Aluminum Strip Coil 1060 3003 Electrical Conductivity 237 W mK Thermal Conductivity Special Shape Cut to Length OEM

A 1050 / 1060 / 3003 aluminum strip coil built for current-carrying and heat-dissipating assemblies: 61% IACS electrical conductivity, 237 W/(m·K) thermal conductivity, profiled cross-sections to drawing and fixed-length blanks, all under an OEM strip programme for repeat production runs.

• Stable alloy chemistry keeps resistivity repeatable from coil to coil, so automated stamping and welding lines see less scrap
• The high thermal path lets busbars, battery tabs and heat sinks run cooler under continuous load
• Low oxide inclusion content supports reliable spot welding and ultrasonic bonding without pre-cleaning
• Formable tempers hold bend radii without cracking, including on narrow slit and profiled sections

The strip is ordered to a drawing and cut to a fixed length, so it drops straight into the customer’s press, welding cell or assembly fixture instead of being re-worked on site.

1. Power transmission and distribution

• Busbar and conductor strip for low-voltage switchgear, distribution boards and metering cabinets
• Transformer winding strip and foil conductor where stable resistivity keeps eddy-current losses predictable
• Earthing strip, neutral link and terminal connector strip for panel builders

2. New energy and battery systems

• Battery tab and busbar strip for prismatic and cylindrical cell modules
• Liquid-cooling plate and cold plate strip for pack thermal management
• Heat-spreader strip between cells and module housing to flatten temperature gradients

3. Electronics and heat dissipation

• Heat sink base strip, LED thermal interface strip and driver housing strip
• EMI and RF shielding strip, grounding contact strip and connector shell material
• Profiled strip for stamped contacts, where the shaped section saves a secondary forming step

4. HVAC and ventilation ducting

• Flexible duct aluminium strip in 55 mic and 70 mic gauges, supplied in narrow slit coils
• Duct reinforcement and spiral tube forming strip
• Heat exchanger fin stock and air-conditioning cabinet trim strip

5. Automotive, rail and marine electrical hardware

• Wiring harness flat conductor, fuse box link and grounding strap
• Trim and structural strip for rolling stock interiors and cable trays
• Shipboard cable shielding and earthing strip, documented to classification-society requirements

6. Construction, signage and general fabrication

• Aluminium edge trim, expansion joint strip and curtain wall connector strip
• Signage frame and light box profile strip
• Fixed-length blanks for stamping, bending and CNC finishing shops

• Alloy and temper selection matched to your conductivity, bend radius and welding process
• Special shape tooling developed from your drawing in 15–20 days, with DFM and springback notes before the tool is cut
• Coil or blank supply — full coil, narrow slit coil, or fixed-length bundle, your choice of ID and coil weight
• Surface and finish options including color matching to RAL swatches and embossed patterns
• OEM strip programme: logo printing, private-label cartons, neutral packing, barcode labelling for line-side delivery

• Technical consultation: alloy and temper recommendation against current-carrying capacity and forming process, answered by an engineer within one working day
• Quotation and drawing review: DFM feedback and tolerance confirmation before tooling commitment
• Samples: free A4-size specimens of standard grades for conductivity and forming trials; shaped and fixed-length samples quoted at tooling cost
• Documentation: mill test certificate with chemical composition, tensile strength, elongation and conductivity per heat number, plus ISO 9001 and RoHS declarations
• Inspection: SGS, BV, TUV or Intertek third-party inspection before loading, with photo and video reports
• Order tracking: weekly production and shipping milestones, coil and pallet photos before dispatch
• After-sales: claims answered within 24 hours; replacement or credit for verified dimension, temper or surface deviations
• Trade terms: EXW, FOB, CIF and CFR; T/T, L/C, D/P and D/A; frame agreements with locked pricing

• Coil packing: tension wound with interleaved paper, VCI anti-corrosion film, plastic or hardboard edge rings
• Pallet packing: fumigation-free plywood pallet, steel strapping at 3 points per coil, corner protection
• Blank packing: strapped and shrink wrapped bundle; wooden case for shaped profiles to prevent deformation
• Marking: alloy, temper, size, heat number, gross and net weight on every unit, plus shipping marks to your instruction
• Loading: 20’ GP about 20–25 tons, 40’ HQ about 25–28 tons, with timber dunnage
• Ports: Qingdao, Tianjin and Shanghai; inland rail and truck delivery on request
• Lead time: 7–15 working days for standard grades, 20–30 days for tooling and fixed-length runs
• Documents: commercial invoice, packing list, bill of lading, certificate of origin (CO / Form A or E), mill test certificate, insurance certificate

Ordering: Send the alloy, temper, thickness, width, cross-section drawing and cut length — we will quote the conductive strip grade and confirm tooling lead time within one working day.
