Copper Stamped Parts for the USA Market

Copper Stamped Parts manufactured by Conex Metals are engineered to meet ASTM, UL 486A-486B, NEMA CC1, and NEC (National Electrical Code) compliance requirements commonly demanded by US electrical contractors, panel builders, and OEMs. Typical parts include Copper terminals, ring terminals, spade terminals, busbar links, switchgear components, grounding brackets, transformer segments, battery connectors, EV charging terminals, and micro-precision contact parts. Burr control is maintained at <0.002 in (0.05 mm), with profile accuracy of ±0.001 in (0.03 mm), ensuring compatibility with US assembly line tolerances. Our parts integrate seamlessly into Automotive wiring systems, NEC-compliant Power Distribution Boards, grounding systems, Solar and Wind energy equipment, Aerospace electronics, and Telecom hardware across the USA.

Copper Stamping for USA-Based Industries

Copper Stamping is the process of shaping pure Copper or Copper alloy sheets using precision dies to form specific electrical and mechanical profiles. Processes include blanking, piercing, bending, deep drawing, embossing, and coining, all optimized for the Copper alloys most commonly specified by US engineers—ASTM B152 (C11000), ASTM B170 (C10100 OFC), and ASTM B194 (C17200 Beryllium Copper). Sheet gauges range from 0.008 in to 0.315 in (0.2 mm to 8 mm), compatible with AWG-referenced wire harness assemblies and standard US panel building specifications. Copper stamping is critical for UL-listed electrical connectors, relay parts, power electronics assemblies, transformer segments, circuit breakers, and NEC-compliant grounding systems widely used across US industrial and commercial markets.

Copper Forging

Copper Forging uses compressive force to shape heated Copper billets or slugs, producing parts with improved mechanical strength, reduced porosity, and directional grain structure. Ideal for heavy-duty US applications such as thick-section busbars, mechanical lugs, hydraulic fittings, high-current terminals for switchgear, and industrial power distribution components conforming to NEMA standards. Forging enhances tensile strength and fatigue resistance, making forged Copper parts suitable for Automotive electrical systems, Marine connectors, Industrial switchgear, and High-current power distribution networks deployed across US infrastructure projects.

Copper Stamped Components for US OEMs

Copper Stamped Components are multi-stage engineered products manufactured through stamping, bending, threading, tapping, plating, and assembly operations. These include electrical terminals, busbar straps, clips, grounding plates, shunts, battery terminals, earthing clamps, EMI shielding components, and HVAC brackets designed to meet UL, NEMA, RoHS, and REACH requirements demanded by US buyers. Components are manufactured using high-accuracy progressive dies, ensuring batch-to-batch dimensional repeatability for US Tier 1 automotive suppliers, panel builders, and solar EPC contractors. Widely used in Smart meters (ANSI C12-compliant), Solar inverters (UL 1741-compliant), Electric vehicles (SAE J1772 / J3058), Consumer electronics, UPS systems, and Industrial automation equipment across North America.

Copper Hot Stamping & Hot Forging

Copper Hot Stamping applies controlled heat to soften the Copper sheet before stamping, enabling tighter bends, deeper draws, and complex geometries that might otherwise crack at room temperature. This is ideal for high-strength Copper alloys, deep-cavity electrical housings, and components for high-voltage US switchgear applications. Copper Hot Forging (600–800°C / 1110–1470°F) shapes dense, strong billets for power distribution units, heavy busbars, transformer connectors, and mechanical couplers used in US utility and industrial projects. Both processes improve grain structure, forming flexibility, and fatigue life—meeting ASTM and ASME mechanical performance benchmarks.

Copper Stamped Terminals – UL-Compatible & NEC-Compliant

Copper Stamped Terminals from Conex Metals are designed for maximum conductivity and minimum contact resistance, meeting UL 486A-486B and NEMA CC1 standards applicable to the US electrical market. Terminal types include ring terminals, spade terminals, fork terminals, battery lugs, male/female contact terminals, EV charging terminals (SAE J3058 compatible), and PCB terminals. In-die bending and coining ensure consistent thickness, hole diameter (in both metric and fractional inch sizes), surface finish, and contact area. Our terminals are widely used in NEC-compliant switchgear panels, Automotive wiring harnesses, Electric Vehicle charging infrastructure, Solar and Wind energy inverters, UPS systems, HVAC equipment, and utility-scale power transmission across the USA.

Copper Electrical Stamping Work – US Industrial Standards

Copper Electrical Stamping Work includes high-current conductive components such as busbar links, transformer strips, shunt connectors, power relay parts, switchgear contact plates, and power electronics hardware adhering to ASTM, UL, and NEMA specifications. Conductivity is verified to IACS% per ASTM B193, hardness per ASTM E18/E92, and surface finish per ASTM B545 (Tin plating) and ASTM B689 (Nickel plating). In-process inspection includes conductivity testing, Rockwell/Vickers hardness testing, micro-burr inspection (<0.002 in), profile measurement, and 2D vision inspection—all aligned with US quality standards including AIAG PPAP, APQP, FMEA, and SPC control plans.
