What are Electrical Solid Copper Contacts?
Electrical Solid Copper Contacts are single-piece copper contact components used to form conductive and switching interfaces in relay assemblies, low-voltage electrical equipment, and other electromechanical components. A solid copper construction eliminates a separate bonded contact layer and copper base, making the part geometry, material condition, contact dimensions, and forming process the primary engineering variables. Customized production is available from drawings, CAD files, samples, or specified material requirements for wholesale and OEM orders.

Manufacturing Process Flow of Round Head Metal Copper Rivet
Raw Material Inspection and Spectrometric Analysis
Incoming copper rods and wire coils undergo rigorous optical emission spectroscopy and eddy current testing to verify chemical composition purity and eliminate internal inclusions.
Precision Cold Heading and CNC Turning
High‑speed mechanical headers and multi‑axis CNC lathes shape the copper wire into exact head diameters, shank lengths, and specialized contact face geometries.
Deburring, Cleaning, and Surface Passivation
Components pass through ultrasonic cleaning lines and chemical passivation baths to remove residual drawing oils and prevent surface oxidation before packaging.
Final Quality Control and Dimensional Sorting
Automated optical sorting systems inspect 100% of production batches for diameter, height, concentricity, and surface defects before vacuum‑sealed export packaging.
