Application:

1. Wire and cable industry (core application)

Oxygen-free copper rod (OFHC):

Used to manufacture electrical copper wire (such as enameled wire, power cable, communication cable), requiring high conductivity (≥101% IACS) and low oxygen content (≤10ppm).

The copper rod produced by the updrawing method can be directly made into fine copper wire through the subsequent wire drawing process.

Low-oxygen copper rod:

Suitable for scenarios with slightly lower conductivity requirements but cost sensitivity (such as building wiring).

2. Electronic and electrical industry

High-precision copper alloy rod:

Such as tin-phosphor bronze (C5191, C5210) is used for connectors, terminals, relays and other electronic components.

Copper-nickel alloy (white copper) is used for resistors and thermocouple compensation wires.

Special-shaped copper materials:

Produce square, hexagonal and other cross-section profiles through customized crystallizers for radiators, conductive bars, etc.

3. Hardware and bathroom industry

Copper rod/tube blank:

Processed into faucet valve cores and bathroom accessories (corrosion-resistant and antibacterial).

Brass (H59, H62) is used for locks, gears, and decorative parts.

Hollow pipes:

Some upward-pulling units can produce thin-walled tube blanks for refrigeration pipelines, capillaries, etc.

4. New energy and high-end manufacturing

Photovoltaic and lithium battery copper materials:

Ultra-fine copper wire for photovoltaic welding strips, high-purity copper strip blanks for lithium battery tabs.

Special alloys:

For example, copper-chromium alloy (CuCr) is used for vacuum switch contacts, and copper-iron alloy (CuFe) is used for magnetic components.

5. Other applications

Art casting:

Copper rods for copper sculptures and handicrafts.

Industrial accessories:

Wear-resistant copper alloy parts such as bearing bushings and valve components.

Product Features:

1. Short process and efficient production

Integrated molding:

Smelting → casting → molding is completed continuously, eliminating multiple processes such as traditional hot rolling and forging, shortening the production cycle.

Quick cooling:

The water-cooled crystallizer realizes rapid solidification of molten metal, grain refinement, and high production efficiency (such as the production speed of copper rods can reach 10~20 meters/minute).

2. Energy saving and environmental protection

Low energy consumption:

Directly cast from molten metal, it saves 30%~50% energy compared with traditional rolling process.

Low oxidation loss:

Closed smelting (with protective gas or charcoal covering), copper liquid oxidation rate <0.5%, and the yield rate is as high as 98% or more.

Emission reduction:

No high-temperature rolling link, reducing smoke and exhaust gas emissions.

3. High purity and high performance of products

Ultra-low oxygen content:

The oxygen content of oxygen-free copper rod is ≤10ppm (national standard TU1 level), and the conductivity is ≥101% IACS, which is suitable for high-end wires and cables.

Dense structure:

Rapid cooling inhibits grain coarsening, reduces pores and inclusions, and improves mechanical properties (such as tensile strength and ductility).

4. Flexible and diverse product specifications

Multi-shape adaptation:

By replacing the crystallizer, round rods, flat billets, square bars, hexagonal bars and other special-shaped materials (usually Φ8~50mm in diameter) can be produced.

Multi-alloy compatibility:

In addition to pure copper, brass (H62, H65), bronze (tin phosphor bronze), nickel silver (BFe10-1-1) and other alloys can be produced.

5. Small batch customization advantage

Low-cost switching:

Suitable for small batch and multi-variety production (such as special alloys or non-standard sizes), flexible equipment adjustment.

High-precision control:

The automated system adjusts the temperature and traction speed in real time to ensure tolerance accuracy (such as copper rod diameter tolerance ±0.1mm).

6. Compact equipment and low maintenance

Small footprint:

Compared with horizontal continuous casting or rolling production lines, the equipment has a compact structure and is suitable for small and medium-sized enterprises.

Long crystallizer life: Made of high thermal conductivity copper alloy, it is easy to maintain and has low replacement cost.
