6063-T5 Aluminium Heat Sink

  • The aluminium heat sink is a type of heat transfer components that absorb and dissipate the heat from electronic or mechanical devices, helping to keep that device at the proper temperature. It is widely used in industrial and commercial electronic devices. CHAL is one of the most famous heat sinks manufactures in China, we keep improving aluminum extrusion profile technology and make it possible to produce high-performance aluminum heat sinks for cooling mechanisms. Aluminium heat sinks are designed to maximize the surface area in contact with the coolant fluid and cool air. and that need a combination of greater strength and lighter weight, aluminum extruded heat sink make it with a thinner thickness, a narrow tolerance, and higher thermal conductivity.
  • CHAL is an expert in standard and custom-designed aluminium heat sink, offering customers a full service from design to production, technical support, fast delivery, and providing a wide selection of high-quality products readily available in stock, at the most competitive prices.

Why Choose Aluminium As The Most Common Material For Heat Sinks?

Aluminium is the most common material for heat sinks. In particular, extruded aluminium heat sinks fit the needs of most heat transfer projects.

1. Aluminium alloys are the most common material for producing aluminium heat sink. This is because aluminium costs less than copper, and it is lightweight. So that can save some material costs. Aluminium is also a cost-effective alternative for vast industrial applications.

2. Aluminium alloy has relatively good thermal conductivity. Thermal conductivity measures the ability of a metal to conduct heat. This property is a key feature to be considered of the heat sink, you can see below table, aluminium and copper have high thermal conductivity, while steel and bronze have lower heat conductivity. Aluminium alloy 1050A has one of the higher thermal conductivity values at 229 W/m•K but is mechanically soft. Aluminium alloys 6060 and 6063 are commonly used, with thermal conductivity values of 166 and 201 W/m•K, respectively. The values depend on the temper of the alloy. Also, for pure metals, thermal conductivity stays roughly the same with increases in temperature. However, in alloys, the thermal conductivity increases with temperature.

3. Aluminium alloy has good formability, so that ease of fabrication. Extruded aluminium heat sink can be made with several channels or fins that increase the heat transfer through a higher surface per volume ratio.

4. Aluminium alloy has good corrosion-resistant, and an excellent choice wherever strength is required.

5. Aluminium has a higher strength-to-weight ratio than steel, brass or copper.
