H502 with expansion board

Overview

H502 is an ultra-thin one-piece copper heatsink specially designed for Raspberry Pi 5 Model B. CNC-processed copper heatsink with precise cutouts, designed to seamlessly fit the Raspberry Pi 5B motherboard.

Through-hole screw holes allow expansion boards installed on top of the H502 heatsink or on the bottom of the H502 heatsink. H502 also supports 30x30mm cooling fan installation for better heat dissipation.

I will comment it is a very beautiful finish that looks polished and/or electroplated with pure copper, it is a near mirror finish. It is both functional and beautiful. I've encased it fully in acrylic with a different housing.

the EU RoHS “6(c)” exemption allows up to 4% lead in copper alloys (brass) by weight. - Copper Development Association

How children actually get exposed to lead:

The big risk route is ingestion (hand‑to‑mouth or mouthing an object). This is why California targeted brass keys—kids put them in their mouths and measurable lead transfers from handling/mouthing.

Alright, I figured it out:

Mechanical strength – Pure copper is very soft and malleable. Under repeated tightening, it would deform or strip. Brass (copper + zinc, sometimes with a trace of lead) is much harder and keeps threads intact. That’s important for standoffs which get screwed/unscrewed.

Corrosion resistance – Pure copper oxidizes rapidly (green patina). Brass resists tarnish better and maintains good contact over years without needing surface coatings.

Machinability – Adding zinc (and a small amount of lead in some brass alloys) makes the material much easier to machine precisely, especially for threaded parts. That reduces cost and improves quality control.

Cost – Brass is cheaper than using high-purity copper for mechanical parts. Copper is usually reserved for high-current traces or heat conduction, not threaded standoffs.

So the alloying with zinc (to form brass) and sometimes lead (to improve machinability and lubricity) is exactly to balance strength, durability, corrosion resistance, and manufacturing cost. Pure copper would simply be too soft and impractical for screws and standoffs.

Basically don't grind or sand it, don't let your kid swallow this entire heatsink. Its not a risk. Peace n love homies.

Hello,Thank you for the feedback. I think your explanation also addresses the doubts of many users; usually, they are unaware of the production process of metal radiators.It would be very helpful for other users if you included this section in the product review as well.

Why would you put lead in this?

What size of shim could be used to replace the thermal pad for the CPU?
