Electrolytic nickel rod

[ Supply status ]
Fully annealed soft state, without interlayer, crack and oxidized impurity, bright bar surface is smooth, with high dimensional accuracy.

[ Processing Technology ]

Smelting ingot of electrolytic nickel plate → hot rolling and forging open billet → cold drawing and fine drawing → vacuum annealing and stress removal → straightening and polishing → flaw detection, slitting and warehousing.

[ Material Performance ]

Nickel has high purity, stable passive anticorrosive coating under concentrated alkali, hydrofluoric acid and salt mist environment, and is resistant to alkali embrittlement; Excellent conductivity and thermal conductivity, suitable for electroplating conductive members; Good plasticity, bending, turning and milling, argon arc welding are not easy to crack; Strong chemical stability under high temperature conditions, few impurities dissolved, guarantee electrolyte and high-purity material purity, and non-magnetic, suitable for precision equipment.

[ Process structure ]

High-purity electrolytic nickel plate is used as raw material, with strict impurity control and uniform ingot composition without segregation; The grain is refined by multiple hot rolling to eliminate internal loose pores; Vacuum annealing is used to remove the processing stress, and the finishing is not easy to deform; The surface of the cold drawn rod shall be free of sand holes and pits, and each batch shall be subject to spectrum re-inspection, ultrasonic flaw detection for large-diameter bars, and internal microdefects shall be removed.
