the Nickle element content is 35% percent, it's the best material for electric heater, won't corrosion, have super anti-corrosion, dry-heat resistant, super heat conduction, etc feature.

Normal electric heater material is just SS304-2B(nickle is 9%) or cooper, it's not a good material for electric heater, easily corrosion.
So the heat conduction efficiency is very low. Should replaced it frequently.
