Material Options: Pure copper (C11000, C12200 or per request)
Surface Finish: Acid pickled by default, with optional treatment per customer request
Machining Tolerance: Up to ±0.01mm
Available Dimensions:
Width/Diameter: 1.5mm to 80mm
Length: Up to 1000mm
Processes: CNC turning, threading, slotting, hole drilling
Minimum Order: Flexible MOQs for different project scales
Turnaround Time: Normally 5 to 7 working days from confirmation
Clean Electrical Contact Surface: Acid pickling removes oxidation and residues for low-resistance performance
Stable Quality from China Factory: Over 20 years of experience in custom machining and export production
