Properties of Machined Material

We offer multiple Materials for your choose, then manufacture the Best liquid cold plates to meet your application & working environment.

You can choose from:
Copper LCP - with excellent heat dissipation

Aluminum LCP - with excellent weight saving

Stainless steel cold Plate - with strong corrosion resistance
If you have any questions about the liquid cold plates & liquid cooling devices, please feel free to contact us for more information.

Material	Thermal Conductivity (W/m·K)	Specific Gravity	Corrosion Resistance
Copper	398	8.82	Strong
Aluminum	236	2.68	Lightweight
Stainless	17	7.93	Comprehensive

Materials determine coolants

The best combination of the plate's material and coolant we suggest as follow:

Copper:

Pure water (managed by ion exchange unit)
Industrial water, tap water (neutral, requires management of pH)
Antifreeze (with rust inhibitor): Ethylene glycol + pure water/Propylene glycol + pure water

Aluminum :

Pure water (managed by ion exchange unit)
Antifreeze (with rust inhibitor):Ethylene glycol + pure water/Propylene glycol + pure water

Stainless:

All kinds of coolants are available( Pure water, Industrial water, City water and Antifreeze)

How to Customize Liquid Cooling Solutions?

Before Customize Liquid Cold Plate , please give us the layout, power density, and performance requirements of your application, our team will provides technical supports about designing and testing to production etc. After you agree our propols, Please leave it to us to design, prototype, and verify your liquid cold plates.

First Considerations is Heat Sources & Coolant:

Power density & uniformity of the heat source

Coolant flow rate, inlet pressure, and allowable pressure drop

Next Considerations is Required Parameters:

Compatibility Parameters: corrosion resistance, electrical isolation, temperature ranges, and connection standards

Then Considerations is Manufacturing & Welding methods:

Manufacturing methods: CNC machining, Injection Moulding , Stamping , Cold Forging, Die Casting

Welding methods: FSW, TLP or VB brazing

Last Considerations is Surface Finish & Treatment:

Surface Finish & Treatment: Anodizing, Ni(Nickel) plating, or special coatings
