I am not an authority on the subject of the physics of X-ray tubes, but I will attempt to explain what little I know about the subject. The type of target material in an X-ray tube mostly determines the energy peaks that are called "Characteristic Radiation". Tungsten, for example, has a Characteristic radiation peak at around 70KeV. It also has some low-energy minor peaks at around 10KeV, but the majority of radiation in an X-ray beam comes from Bremmstralung radiation, which is broad-spectrum. So changing the target material will alter the characteristic radiation peaks in the spectrum, which could be helpful or detrimental depending on your application.
If any knowledgeable person out there who understands this better than I do could add to this discussion or correct what I have said, please do!
