Aluminum 7075 15 and 20 mm pricing

[Wal]

Blimey - why 7075..? (I know, I know, strength... but really? 7075..? Heh - why not..!)

I buy in small quantities (nowhere near those thicknesses) and find that prices vary quite a bit amongst suppliers - I bought 5 x 4mm sheets (500x150mm) a while back from metalweb for around £100 but the last quote I had (from metalsupermarket) was £37.50 (+ 20%VAT) per 500x200x4mm sheet. Big difference, huh?

Recently I've been using these guys for my 6082: https://www.smithmetal.com/smiths-manchester.htm

(They're happy to supply smaller quantities, 6082 is available in sheet down to a thickness of 1mm, the depot is local-ish and prices are decent - what's not to like?)

You could give 'em a shout and see what they say.

Hi Wal,


Best wishes to all on this great forum.

ot. I am not fully aware of commercial pricing.

Many companies in NL just do B2B.
Since i am still private they will not take orders or do rfq.

Since these parts are to be my Y Z carriage mounting plates .. i do want at least half decent quality parts.

If these plates are to be 150 euros in 6082 or lower strenght and 180 in 7075 .. i rather spend 30 on 7075... it is the weakest link in my gantry..

I dont want to go to heavy so 50kg gantry is about max.. thinner is lighter... well you know... try to do not OTT and spend money where it matters most.

Grtz. Bert.

Hi Bert,

Totally understand your thinking for the sake of an extra thirty Euros... I've found 7075 to be quite a bit more expensive than the 6082 here in the UK, but hey - maybe I'm shopping in the wrong places!

In practical terms, it would be interesting to see how much difference to the strength using 7075 would make...

All the best!

Just ring any aluminium supplier in the Netherlands they will be able to supply tooling plate, it might not be called ecocast but tooling plate is available everywhere I got it in Lithuania in 10 minutes lol and UK 3 of the 4 suppliers in Leicester could get it next day that I rang.

None of the suppliers in Leicester had heard the brand name ecocast but they did know tooling plate, ground flat both sides.

This is an interesting discussion - if a little old. When I looked up the properties, 7075 seemed to be much stronger (tensile strength), but very little stiffer (elastic modulus still around 70GPa) so I didn't see much point in using it - or have I been fed duff data????
