Electrical Steel

¢¹ Commercial

This is used for slight forming such as as-falt roll forming or bending and available Pure-Zn, Zn-Fe, Zn-Ni and Terne.

¢º Pure-Zn : This is widely used for inner or outer panel of automobiles, home appliances and construction materials. Oiling treatment generally is applied for automobile use and phosphate and anti-fingerprint treatment is supplied for home appliances use according to customer's requirements.

¢ºZn-Fe : This shows good paintability and corrosion resistance after painting. It is suitable for automobile outer panels and both-side coating is applied for inner panels.

¢º Zn-Ni : This shows good weldability corrosion resistance and paintability and is perferred to inner or outer panels of automobiles.

¢º Terne : This shows excellent gasoline resistance and solderability, and is used for fuel tanks of automobiles and heating appliances.
