Re: [gingery_machines] Chuck backplates

 

I would be concerned about the safety of any zinc rich alloy. This is a personal opinion of course but I've never thought of zinc alloys being extremely malleable. Years ago I worked in a zinc die cast shop and learned that the alloy is critical to product strength. Of course ZA12 doesn't appear to be a die cast alloy so that experience doesn't count. In any event I'd be real concerned about ZA alloys where safety is a big concern.

Wheelium of course should be much better as it is used for rotating objects that have to take a lot of shock.

I'm by no means an expert here so take this as is.
