Custom Tin Plated Copper Strip | Solderable, Corrosion‑Resistant Strip for Busbars & Electrical Connectors

Custom Tin Plated Copper Strip

はじめに

1. Tin Plated Copper Strip is a high‑conductivity copper strip coated with a uniform tin layer by electroplating or hot‑dipping. The copper core provides excellent electrical and thermal conductivity, while the tin coating significantly improves corrosion resistance, solderability, and contact stability, and helps prevent copper migration. This makes tinned copper strip widely used for busbars, electrical connectors and terminals, earthing strips, battery tabs, switchgear components, and power distribution systems in automotive, renewable energy, and industrial installations.

2. We offer fully customizable Tin Plated Copper Strips, including copper grade (such as C11000/ETP, C10100/OF), strip thickness, width, temper, and tin plating thickness (bright or matte). Material can be supplied in coils or cut‑to‑length, with controlled mechanical properties and surface finish suitable for punching, bending, stamping, and CNC processing. Our strips are produced with reference to relevant ASTM/EN standards for copper strip and tin electroplating, ensuring consistent conductivity, strong adhesion of the tin layer, and reliable performance in crimping, soldering, and bolted connections. OEM/ODM and engineering support are available to match your drawings and application requirements.

   仕様

   タイプ	Tin Plated Copper Strip / Tinned Copper Strip / Tin-Coated Copper Busbar Strip
   Structure	High‑conductivity copper strip with a continuous tin coating applied by electroplating or hot‑dip tinning; tin layer firmly bonded to the copper substrate
   Material Grade (Copper)	ETP copper (C11000), oxygen‑free copper (C10100/C10200), or equivalent high‑purity copper grades according to ASTM/EN/GB standards
   Cu/Sn Ratio (Thickness)	Copper base thickness plus tin layer thickness customizable; typical tin thickness from approx. 2–15 µm per side (heavier coatings on request), optimized for solderability, corrosion resistance, and cost
   Electrical & Thermal Cond.	Copper core provides excellent electrical and thermal conductivity (≈ 100% IACS); tin coating has minimal impact on bulk conductivity while greatly improving surface solderability and contact stability
   フォーム	Flat strip or busbar, supplied in coils or cut‑to‑length bars; suitable for punching, bending, and CNC machining for connectors and power distribution components
   Thickness Range	Customizable total thickness, typically from about 0.1 mm to 10 mm or more (for busbars); tin layer thickness adjusted independently according to application and standard requirements
   Width & Length	Strip width from a few millimeters up to 300–600 mm (depending on thickness and production route); supplied as continuous coils (tens to hundreds of meters) or fixed cut lengths per customer specification
   Coating Method	Electro‑tin plating (bright or matte) for thin, precise coatings; hot‑dip tinning for thicker, more robust coatings where required
   Surface Finish	Bright, matte, or semi‑bright tin surface; controlled roughness to optimize solder wetting, crimping, and contact performance; optional anti‑tarnish treatment
   Mechanical Properties	Determined mainly by copper grade and temper (soft, half‑hard, hard); good formability for stamping, bending, and busbar fabrication while maintaining high conductivity
   Corrosion Performance	Tin layer improves resistance to atmospheric corrosion and prevents direct copper oxidation and migration; suitable for humid and industrial environments, especially in electrical enclosures
   Solderability & Joining	Excellent solderability (Sn layer), compatible with soft soldering, brazing, and crimping; good contact performance in bolted, riveted, or spring‑clamp connections
   Dimensional Tolerances	Tight control of thickness, width, and flatness according to relevant copper strip standards (e.g., ASTM B152/B272, EN/GB equivalents) to ensure stable feeding and forming in automated production
   Standards & Reference	Manufactured with reference to standards for copper strip and tin coatings, such as ASTM B152 (Copper Sheet, Strip), ASTM B272 (Copper Bus Bar), and ASTM/IEC/EN specifications for electro‑tin plating
   Application Range	Power busbars, switchgear and control panels, earthing/grounding strips, battery tabs and connectors, automotive and EV power distribution, renewable energy systems, terminal blocks, and general electrical connection hardware
   Processing Capability	Supports slitting, shearing, punching, stamping, bending, deep drawing (within limits), drilling, and CNC profiling; suitable for high‑volume automated production lines
   Customization	Tailored copper grade, temper, total thickness, strip width, tin coating thickness/type (bright or matte), coil inner/outer diameter, and pre‑punched or pre‑formed parts according to drawings or CAD files
   Packaging	Supplied in wrapped coils or bundled strips with edge protection; anti‑corrosion paper/film and pallet/wooden‑case packaging available for safe transport and long‑term storage
