Wheel balancing weights
« on: 13 October 2009, 17:13:27 »

Had to go and have a puncture repaired yesterday. While I was waiting I read a notice on the wall stating that due to new regulations lead balancing weights are no longer allowed and have been replaced by zinc based ones. As the cost of zinc ones are considerably higher they have no alternative but to pass this cost onto the customer. WTF :o when you think about the amount of lead that has been and will be used in industry, constuction and manufacture, in the grand scheme of things I fail to see what difference to the environment lead wheel balancing weights will make.

Lead and other toxic chemicals have been being reduced/banned in new products for quite some time now.  If you've seen the ROHS-compliant lables on electrical goods it means that lead-free solder has been used apart from other things.

Lead balance weights are likely to get quite a lot of lead into the environment especially when people kerb their wheels and the whole lot ends up down a drain.

I have a friend who sells balance weights and there is another problem with Chinese ones apparently.  They quite often break apart which can be quite dangerous at speed, not least because of the missile it produces!

I wonder if the government intend not to use lead in all the new nuclear power stations that they intend to build ::)

No, they'll line the reactors with Scousers, it'll be thick enough! ;D

Indeed RoHS6 regulations mean no Lead, Mercury, Cadmium, Hexavalent Chromium, PBB, or PBDE allowed.

(RoHS 5 covers all the above with the exemption of lead as per some specialist industry exemptions including Telecoms equipment as of today)

Only really relevant to chemicals, not actualy to difficult to comply with either (it puts most of the emphasis on manufacturers registering the substances)

I'll have to use my lead solder sparingly then. The one I'm using has only lasted 30 yrs so far!  ;D  ;D  ;D  ;D

Zinc is used a lot in boating as a sacrificial anode as it corrodes easier than most metals.... I see alot of money being made from replacing zinc weights, especially during wetter seasons.   >:(

Zinc is cheaper
