Greyman 27,432 Posted March 10, 2021 Report Share Posted March 10, 2021 Anyone know how magnesium compares to other metals like copper and brass in the world of scrap, rough price per kilo or metric ton ??? Quote Link to post Share on other sites
South hams hunter 8,906 Posted March 10, 2021 Report Share Posted March 10, 2021 im not sure theyll take it, cant find a price for it anywhere Quote Link to post Share on other sites
Daniel cain 44,594 Posted March 10, 2021 Report Share Posted March 10, 2021 think you would have to take it to a specialist for the best price.... Maybe someone who deals in telecoms waste etc Quote Link to post Share on other sites
chartpolski 22,626 Posted March 10, 2021 Report Share Posted March 10, 2021 Magnesium alloy is used extensively in aircraft. We did training to combat magnesium fires as it reacts differently and needs specialist fire fighting equipment. Ordinary fire extinguishers and even water can make a magnesium fire worse ! So, I'd guess ordinary scrap dealers aren't trained or equipped for handling it, especially with Health & Safety regulations. It would have to be a specialist operation. Cheers. 1 Quote Link to post Share on other sites

They stick ingots of it to the bottom of steel boats in fresh water, it’s sacrificial and is attacked by corrosion to stop the hull rusting, 1 Quote Link to post Share on other sites
Arry 20,616 Posted March 10, 2021 Report Share Posted March 10, 2021 Do you know for sure they are magnesium mate? As some Sacrificing Anodes are Aluminium some are Zinc and some are Magnesium. Cheers Arry 1 Quote Link to post Share on other sites

Cheers Arry Not an 100% mate but I,m sure it’s the main ones on narrow boats, have a job to start next week blacking the bottoms in a boatyard so will have to clean them and remove the old anodes first was just looking for a little cash side line if they are worth collecting Quote Link to post Share on other sites

mushroom 12,672 Posted March 10, 2021 Report Share Posted March 10, 2021 Magnesium... loads of fun and highly dangerous when it ignites You had better check with the UK waste laws. I can't see it being legal to store, process etc without specialist licenses. Obviously I'm talking about pure or very high grade alloys, not alloy wheels lol 1 Quote Link to post Share on other sites

Cheers Arry We use sacrificial anodes to lay groundbeds which we attach to high pressure steel gas mains.My pal lit a fire in a skip in his yard without realizing one of the lads had thrown a couple of snapped anodes in it.He reckons the went off like f**king bombs. 2 Quote Link to post Share on other sites

Seem to remember there was something about the Mag anodes on Alpha Piper, that made the whole thing 100 times worse for the fire crews. 1 Quote Link to post Share on other sites

Obviously I'm talking about pure or very high grade alloys, not alloy wheels lol They look like this mate and the bigger the boat the more of them there are, people change them when they have the underwater part of the boat painted and as it’s an every 4 year job there is often loads of meat left on them when they get changed so recon if I,m doing a couple of boats a week may build up some good weight, if it’s sellable Edited March 10, 2021 by Greyman Quote Link to post Share on other sites
