White metal model parts and zinc pest?

[SawgrassRaven]

Gentlemen, good day.

I am taking a hard look at Model Factory Hiro's 1/12 K670 Ferrari SF71H. I see it comes with white metal parts. I am familiar with die cast zinc rot, but I have never worked with white metal parts on a model. I am wondering what this white metal is made of. I would hate to pay $600 for a kit to have to later worry if the white metal parts may be/are subject to zinc rot.

I've found the general concensus to be that it is pewter, similar to fantasy figures, but cannot confirm this.

Anyone have any input on this? What has been your experience? Any info/advice welcomed.

Thanks in advance!

White Metal Alloy is made up of the following metals. Tin , Lead. Bismuth, Zinc and or Cadmium. HFM use the top grade of White Metal so you wouldn't get the " Zinc " rot that you will see in Die-Cast mass produced cars.

If we are to believe Wikipedia (because, why not?), zinc pest is actually caused by lead contamination in zinc alloys (like white metal).

See https://en.wikipedia.org/wiki/Zinc_pest

White metal is just a name of a range of alloys (not a specific formula). So is "pot-metal". Then there is Zamak too.
