View Full Version : Aluminum foil tape as a substitute for lead?

Question; could I just add on more aluminum tape (ie; double layers) to make up for the lack of weight?

I'm just going to answer this one by showing you the atomic mass of each...

Aluminum: 26.98 Amu
Lead:207.2 Amu

Now you do the math... (no where near as lead, it would take more than 7 1/2 times the amount of Al to make 1 Pb foil) and to add a considerable amount of Al foil would mean a pretty thick stack which would affect how the racquet perform)

Damn. Thanks a lot, though.

Yeah lead is basicly the heaviest thing you can add to to something and is pliable. There stuff out there a bit more heavy but they not metals, they cant be made into foils, and/or were only done in a lab for a few seconds hehe.

Gold and platinum foils while more expensive are still lighter than lead :)

I think you just blew his mind with all that atomic mass stuff.

naaa come on you dont need to know how much an AMU is to realize a bigger AMU means is heavier ;)

A good tip i've heard as a "substitute" for lead tape is using magnetic strips, easily found at Home Depot, etc. Sort of like the peel-away magnets people put on refrigerators.

I asked for those, but no one there knew that the hell I was talking about... would they have a technical name? Like 'magnetic foil tape' or something? And how much does it weigh compared to lead?

I don't know about a "technical" name. I remember seeing that stuff at the HD, though. I'd just ask for "magnet strips with adhesive backing"

Compared to lead, it's probably much lighter/less dense in the same volume, but the strips are much thicker than lead, so square inch for square inch it's probably heavier.

Why not just use lead?

Because I'm trying to find a roll/package of it (all the places near me sell it by the foot) and I thought a hardware store might be a good good bet. Ah well... off to Rackets and Runners, then :)

Also, check golf specialty stores near you, they also use lead tape for customization.

Tried that too... all they've got is lead weights w/ adhesive on them...

Actually, the specific gravity of rolled lead is about 11.5.
The specific gravity of aluminum is 2.64.

So you would need 4 times the thickness of aluminum foil to equal the mass of lead if the area is the same.

To find cheap lead tape, you can usually find it on e-bay for cheap.

Why not just use lead?

thank you...i was banging my head thinking the same thing....
