Key Types & Functional Benefits
1) Aluminum Wire Drawing Fluids
| Type | Function & Benefits |
|---|---|
| Semi-Synthetic Emulsions | For medium/coarse aluminum wires (EC-Al and alloys). Excellent lubrication & cooling with clean surfaces suitable for enamel-wire production. |
| Hot Rolling Fluids | Designed for aluminum rod hot milling; maintain emulsion stability and heat transfer at elevated temperatures. |
| Annealing Fluids | Protect aluminum rods during controlled cooling at 400–450 °C; oxidation control, minimal distortion, bright surfaces. |
| Neat Drawing Oils | Low-viscosity, high-film-strength oils with EP/AW packages for fine and ultra-fine Al wire; low residue, high die life, excellent surface for downstream coating. |
2) Copper, Brass & Tin Wire Drawing Fluids
| Type | Function & Applications |
|---|---|
| Full Synthetic Fluids | Water-miscible, stain-free for fine/coarse drawing of copper, brass, and plated wires (tin, silver, nickel); ideal for multi-wire, high-speed machines. |
| Mineral-Based Emulsions | High-ratio base oils with robust emulsifiers, defoamers, and biocides; for rod breakdown and medium/fine drawing. Long emulsion life and clean operation. |
3) Copper Annealing & Post-Processing Fluids
| Type | Role in Processing |
|---|---|
| Annealing Fluids | Water-miscible coolants for copper/tinned wires; provide heat removal, bright surfaces, and oxidation resistance during annealing. |
| Post-Casting/Rolling Coatings | Applied after casting/rolling (e.g., Outokumpu, Rautomead lines) to prevent oxidation/staining in atmosphere; optionally dosed into drawing emulsions at 0.4–0.6%. |
4) Iron, Steel & Ferrous Metal Drawing Fluids
- Water-miscible drawing fluids for iron/steel wire, rod, and sheet drawing.
- Stable emulsions with advanced lubrication and cooling for high-speed operations.
- Excellent in welding-wire skin-pass to achieve consistently low-friction finishes.
Key Performance Attributes
| Attribute | Benefits |
|---|---|
| Water-Miscibility & Emulsion Stability | Easy dilution in soft/hard water; extended fluid and emulsion life. |
| High Lubricity | Lower die wear, longer tool life, supports higher draw speeds. |
| Superior Cooling | Prevents overheating of dies, capstans, and wire surfaces. |
| Corrosion & Oxidation Protection | Keeps metal bright; mitigates rust and discoloration during/after processing. |
| Microbial & Foam Resistance | Hygienic systems, stable emulsions, no foam overflow at high line speeds. |
| Clean Wire Surfaces | Essential for enamel wire, electrical conductors, and premium appearance. |
| Material Versatility | Optimized options for both non-ferrous and ferrous materials. |
