LONDON, Aug 17, 2011 (Dow Jones) -- The London Metal Exchange Wednesday said it has delisted four brands of the North American Special Aluminum Alloy Contract, or NASAAC, while listing a new aluminum alloy brand.

The delisted NASAAC brands are ALCAN-ALMA, ALCAN-ARVIDA, ALCAN-LATERRIERE and ALCAN - SEBREE, all of which won't be accepted for LME warranting after Nov. 18.

The aluminum alloy brand, JBMI, has been approved under the LME contract with immediate effect.

In addition, the LME said it has approved the change of brand name from ALCAN-BEAUHARNOIS to BHN under the NASAAC.
