Other than purely by weight......is there any other way of telling the difference between an alloy and a steel bonnet??

Purely for car breaking/ebay purposes....

Trying to decipher if this guy has an alloy bonnet- it is from an imported STI so it SHOULD be....but you never know in some cases (or if infact he really does have an STI!!)

Cheers,
Chris

Yes, stick a magnet on it or try to, if alloy then it will not attach, use some magnetic (kids) alphabet type letters the sort you see on fridge doors and that will work.

These also work for spotting filler/repair work on cars especially areas like wheel arches

if no magnet you can tell with the weight they are well light.

The Zohan

Agreed. However, if the owner is not sure about how light, light is then the magnet will confirm one way or the other and leaves no room for error or guess work

Cheers guys- I would obviously be able to tell by the weight but the guy breaking isn't sure how light "light" is.....

I will get him to try a magnet on it and see

Failing a magnet, tap it. My alloy one doesn't resonate like my old Scoobs steel one. Almost sounds a bit plasticky!

Took 2 people to remove my steel bonnet (bl**dy heavy) & just one person with one finger to put the alloy one back on ... it's a big difference & certainly noticeable.

Obviously it would be lighter being alluminum although this is a little ambiguous being there is not an alternative bonnet manufactured in the other material to compare it to

The magnet leaves no room for doubt whatsoever it sticks to steel and falls straight off of alloy when released.

You'd need to be one dumb motherf*cker to be unable to fathom the difference between one finger & 2 people

yes - if it is attached to a uk car the it is steel

Perhaps with a magnet then

PS

Apparently alloy bonnets float on larva hence another potential source of checking ...

The Zohan

Only if you constantly cool them with water or they melt in a fraction of a second, same is in fact true of steel bonnets although the alloy should melt quicker but how much quicker i wonder, still not a definite test.

I'd stick (or not as the case may be) with the magnet

Unless it has been swapped of course. And apparently it's from an import so should be alloy.

The magnet is the best test as far as I know.

The lightness test is also pretty comprehensive

alloy one's suck,they wobble and vibrate and look like they might fly up when moving at at a lick,i took myn off and swapped for a steel one.
Besides when you,ve got a car with 300 plus BHP,what difference is afew kg's more going to make
ps and there cheaper
