Shop-Floor Operational Guidance
Practical machine-setup recommendations from over three decades of on-site wire mill technical troubleshooting.
1. Copper Passivation & Anti-Staining Chemistry
Copper is chemically sensitive to sulfur and aggressive chlorides, which cause tarnish and dark stains. CU-56 incorporates active non-ferrous corrosion passivators that maintain a bright mirror surface across raw and drawn wire.
2. Controlling Sump Temperature in Rod Breakdown
Heavy copper rod breakdown generates massive frictional heat. For optimum lubricity and emulsion life, maintain drawing oil temperature between 35°C and 45°C using plate heat exchangers or cooling towers.
3. Copper Fines & Sludge Management
Sub-micron copper dust suspended in emulsion turns standard oils into abrasive grinding fluid. CU-56 accelerates gravity settling in return pits and functions smoothly with inline centrifugation or hydrocyclone units.
4. Inline Annealing & Conductor Surface Purity
Drawn copper wire undergoes high-speed inline resistance annealing. Low-grade oils burn into conductive black soot that causes insulation breakdown in cable extrusion. CU-56 evaporates cleanly without residue.

Frequently Asked Questions
help_outline What is the recommended dilution ratio for CU-56 copper drawing oil in rod breakdown?
For continuous heavy copper rod breakdown (reducing 8.0 mm rod down to 1.2 mm - 1.6 mm wire), maintain an emulsion concentration of 8% to 12% in demineralized or softened water, monitored using a refractometer.
help_outline Does CU-56 copper drawing oil leave carbon spots after furnace annealing?
No. CU-56 is formulated with clean-evaporating synthetic esters that burn off completely without leaving carbon spots, ensuring immaculate bright conductors for cable extrusion and enameling.
help_outline Can CU-56 be used for multi-wire fine copper drawing machines?
Yes. For multi-wire fine drawing machines (drawing down to 0.15mm - 0.40mm), CU-56 operates at a lower concentration of 3% to 5% with exceptional lubricity and PCD diamond die protection.
help_outline What is the minimum order quantity (MOQ) and packaging standard?
Supplied in standard 200 KG sealed industrial steel drums. Commercial MOQ is 1 drum. Pilot sample cans are available for laboratory or bench evaluation upon contacting our Ghaziabad dispatch desk.
