Buy Aluminium Heat Sink Online in India

The most common thermal solution product is an aluminium heatsink. After iron, aluminium (aluminium) is the metal that is used the most globally. Aluminium is the third most prevalent element in the Earth's crust, following silicon and oxygen. Extruded aluminium heatsinks in particular meet the requirements of the majority of projects. The metal is thin and has a respectable level of thermal conductivity.

Heat Sink Installation Guide

Use these step-by-step visuals to help beginners install heat sinks correctly on ICs, regulators, Raspberry Pi, and other boards.

1. Clean the Surface

Make sure the chip or metal surface is free from dust, old thermal paste, and oil.

2. Apply Thermal Paste or Thermal Pad

Use a thin, even layer of thermal paste or place a pre-cut thermal pad on top of the chip.

3. Mount and Secure the Heat Sink

Gently press the heat sink onto the chip and hold for a few seconds. Use clips, screws, or adhesive pads as required.

Thermal Conductivity Comparison

Material	Approx. Thermal Conductivity (W/m·K)	Common Use	Notes
Aluminum (typical alloys)	≈ 150–200	Most standard heat sinks	Lightweight, cost-effective, easy to machine.
Copper	≈ 380–400	High-performance heat sinks, base plates	Better heat transfer but heavier and more expensive.
Aluminum + Copper Hybrid	Mixed (copper base, aluminum fins)	CPUs, GPUs, high-end drivers	Copper spreads heat, aluminum fins dissipate it efficiently.
Ceramic / Insulated Composites	≈ 10–30	Electrically isolated packages	Lower conductivity but great electrical insulation.
Thermal Pads / Tapes	≈ 1–8	Gap filling between chip and heat sink	Convenient, but less conductive than paste or metal.

Aluminium Heat sink working

First, the degree of thermal conductivity varies amongst metals. The efficiency with which a metal transfers heat increases with its thermal conductivity. Aluminium is one of the most popular metals used in heat sinks. Thermal conductivity of aluminium is 235 watts per Kelvin per metre (W/mK).

Heatsinks are very important electronic components as to keep the temperature around a lighting device under control and to ensure the product has a long operating life, a heat sink is necessary. A heatsink is used to regulate temperature when a device's design cannot efficiently dissipate surplus heat into the surrounding air.

1. Is aluminum good for heat sink?

The most typical material used in heat sinks is aluminum. Extruded aluminum heat sinks in particular meet the requirements of the majority of projects. The metal is thin and has a respectable level of thermal conductivity.

2. What type of aluminum is used for heat sinks?

A Guide to Heat Sink Aluminum Alloy Selection

The 6000 family of aluminum alloys are the best choice since they are sturdy, pliable, and perfect for extrusion. The Alloys 6060, 6061, and 6063 series are the most popular for designing sinks out of these.

3. Which heat sink is best?

Aluminum is a great material for most sinks since it is lightweight, affordable, and simple to manufacture. The most popular alloys are alloys 6061 and 6063, whereas alloys 1050 and 1100 are purer and have a somewhat higher conductivity. The thermal conductivity of it is around half that of copper.

5. Is heat sink removable?

Yes, sinks are removable. Use a hair dryer and turn the heat and fan all the way up. Use pliers to slowly twist the heatsink back and forth until the chip is released as the sink becomes hot.

6. Do we need heat sink for raspberry pi?

The Raspberry Pi 4 operates well under normal circumstances without the need for any kind heat sink for raspberry pi, and software throttling maintains everything within safe operating ranges. However, you should certainly need a set of high-quality sinks if you're overclocking or utilizing bespoke software.
