Aluminum Alloy 1050 Aluminum Strip (0.8–1.5mm × 800mm, Bright Surface) for Heat Sinks

Product Description:

The Aluminum Alloy 1050 aluminum strip (thickness 0.8–1.5 mm, width 800 mm) is a commercially pure aluminum (≥99.5 % Al) in H14 / H24 temper with a mirror-bright surface specially developed for heat-sink extrusion and stamping.

• Thermal conductivity: ≈ 230 W/m·K

• Elongation: 12–18 %

• Density: 2.71 g/cm³
  The bright finish is achieved by precision cold-rolling + chemical polishing, giving ≥ 85 % reflectivity and perfect anodizing acceptance.
  Lightweight, 100 % recyclable, and ready for CNC fin-cutting, folding, or extrusion-bonding, the 800 mm width feeds the widest automatic fin presses in one pass

Case Studies   

1. NVIDIA RTX 4090 (USA)
   1050 bright strip → stamped wavy fins → black-anodized → 8 % lower GPU temp.

2. Huawei 5G AAU (China)
   1.2 mm × 800 mm 1050 coil → 3 200 fins bonded in one shot → 30 kg weight saved per unit.

3. BMW i4 Headlamp (Germany)
   1.0 mm 1050 → micro-channel folding → clear anodized → 50 000 h life.

4. EV Charger (India)
   0.8 mm 1050 → roll-formed pin-fins → natural finish → 40 % cost cut vs. die-cast.

International Applications

Used worldwide wherever efficient, beautiful heat dissipation is critical:

• North America: Intel® & NVIDIA® partners in California stamp 1050 strips into GPU heat sinks.

• Asia: Foxconn (Shenzhen) & Delta Electronics (Shanghai) extrude-bond 1050 fins onto copper bases for 5G base-station coolers.

• Europe: Infineon (Munich) & NXP (Eindhoven) use 1050 bright strips for automotive LED headlamp sinks.

• Emerging Markets:(Pune) & BYD (São Paulo) cool EV inverters with locally anodized 1050 fins.

Also seen in LED street lights, telecom cabinets, and medical imaging equipment.

Trends

• Micro-Channel & 3D Fins – 1050’s ductility enables 0.2 mm wall thickness.

• Clear & Colored Anodizing – bright base = vivid Apple-white or midnight-black sinks.

• Liquid Cold Plates – 1050 strip brazed to copper tubes for 1 kW+ servers.

• Carbon-Neutral Factories – 100 % recycled 1050 coils already in production.

Trend Table

Upcoming Applications

• 2030 AI racks: 1050 micro-channel plates for 3 kW chips

• 6G small cells: roll-formed 1050 “origami” sinks

• Solid-state batteries: ultra-wide 1050 cooling belts

• Space-grade CubeSats: vacuum-brazed 1050 radiators
