Cold Plates & Heat Sinks places specific demands on the alloys that serve it. Jiangsu DZX Alloy supplies Copper & copper alloys for this duty, combining 24+ years of precision-alloy manufacturing experience with an ISO9001 triple-inspection system, a 12,000 m2 self-owned factory and full batch traceability. Within Data Center Cooling, cold plates & heat sinks combines these requirements in its own way.
Liquid cooling — cold plates, coils, CDUs and immersion tanks — is becoming the thermal backbone of AI-scale data centers. Jiangsu DZX Alloy supplies copper-nickel alloys, 316L stainless and copper with the wall-thickness tolerance and cleanliness that leak-free thermal loops demand.
General Requirements for Cold Plates & Heat Sinks
- Wall-thickness tolerance: consistent walls that survive bending without thin-spot cracking.
- Cleanliness: residue-free internal surfaces protecting pumps and micro-channels.
- Joint reliability: consistent header diameters for brazed and welded connections.
- Coolant compatibility across copper, CuNi and stainless circuits.
- Supply-form fit: materials must be available in the forms fabrication requires — typically plate, strip, tube, wire / strip, tube.
Recommended Materials & Specifications for Cold Plates & Heat Sinks
The following grades and specifications apply to this application; all values are as supplied by Jiangsu DZX Alloy with per-batch certificates:
| Material | Representative grades | Key properties | Available forms |
|---|---|---|---|
| Copper & copper alloys | C1100 | high thermal conductivity | plate, strip, tube, wire |
| Copper & copper alloys | C10100 (OFHC) | ultra-high purity, electrical conductivity | strip, tube |
Copper & copper alloys (C1100) is specified for its high thermal conductivity. Jiangsu DZX Alloy supplies it as plate, strip, tube, wire, with dimensions produced to drawing; supported fabrication routes include bending, welding, stamping and machining as the form allows. Copper & copper alloys (C10100 (OFHC)) is specified for its ultra-high purity, electrical conductivity. Jiangsu DZX Alloy supplies it as strip, tube, with dimensions produced to drawing; supported fabrication routes include bending, welding, stamping and machining as the form allows.
Available supply forms by grade:
- Copper & copper alloys: plate, strip, tube, wire
- Copper & copper alloys: strip, tube
Customisation: Grades, diameters, wall thicknesses and lengths can be manufactured to customer drawings, and samples are available on request.
Application Scenario Deep Dive: Cold Plates & Heat Sinks
In liquid cooling, a leak is not a warranty claim — it is a data-center outage. That is why coil suppliers are chosen on wall-thickness tolerance and internal cleanliness, verified with documentation that plugs directly into the integrator’s leak-test records.
When high thermal conductivity governs the duty, Copper & copper alloys is the typical first call; Copper & copper alloys is preferred where ultra-high purity, electrical conductivity matters more. Jiangsu DZX Alloy’s engineering team can review your duty conditions and confirm the grade, condition and tolerance before ordering.
Cold Plates & Heat Sinks does not operate in isolation: within Data Center Cooling it sits alongside Liquid-Cooling Coils & Heat Exchangers, Cooling Loops & Manifolds, Immersion-Cooling Systems, and material choices made here often share grades, documentation and inspection practice with those duties. Reviewing the neighbouring application pages is the fastest way to see where specification boundaries lie.
