I. Nickel Alloy N6 Chemical Composition (wt%):
Ni ≥ 99.5%, C ≤ 0.1%, Cu ≤ 0.1%, Si ≤ 0.1%, Mn ≤ 0.05%, Mg ≤ 0.1%, S ≤ 0.005%, P ≤ 0.002%, Fe ≤ 0.1%, Pb/Bi/As/Sb/Cd/Sn ≤ 0.002%, Zn ≤ 0.007%, Total Impurities ≤ 0.5%
II. Nickel Alloy N6 Processing Properties:
Cold Working: Cold rolling, cold drawing, stamping; precision strip and wire require intermediate annealing to remove hardening; control the amount of deformation per pass.
Hot Working: Temperature range 700-1200℃, hot rolling, forging. TIG welding or laser welding; inert gas protection; pre-weld oxide layer removal.
Machining: The material is relatively soft and sticky, easily causing tool sticking and chip removal difficulties. Sharp tools are required. Low speed, high feed rate, and adequate cooling are recommended.
