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.

Passive Buzzer Module 3.3V-5V DC

Filamet is really good

Really good filament with no moisture and printed perfectly

The module is working fine i wished you guys had a soldered one and i think you missed the anntena for this module so make sure to provide one with this module

Delivery and quality

Delivery in one day excellent
Product quality is good

Good Product

Good product and fast courier services. It was good experience ordering from Robocraze

Frequently Asked Questions

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?
