5XXX and 6XXX sheet aluminum alloys may be produced from proprietary alloy compositions. Each family shares similar characteristics, but each alloy retains unique features. For example, AA6022 has the strength of AA6111 and the formability of AA6016A, but may be more costly since the low copper and low iron requirements make it difficult to produce from recycled stock. Certain alloys may be available only from specific companies, and may be marketed under trademarked names – such as Advanz (Novelis), Superlite (Aleris), or Surfalex (Constellium).
