I am looking for 2 sections Mild Steel plate. I can get Alu tooling plate but its too expensive.
Looking at roughly 485 x 340 x 50mm. I'm not looking for a massive plate so cant buy from places like Parkers etc. Anyone able to help?
Thanks

50mm thick is hardly a plate - nearest that size in ground was £539
Good luck

Getting a 50mm thick section that small might be a problem. Never seem 50mm plate in smaller than 4 x 2 mts. If you have a local profiler or supplier you might want to try them to see if they have any offcuts.
It will weight around 70KGs though.
What is plate then? The only 'definition' I know is from Click Metal where I tend to buy from. Anything sub 6mm is typically sheet, more is plate. Anyways, lets not get hung up about terminology.Quote:

Chaz have you thought about casting them in Aluminium then machining flat etc.? Or even having then Cast in Iron or steel.? May work out cheaper or same.
If you want side project the build smelter and cast your own. Few Old alloy wheels or cyclinder heads from scrap yard and your sorted.!!
Id love to but have no kit for it and limited space at the moment. In future if I was making more stuff Id consider that but all I have is a double garage. I'm already using the driveway which has become a mess and a peed off wife. One day when I have my place in the middle of nowhere, Ill be doing that for sure.Quote:

Company I use is closed until Jan. What size and grade do you want me to check on.?Quote:

The tooling plate is a bit more expensive but its fairly flat but if you look at the normal alu (its 6082), you can customise the size / thickness. http://www.clickmetal.co.uk/click-by...luminium-plate for a direct link.Quote:

If you can't source thick plate can you use plug welding through alternating patterns of drilled holes to laminate several thinner plates into a suitably rigid assembly?
You might even get less resonance in a laminated assembly than a single plate?
Just thinking out loud,

Ah ah they want £246 + vat for 920 x 700 x 20mm standard 6082-T6 plate which is last size I bought just before Xmas. Think I paid £187 inc vat for Ground tooling plate.Quote:

That came from ASC metals. Nearist to you is peterborough I think.Quote:

Do they cut into smaller sizes? I dont have tools to cut large sheets, part of the issue. What is the best option for something to cut required sizes from thickish plates (like 25mm)?Quote:

Add further plates in the same way until the desired thickness is achieved, you could optionally weld around the outside,

Last time I did any work on heavy steel plate I had access to Oxy/Gas burning kit, the only thing I have now is my plasma cutter which is only rated for 13mm steel, I suspect you could rent a plasma cutter for a day from a tool hire outfit,Quote:

I've used ASC - good service etc.
Yes ;)Quote:

I'd go with steel if could work with it. However I'd only use it if could do it correctly which means will need heat treating and stress reliefing then grinding in critical places.Quote:

Plug welding will allow thinner plate to be used but all the above still applies and will require more work because all that heat will warp and put stresses into the whole assembly. If those are not released carefully then they will release eventually which will make for bad day when you do realise.!!
I agree with all the points in the previous post, but will also add that the advantages of each material are quite slight, so you might as well pick the easy option and use aluminium.
Yep, this I cant do at home, so looks to me a limited option for me then.Quote:

Thanks. Appreciated. Will take a look. When are you ordering?Quote:

Hope I am doing this correctly.
Plate 1 - L-PNFNN-710-350-30 - This is under this section - EN AW-5052 Equiv. Configurable Aluminum Plates
Plate 2 - L-PNFNN-485-350-50 - also under Alu.
Is it possible to get the top plate (Plate 1) pricing in mild steel too please? I need to machine the Plate 2, so will stick with Alu for that.
I dont strictly need all 6 surfaces milled but it will help with alignment, very curious how nasty the pricing will be. Thanks.
