I don't suppose anyone knows a good supplier of aluminium around the North West (or anywhere UK)? I'm trawling through websites and yell.com here, and drawing a lot of blanks trying to get 6160 T6 or similar grade in sheet form. Some sites don't quote a grade so I'm presuming its pure aluminium.
I also joined the club today. I take it that paypal automatically includes your address with your payment, as I wasn't asked for one during the process.

Best,
Steve

I very much doubt alumimium sheet would be pure aluminium, unless it has specialist uses - maybe architectural, because of its better corrosion resistance. Most likely to be 6061/3 or 6082 T6 (Used to be called HE30). 2014 T6 (HE15) is much stronger but hard to bend and you can't weld it.

If you want small quantities it is always worth trying local engineering or fabrication companies - they may sell you offcuts.

I asked Fiona (membership sec.) about your Paypal question. She's not sure but Heather should know

How Do Steve; and welcome Thumbs Up
Don't quote me on this; but I think paypal does include an invoice address to the merchant.
 
I have bought several lengths of aluminium, in flat bar, tube, angle and rod from
http://www.metals4u.co.uk/ in the past, the grade was 6063 or 6082  depending on what stock is available, I seem to remember that the 6082 has been seen to replace the 6061 alloy. you can find data sheets on the site, or I can email you them if you cant find them.
 
All the material was clean and quickly delivered.
 
I used the flat bar for making truck brackets on one of my custom long distance pumping skate boards,  it was easily cold formed and has put up with many miles of repeated flexing and vibration under load and and still going strong after 2 years, (maybe relevant or not as the case may be)
 
I hope this helps?
 
What'cha making?
 
Take  care,
Barry ;-)

Thanks all.

Re: the address, I found and used the enquiries@bhpc.org.uk email shortly after I posted on the forum and Heather got back to me very quickly. As you say, Paypal does include the address and I had actually sent the wrong address (I've only used it once before and that was a year ago) but all sorted now.
Thanks for the heads up about HE30 and 15, Geoff. I did notice this on my internet travels but hadn't heard the terms before. I saw a few references to various 1000 grade aluminium which I understood was virtually pure aluminium.
I had seen metals4u, Bazz, but I couldn't find what grade they were selling. But I've just found the data sheets right at the bottom of the page under 'technical' in tiny writing. 6082/3 looks good, so thanks for the pointer.
I've several recumbent designs on the drawing board with a view to using pop riveted aluminium. I'm going to start with a basic swb rear drive for simplicity. I'm doing a wooden mock first to get the sizing right. Perhaps I can get some photos up next week.
I'm also looking at a monocoque aluminium design that can be sat within as a streamliner. This monocoque can provide roll / crash protection and need not be streamlined. A two part, single join vac formed jacket that fits over it could then give a more idealised aerodynamic profile. I'm wondering if this might prove to be easier than a carbon / kevlar / fibreglass approach. It might also allow for different profiles to be experimented with without too much hassle. Maybe, haha.
I'd also love to try building a pop riveted Velocraft NoCom clone. Its such an irresistibly lovely looking machine (pipe dream).
Getting some aluminium through the door will be a good start.

Best,
Steve.

Hi Steve,
                you could try www.aluminiumwarehouse.co.uk who are very helpful,deliver quickly,various grades available sheet/bar/extrusions
or
for  higher strength[aircraft grade] www.pfametals.com though these are obviously more expensive.
 I have used both suppliers many times with no complaint
