Introduction
Material property differences directly determine shaped wire drawing machine model, die material, lubrication system and drawing pass design. Improper material-equipment matching causes persistent wire breakage, severe die wear and unqualified surface quality. This guide systematically analyzes 5 mainstream metal materials processed by Sky Bluer shaped wire drawing equipment, providing targeted process solutions for each grade of alloy.
Copper & Copper Alloy Shaped Wire Drawing
Applicable Grades: C10200 oxygen-free copper, C11000 electrolytic copper, brass C36000, bronze C52100
Product Applications
EV motor magnet flat wire, transformer conductive profiles, electronic terminal square wire, photovoltaic busbar
Recommended Machine Configuration
- Process: Wet shaped wire drawing (excellent cooling prevents copper adhesion on dies)
- Die material: PCD polycrystalline diamond (mirror surface, ultra-long service life for soft copper)
- Lubricant: Water-soluble synthetic cooling emulsion
Key Processing Challenges & Solutions
Copper is extremely ductile and prone to galling metal transfer on die inner walls. Solution: Continuous emulsion filtration + polished PCD finishing dies, control single-pass area reduction below 20%. For ultra-fine copper profiles below 0.3mm, adopt low-tension closed-loop servo drawing hosts.
Stainless Steel Shaped Wire Drawing
Applicable Grades: 304, 316L, 302 spring stainless, 17-4 PH precipitation hardening stainless
Product Applications
Medical guide wire profiles, automotive suspension spring wire, food machinery special wire, aerospace fastener profiles
Recommended Machine Configuration
- Process: Medium dry shaped drawing machine with powder soap lubrication
- Die material: High-hardness tungsten carbide (resists stainless abrasive grain wear)
- Lubricant: High-temperature drawing soap powder with anti-stripping additives
Processing Pain Points
Stainless steel has strong work hardening effect; multi-pass drawing requires inline annealing between forming stages to restore ductility. Our dedicated stainless steel shaped lines integrate continuous bright annealing furnaces to eliminate cold stress.
Carbon Steel Shaped Wire Drawing
Applicable Grades: Low-carbon mild steel, medium carbon steel, high carbon spring steel SAE1070/1095
Product Applications
Construction fastener square wire, agricultural machinery spring profiles, wire mesh special shaped blanks
Recommended Machine Configuration
- Process: Heavy-duty dry shaped drawing equipment with high-torque capstan blocks
- Die material: Reinforced tungsten carbide with thick bearing land
- Lubricant: Lime-based dry lubricant powder for high-strength steel deformation
Technical Notes
High-carbon steel easily cracks under excessive single-pass reduction; split forming into 6–8 progressive die passes, strictly control drawing speed below 25m/min to avoid thermal microcracks.
Titanium & Titanium Alloy Shaped Wire Drawing
Applicable Grades: Gr1 pure titanium, Gr2 industrial titanium, TC4 Ti-6Al-4V aerospace alloy
Product Applications
Medical implant profiles, lightweight aerospace structural wire, corrosion-resistant chemical equipment shaped wire
Custom Machine Configuration (Sky Bluer Exclusive Titanium Line)
- Process: Semi-wet drawing with high-temperature anti-oxidation specialized lubricant
- Die material: Nano-coated tungsten carbide to prevent titanium alloy adhesion
- Supporting system: Integrated vacuum bright annealing unit after drawing
Unique Processing Difficulties
Titanium reacts with oxygen under high drawing heat, forming hard oxide scales that scratch profile surfaces. Our titanium drawing machines add sealed nitrogen protection chambers between die stations to isolate air contact during forming. Full titanium lubrication system details are covered in our industry technical blog on the website homepage.
Alloy Wire (Nickel, Invar, Kovar) Shaped Drawing
Nickel-iron low-expansion alloy, resistance alloy shaped wire for precision instrument components
Matching Machine Tips
Combine dry pre-forming + wet finishing two-stage drawing; use customized low-friction die surface coating to reduce alloy metal sticking.

Cross-Material Production Line Upgrade Advice
Factories processing multiple metal materials can purchase modular shaped wire drawing machines with interchangeable dry/wet lubrication boxes and quick-change die cassettes, avoiding purchasing separate standalone machines for each alloy type—refer to our buying selection article for modular equipment budget calculation.
