Classification of W wire material composition
1. Hard alloy tungsten wire
Hard alloy W wire is the most commonly used tungsten wire material for high-frequency furnaces. It has a low carbon content and excellent high temperature and oxidation corrosion resistance, and is suitable for high temperature heating.
2. Pure tungsten W wire
Pure tungsten tungsten wire has a high melting point and density, is corrosion-resistant, but is easily oxidized, so its application range is narrow and is generally only used in high-temperature vacuum environments.
3. Tungsten-rhenium alloy W wire
Tungsten-rhenium alloy tungsten wire is made of tungsten and rhenium in a certain proportion. It has excellent high temperature resistance and mechanical strength and can work stably at high temperatures.
4. Tungsten-copper alloy tungsten wire
Tungsten-copper alloy tungsten wire is widely used in electronic products and medical equipment and other fields. It has high thermal conductivity and corrosion resistance, and is relatively cheap.
