Nickel Plated Brass Positive Negative Conductive Sheets 1.0mm Thick Battery Contact Sheets with M3 Thread Holes

Our custom positive and negative brass conductive sheets are high-precision stamped conductive metal components built for electronic internal power connection systems. Constructed from premium 1.0mm thick brass raw stock, every conductive sheet is formed by high-speed precision stamping machines to secure strict dimensional uniformity. After forming procedures, all workpieces go through vibration grinding to thoroughly clear sharp edge burrs, followed by full nickel electroplating surface finishing to upgrade oxidation resistance, anti-rust performance and stable electrical conductivity.

The positive and negative conductive contact sheets adopt fully symmetric structural design. Each single conductive sheet comes with four mounting holes, two of which are pre-tapped with standard M3.0 internal threads for quick screw assembly without secondary tapping work.

• Internal conductive connections of consumer lithium battery packs
• Mini power supply modules and switching power adapters
• Circuit boards of household intelligent control equipment
• Internal power transmission components of portable electronic gadgets
• Conductive terminal parts for small energy storage modules
• Internal conductive contact pieces of all types of battery chargers

As a professional OEM custom precision metal stamping manufacturer, we supply comprehensive custom service for brass conductive sheets and electronic terminal metal pieces:

• Drawing & Sample Customization: Accept customer CAD engineering drawings or physical samples to develop exclusive conductive sheet products
• Raw Material & Thickness Customization: Adjust brass sheet thickness (standard 1.0mm, custom thickness available), provide alternative copper alloy materials on request
• Structural Customization: Customize product length, width, height, hole count, hole positions and internal thread standards
• Surface Treatment Customization: Modify nickel plating thickness, offer alternative surface finishing solutions
• Batch Order Customization: Support small trial sample batches and large-volume mass production orders
• Secondary Machining Customization: Add tapping, bending, counterboring and other secondary processing procedures as required

• Solve unstable conductivity troubles: High-purity 1.0mm thick brass base retains steady electric transmission performance; nickel plating blocks oxidation which causes current attenuation
• Remove sharp burr assembly risks: Complete vibration grinding deburring eliminates all edge burrs, preventing scratches on circuit boards and battery cells during assembly
• Fix mismatched screw fitting problems: Precisely pre-tapped M3.0 thread holes avoid manual tapping errors, perfectly cooperate with standard M3 screws for tight, stable assembly
• Resist short service life issues: Uniform nickel plating forms a durable anti-corrosion barrier, extending product lifespan in damp electronic operating environments
• Eliminate dimensional deviation problems: Precision stamping technology with ±0.02mm tolerance guarantees consistent sizing across all finished 1.0mm conductive sheets, compatible with automatic assembly production lines
• Lower custom production barriers: Flexible OEM custom service adapts to exclusive electronic equipment structural designs, adjustable sheet thickness beyond standard 1.0mm, no need for clients to modify their product plans

• Incoming Raw Material Inspection: Full chemical composition testing for all incoming 1.0mm brass sheets to guarantee material purity standard
• In-Production Dimensional Monitoring: Automatic digital caliper testing during stamping to check thickness, length and width, keep all sizes within ±0.02mm tolerance
• Burr Completeness Inspection: Full visual and tactile check after vibration grinding to ensure zero leftover edge burrs
• Nickel Plating Quality Testing: Plating thickness measurement and coating adhesion test to prevent plating peeling
• Thread Precision Verification: Manual screw fitting test for all M3 tapped holes to guarantee smooth screw locking
• Final Full Finished Goods Inspection: Random sampling thickness check, conductivity testing and comprehensive appearance screening before packaging and delivery
• Batch Quality Traceability: Complete production and inspection records preserved for every production batch to support full quality traceability

• Can you manufacture custom conductive sheets based on my engineering drawings?

  Absolutely, we provide full OEM custom service, and we can produce conductive sheets strictly following your CAD drawings or physical samples, including customized thickness different from our standard 1.0mm.

• What is the minimum order quantity of custom brass conductive sheets?

  We accept small trial orders and large mass production orders; MOQ is negotiable based on your project requirements.

• Am I allowed to change the nickel plating surface finish of these positive negative conductive sheets?

  Yes, we can adjust nickel plating thickness and supply other alternative surface treatment solutions upon your request.

• What dimensional tolerance can your precision stamping process reach for 1.0mm thick conductive sheets?

  Our automated stamping production lines deliver stable ±0.02mm dimensional tolerance for standard 1.0mm thick brass conductive sheet products.

• How long is the lead time for custom samples and bulk orders?

  Custom sample lead time is 3–7 working days; mass production delivery time depends on order quantity, we will confirm the exact schedule once your order is confirmed.
