Various materials. 

1) Aluminium shell or pipe, it is cheaper, but not good in resistance to corrosion. 

2) Brass or copper shell or pipe, it is good in resistance to corrosion. But it costs higher. 

3) Ceramic shell, it’s good in resistance to corrosion. But its heating power could not be very large. 

4) Stainless steel or titanium shell or pipe, it is very excellence for preventing corrosion, and meets food safe standard. But it costs higher and has bigger bulk. China patent number: ZL 2011 2022 0811.4, ZL 2011 2022 0805.9.

5) Anti-corrosion coated aluminum shell, it is corrosion resistance, and prevent incrustant, but the cost is quite high.

Using higher switch temperature PTC can get higher power, 220~270℃switch temperature PTC is selected usually. But if select too high switch temperature, the reliable will reduce. 

Power is almost same to change the voltage twice or decrease of 1/2.
