Howdy! Utah Laws

Hello all, first post here. Just getting into some Home foundry work and heard that if I do any Ingots that I need to have them stamped and dated by someone who is licensed? I am wondering if that is true and if so how does one get that license? Mostly doing AL and Brass but I do have some copper that I have collected over the years and if I don't cast it into art(or product of some kind) mostly don't want to start off on the wrong foot.

As it is for fun right now I'm not too worried.

So far I have an ingot of 4.4lbs brass from a Building that I had re-keyed Lol glad to not carry it around every day!

Thanks all

Welcome.

That really depends on the yard : one of my locals won't take non ferrous cast in ingot molds, but will take them cast in shapes or strips. Reasoning behind this is that it's easy to hide heavier metals in a thick ingot.

Another yard takes metal "In any form" (my favorite).

Give some local yards a call and ask what they take.

Can't speak to the policies of any particular scrapyard but there is nothing in the Utah code under "regulation of metal dealers" about buying or selling ingots. What part of Utah are you in? I've got some clients in the SW quadrant of the state and occasionally sell to a yard in SLC and am in state every couple of weeks usually.

Im no lawyer, but I don't think you NEED to have them stamped or certified or whatever.... I think a lot of yards just may not take them as there is a risk/liability on their end and it's easier for them to just not take the risk. Like if you bring in a 5 inch copper block whose to say you didn't drop a brick in there, or speckle lead into it. Or what if it's only 65% copper and 35% iron but you can't tell just by looking at it. Basically things can get dicey with ingots and yards. But I've seen tons of people sell them on eBay for a pretty decent mark up over scrap value anyways.... So I don't think the scrap yard would be your best bet for ingot sales anyways.

In SLC county for the moment. Soon to be Eagle Mt.

The "hide heavier metals" in an ingot, most metals float on the surface of molten non-ferrous metals
I have melted "dirty" aluminum. bolts and pins float and you skim them off.

When they say stamp the ingots, they mean for investment ingots.

What you want to do are pigs.

Kinda of like Tin and Tin. 2 different things.

You have a lot to learn about aluminum and her many alloys.

Extruded aluminum is a type of metal when electrically heated softens like putty, the putty is forced through a die to give it shape. Extruded is designed to stiffen very fast leaving the die, no good to use as a casting metal.

And this is one of the many reasons why your whisky glass mold did not properly completely fill, the alloy used was designed to quick freeze..

Hydraulic pumps and transmission cases are made from an alloy having resistance to abrasion.

Larger aluminum castings such as cylinder heads and engine blocks have a slow freeze rate which allows the mold to completely fill.

Aluminum used for outboard engines has a high copper content which inhibits corrosion, sheet aluminum used to build boats and other items found in marine use will also have a high copper content but must remain easy to weld.

If you were able to guarantee the purity of your ingot you could look outside of the scrap area for a buyer.

You could not spin cast aluminum into a new shape.
