King Tiger Z308 — Pure-Nickel Cast Iron Electrode (AWS A5.15 ENi-CI)

HAKUDO Z308 is a pure-nickel electrode for high-quality cast-iron repair where the weld must be machinable afterwards. Soft, low-hardness deposit (HB 140–180) that turns, mills and drills cleanly; excellent for precise restoration.

Best for: precision engine and machine-tool castings, pump and valve bodies, gearbox housings, dies and tables — anywhere the repair is machined after welding.

Properties

• Tensile strength (Rm) ≥ 350 MPa
• Hardness HB 140–180 — fully machinable
• Core: ≥ 97% pure nickel
