40*40*1mm/3mm/5mm Computer PC laptop red Copper heatsink Heat conduction cooler cooling plate block,Can customized size

Reminder:

Please note the surface of the copper sheet we have no processing grinding( the surface is not smooth)

non-specular surface, There may be a little scratches.The copper plate is very soft, As long as you use

sandpaper gently grinding the surface , it will become a smooth surface.

There are tolerance in the cutting of copper plates(1mm-2mm),Thickness may negative tolerances,

If you are very strict,please reconsider seriously.

Pure Copper: red copper, has good electrical conductivity and thermal conductivity, excellent plastic and

easy hot and cold pressure processing. Used extensively for the manufacture of wires, cables, brushes,

EDM dedicated electric conductivity of copper corrosion and other requirements of a good product.

Features: High purity, fine organization, the oxygen content is very low. Nonporous, trachoma, loose excellent

conductive properties, high surface accuracy, the heat treatment process, the electrode had no direction,

suitable for playing fine, fine playing, good thermal channel, workability, ductility, corrosion resistance and

weather and so on.

Uses: Can be used in electrical appliances, distilled construction and chemical industry, especially electrical

terminal printed circuit board, with copper wire shielding, bus terminal. Electromagnetic switch, pen, house root

panels.

The proportion of copper is: 8.89g / (mm) ,copper Cuge99.95% ,oxygen O <003 , Conductivity ge57ms / m2,

hardness ge85.2HV ,Brinell hardness (HB) 35- 45.
