production description:
Nickel hascription: high chemical stability and good corrosion resistance in many media. Its standard electrode position is -0.25V, which is positive than iron and negative than copper.Nickel exhibits good corrosion resistance in the absence of dissolved oxygen in dilute non-oxidized properties (e.g., HCU, H2SO4), especially in neutral and alkaline solutions.This is because nickel has the ability to passivate, forming a dense protective film on the surface, which prevents nickel from further oxidation.
Application:
It could be used to make electric heating element in low-voltage apparatus, such as thermal overload relay, low-voltage circuit breaker, and so on.And used in heat exchanger or condenser tubes in evaporators of desalination plants, process industry plants, air cooling zones of thermal power plants, high-pressure feed water heaters, and sea water piping in ships.
