King Tiger Z508 — Nickel-Copper Cast Iron Electrode (AWS A5.15 ENiCu)

HAKUDO Z508 is a nickel-copper (Monel-type) electrode for the hardest cast-iron repairs — oil-soaked, contaminated, or high-carbon-equivalent iron where other rods crack. Best crack resistance in the cast-iron range.

Best for: oil-impregnated castings, large diesel blocks, high P/S irons, difficult or previously-failed repairs, precision machine bases.

Properties

• Tensile strength (Rm) ≥ 380 MPa
• Hardness HB 160–200 · low crack sensitivity
• Core: Ni-Cu (Monel system)
