Why Leading Copper Drawing Units Choose CU-56
1. Zero Annealing Stains
Unlike low-grade soluble oils sold on marketplace portals that leave sticky carbon soot on copper wire during annealing, CU-56 decomposes cleanly leaving no trace on the conductor.
2. Extended Die Longevity
High extreme-pressure (EP) boundary lubrication film shields PCD (polycrystalline diamond) and tungsten carbide dies, cutting tooling replacements by up to 35%.
3. Bio-Stable Anti-Foam System
Formulated with advanced bio-resistant agents that prevent bacterial sump souring, foul odor, and excessive foam generation under high pump pressure.
Frequently Asked Questions: CU-56 Copper Drawing Oil
What machines are compatible with CU-56?
CU-56 is designed for high-speed continuous multi-die breakdown machines, tandem systems, and intermediate/fine copper drawing benches from brands like Niehoff, Henrich, Samp, as well as Indian manufactured wet wire drawing machines.
Can I get a Certificate of Analysis (COA) with each batch?
Yes. As the direct manufacturer in Sahibabad, Ghaziabad, every dispatched 200 KG drum consignment is accompanied by a batch-specific Certificate of Analysis verifying pH, viscosity, and copper corrosion performance.
How can I request a qualification sample?
