Very little difference since it is 2 carbon iron alloys, in other words 7.4 to 7.8 for cast iron and 7.8 for steel.

Hello,
You can still weigh down the water,
You fill a fleet and add 100 kg of salt is easy to fill and empty and in addition it is antifreeze.

you get 300 kg for 200 liters
We do this to ballast the wheels of the loaders!

: Cheesy: you forgot the data of the problem:
Harry wants 100 kg for 10 liters. :!:
Well, you have to recover old car batteries, break them, and take the lead.
By cons I have no solution to properly remove the acid from the batteries. :?

Hi Harry, it's a little lighter than steel, around 7 Tons / m3.

Here is what you will like:

Tungsten tell you? Otherwise, tantalum and uranium are reaching out to you : Cheesy:

The history of salt, lead recovery or pouring concrete is a good idea.

Thanks for these informations.

For lead recovery, watch out for battery acids.

cast iron is a little bit less dense than steel

cast iron is practical for a builder who will mold his counterweight to the desired shape

I prefer to walk around a metal merchant and choose what I like: the sheet metal drops are very practical: we can stack the number of pieces it takes to make the exact weight without losing space

in old batteries the acid is completely lost by fesing lead sulphate ...

if the battery is not old enough just pour this acid on a pile of limestone and it makes calcium sulfate = plaster therefore harmless

the problem is not acid but lead: solid lead is not polluting because it is unalterable and does not disperse: but the lead compounds which are in a battery fall in dust and disperse everywhere

no need to melt batteries to make solid lead: a very small part of the lead will melt correctly: for the rest you have to do real metallurgy ....

Hello harry the delighted

You have another possibility, at the junkyard, they sort the metals. I have already seen a 200 liter barrel filled with carbide pellets (cutting tools for lathes and milling machines). It is a sintered "alloy" containing a very large proportion of Tungsten (density in the 19!).
For your problem, for example, you can make a composite concrete / carbide pad. By cons, no idea of ​​the price by weight that the scrap dealer will ask you .... : Mrgreen:
