‌Zinc-nickel-copper rod‌ is an alloy composed of copper, nickel and zinc, with a silvery-white appearance and excellent mechanical properties. The main components of zinc-nickel-copper rod include copper, nickel, zinc and other elements.
With its superior surface finish and consistent dimensions, DETONG's White Copper Rod is well-suited for manufacturing precise parts for industries such as electronics, telecommunications, and instrumentation. DETONG ensures high-quality production and delivery of this versatile copper rod to meet global standards.

Chemical properties
Corrosion resistance

White copper exhibits excellent corrosion resistance in seawater, acidic environments and alkaline solutions, especially in marine environments. Its resistance to chloride ion corrosion is outstanding, which is better than ordinary copper alloys.

Adding manganese (Mn) or iron (Fe) can further enhance its seawater corrosion resistance.

Antioxidation

In high temperature and humid environments, a dense oxide film can be formed on the surface of white copper to slow down further oxidation.

Thermal stability

High nickel white copper (such as B30 containing 30% nickel) can still maintain stable chemical properties at high temperatures and is suitable for high temperature environments.

Anti-biological fouling

It has an inhibitory effect on the attachment of marine organisms (such as algae and shellfish) and is suitable for ship components.

Reaction with acid and alkali

Resistant to dilute sulfuric acid, hydrochloric acid and organic acids, but corrodes faster in strong oxidizing acids (such as concentrated nitric acid).

Main uses
Marine engineering

Condenser, seawater pipes: widely used in shipbuilding and offshore platforms due to their resistance to seawater corrosion.

Ship accessories: such as pump valves, propeller shafts.

Electronic appliances

Precision resistors: such as manganese copper (Cu-Ni-Mn alloy) is used for high-precision resistors.

Connectors, terminals: take advantage of their conductivity and corrosion resistance.

Currency and decoration

Coins: Coins in some countries use white copper (such as alloys containing 25% nickel).

Jewelry, watch cases: imitate silver appearance and are not easy to change color.

Heat exchanger

Heat exchange tubes in power plants and petrochemical industries, resistant to high-temperature steam and corrosive media.

Other fields

Medical equipment: Some surgical instruments take advantage of their antibacterial properties.

Shape: Hexagonal/round/square
Specifications (mm): Customizable
Transport packaging: Standard export carton/pallet/crate, etc.
