BFe30-1-1 Iron White Copper Bar Standard GB/T 4423-1992

Supply of High-Quality Free-Cutting BFe30-1-1 Iron White Copper Bars, Highly Corrosion-Resistant Iron-Nickel White Copper Material, Factory Direct Sales

Material Name: Iron White Copper Drawn Bar (Hard, 16–50mm)

Grade: BFe30-1-1

Standard: GB/T 4423-1992

● Characteristics and Application Range:

BFe30-1-1 iron white copper is a structural copper-nickel alloy with good mechanical properties and high corrosion resistance in seawater, freshwater, and steam, but its machinability is relatively poor. BFe30-1-1 iron white copper is used in the shipbuilding industry for condensers and thermostats operating under high temperature, high pressure, and high-speed conditions.
