Cr20Ni80 Cold-Drawing alloy wire
 
 
 
Such alloys with stable physical properties, good mechanical properties, fine welding .It won't break when it was used for a long time. They are used in the manufacture of household appliances and the heating elements below 1000 ℃, long life. Due to the high volume of nickel, the price is higher than others.
