1100 H14 Aluminum Sheet 0.3-3mm Heat Exchanger Fin Stock Mill Test Certified

Our 1100 H14 aluminum sheet is produced in thickness from 0.3mm to 3.0mm and slit to width from 20mm to 1250mm for heat exchanger fins, radiator plates, heat spreaders and conductive parts. 1100 combines high thermal and electrical conductivity with enough strength for fin forming and light structural duty.

Thermal conductivity is about 222 W/m.K and electrical conductivity about 59 percent IACS. Gauge is measured in line and held at plus or minus 0.02mm, so fin forming tools do not need re setting between lots, and flat, stress balanced sheet avoids fin wave and block distortion during brazing.

Every lot ships with an EN 10204 3.1 mill test certificate carrying the heat number, chemical composition and mechanical results, together with RoHS and REACH declarations for EU market entry. Slitting is done in house with burr controlled edges to your exact fin width.

• Conductivity you can design with: measured thermal and electrical values are stated on the mill test certificate, so your thermal calculation is backed by data.
• Gauge stability: in line gauge control at plus or minus 0.02mm keeps fin height and fin pitch within tolerance after forming.
• Flat and stress balanced: annealing and leveling before slitting prevent fin wave and block distortion in the brazing furnace.
• Clean, oil free surface: residue free surface improves brazing wetting and reduces flux related rejects.
• Burr controlled slitting: in house slitting to your width removes a process step and avoids burr related fin damage.
• Full documentation: mill test certificate, RoHS and REACH declaration and dimensional report ship with each batch.

1100 H14 sheet is used where heat or current has to move through the metal efficiently.

1. Heat exchanger fins, radiator fins and charge air cooler fins.
2. Heat spreaders, heating plates and thermal interface parts.
3. Battery cooling plates and thermal conduction shims.
4. Electrical contacts, busbar shims and conductive gaskets.
5. Cookware and kitchen equipment parts requiring heat conduction.
6. Decorative and functional sheet metal parts with coating or anodizing.

We customize alloy, temper, thickness, width, slitting width, coil inner diameter and packing to match your fin press and brazing line. Slit coil can be supplied eye to sky or eye to wall, and flat sheet can be cut to length for small batches or trial runs.

• Full-process manufacturer: casting, hot rolling, cold rolling, annealing, leveling, cut to size, inspection and export packing are completed inside our own plant, so plate quality and delivery are controlled by one team instead of being outsourced to several workshops.
• 26 years of aluminum processing: established in 1999 with more than 2000 employees, annual sales of USD 30-35 million and export business covering more than 60 countries.
• Stable capacity: 5000 tons of monthly output supports long term supply contracts, repeat orders and batch-to-batch consistency, with reserved production slots for regular buyers.
• In-house laboratory: direct reading spectrometer, tensile and elongation testing machine, salt spray chamber, ultrasonic inspection, thickness gauge and flatness measurement are used on every batch.
• Certified quality system: ISO 9001:2015 management system, ASTM B209 and EN 485 material standards, EN 10204 3.1 mill test certificate, SGS and TUV third party inspection accepted, factory audit welcomed.
• Engineering support: our technical team helps buyers select alloy, temper and surface treatment for their welding, bending, drawing or coating process before the order is placed.
• Fast commercial response: quotation within 24 hours, free samples in 3-5 days, 7-20 days production lead time and complete shipping documents for customs clearance.
• Export logistics: loading from Qingdao, Shanghai, Ningbo or Tianjin with optimized 20GP and 40HQ loading plans, ISPM 15 heat treated pallets and full document service.

Our technical team reviews your fin geometry, forming method and brazing cycle, then recommends alloy, temper and gauge tolerance accordingly.

Conductivity and mechanical data are retained per batch, so any thermal or forming issue can be traced to the exact coil.

Repeat orders keep the same rolling and annealing route, so fin forming behaviour stays consistent between deliveries.

Coils are wrapped with anti rust paper and plastic film, secured with steel strapping and packed eye to sky on ISPM 15 heat treated pallets.

Flat sheets are interleaved and palletised with edge protection to avoid bending and surface damage.

Loading plans are prepared by coil width and weight to maximize container payload, with full documents for customs clearance.

Q1: Are you a factory or a trading company?
We are a manufacturer with our own casting, rolling, annealing, leveling and cut to size lines in Henan, China. Buyers are welcome to visit the workshop or arrange a third party factory audit.

Q2: Can I get a free sample?
Yes. Free samples are prepared in 3-5 days and the buyer only covers the freight, so material performance and surface quality can be verified before the mass order.

Q3: What is the MOQ?
1 ton per size for regular production. Mixed sizes can be loaded in one container and trial orders are negotiable.

Q4: How is quality guaranteed?
Every batch is tested in our own laboratory and shipped with mill test certificate, mechanical property report and dimensional inspection report.

Q5: What payment terms do you accept?
T/T, L/C at sight, D/P and D/A. Other terms can be discussed for long term cooperation.

Q6: Do you provide a mill test certificate with heat number?
Yes. EN 10204 3.1 certificate with heat number, chemical composition and mechanical results is issued for every lot.

Q7: Can you slit to my exact fin width?
Yes. In house slitting from 20mm to 1250mm, with burr controlled edges and width tolerance agreed before production.

Q8: Is 1100 suitable for brazing?
Yes. The oil free, residue controlled surface is suitable for vacuum brazing and controlled atmosphere brazing when the filler and flux are matched to the process.
