Tungsten copper electrodes are commonly used in ignition systems, especially in applications where high temperature, wear resistance and reliable electrical conductivity are critical. Some specific applications of tungsten copper electrodes for ignition include:

1. Spark plug: Tungsten copper electrode is used to make spark plugs for internal combustion engines. Tungsten copper's high melting point and excellent electrical conductivity make it ideal for producing a consistent and reliable spark in the combustion chamber.

2. Gas igniter: In industrial and household gas appliances, gas igniters use tungsten copper electrodes to generate sparks to ignite gaseous fuel. The durability and wear resistance of tungsten copper make it suitable for long-term reliable operation in these applications.

3. Aerospace ignition systems: Tungsten copper electrodes are used in ignition systems for aerospace applications, where high temperature resistance and reliable spark generation are critical to the operation of aircraft engines and propulsion systems.

In these applications, the use of tungsten-copper electrodes helps ensure consistent and reliable spark generation, contributing to the efficient and safe operation of various ignition systems.
