I was surprised to be told last night that Weber carburetor bodies are made of Mazak (as it is called in the UK), otherwise known as Zamak. This is a mainly zinc alloy with about 3-4% of each of aluminium and copper, with some magnesium also.

Is Mazak used for Weber bodies?

I have heard this of some of Weber's low-priced carbs (they have a very shiny, silvery surface), but have seen nothing authoritative to confirm this. I believe the DCOEs, IDFs, IDAs, and other performance models to be aluminum, based on the two I've welded up, machined, and threaded.

If they are Mazak, I would expect to see some de-zincafication (?) pimples appearing on my 40 year old examples.

Hey Greg, see you're in Santa Rosa. Got a brother in Cazadero, small world.

I have been told by a reliable contact in the historic racing car scene in the UK that Weber carburettor bodies are made from aluminium, and not from Mazak.

John Larkin.

The statement above is correct, they are aluminium
