining where the alloy is used as an arc contact. The alloy properties are dependent on the mixture of the copper and tungsten alloy. Typically, higher levels of copper are used in jobs in which thermal and electrical conductivity is more critical and higher levels of tungsten are used when strength and hardness are needed.</p> </div> </div> <div class="toggle faq faq-marketplace faq-authors"> <div class="togglet"><i class="toggle-closed icon-angle-down"></i><i class="toggle-open icon-angle-up"></i>Tungsten Copper Machining?</div> <div class="togglec"> <p><img src="pic/what-is-tungsten-copper-plate-1.JPG" alt="tungsten copper bar" title="tungsten copper bar" /></p> <p>The melting point of tungsten, copper vary greatly higher than the boiling point of the copper melting point of tungsten and tungsten copper immiscible, the general method of smelting is difficult to produce tungsten copper alloy, the only powder metallurgy to make tungsten copper composites manufacturing to become a reality.
