Aluminium Alloy Numbering System. Since the International Designation System for Wrought Aluminum and Wrought Aluminum Alloys is based on USAs national standard American National Standard Alloy and Temper Designation System for Aluminum ANSI H351 the system limits introduction of experimental alloy compositions to USA registrations. The unified numbering system UNS is an alloy designation system widely accepted in North America. For example Aluminum 6061 AA6061 is assigned UNS A96061. For example A for aluminum C Copper and Copper Alloys Z Zinc and Zinc Alloys etc.
The alloying system for aluminum uses a rational numbering system. Each UNS number relates to a specific metal or alloy and defines its specific chemical composition or in some cases a specific mechanical or physical property. An experimental alloy registered by USA under this system is indicated by the prefix X. Overview of the UNS system This is an overview of the UNS system with special emphasis on common commercial alloys. 9 Zeilen What is the Aluminum Numbering System. The most important cast aluminium alloy system is AlSi.
The first digit indicates the alloy group.
In most cases the letter is suggestive of the family of metals identified. No major alloying additions 2xxx Copper 3xxx Manganese 4xxx Silicon 5xxx Magnesium 6xxx Magnesium and silicon 7xxx Zinc 8xxx Other elements eg iron and silicon 9xxx Unassigned Understanding Wrought and Cast Aluminum Alloys Designations 25. It consists of a prefix letter and five digits designating a. The unified numbering system UNS is an alloy designation system widely accepted in North America. Wrought Aluminum and Aluminum Alloy Designation System A four-digit numerical designation system is used to identify wrought aluminum and aluminum alloys.
