Aluminium Alloy Numbering System
Wrought aluminium alloys use a 4-digit system. ANSIAA The Aluminum Association.
Energy America Eap 440w Mono Made In The Usa 30 Panels Per Pallet
Temper Designations for Heat Treatable Alloys A new wider range of special tempers having up to four digits after the T have been introduced for non-standard applications eg.
. The most accepted naming system created by the Aluminum Association ANSIAA has two nomenclatures for these alloys and groups them into families based on the primary alloyed metal. Chemical Compositions Please refer to the datasheet entitled Aluminium Specifications. 1000 series 2000 series 3000 series up to 8000 series see table 1.
The UNE system of naming aluminum is similar to ANSIAA system. Wrought Alloys A four-digit system is used to name wrought composition families. Specified mechanical property steels.
UNS and the Aluminum Association AA parallel each other in their. These are grouped based on their primary alloying elements. AISI and SAE carbon and alloy steels except tool steels H00001 to H99999.
Aluminum and aluminum alloys. The alloying system for aluminum uses a rational numbering system. Copper 2xxx Manganese 3xxx Silicon 4xxx Magnesium 5xxx Magnesium and silcon 6xxx Zinc 7xxx Other elements 8xxx Unused series 9xxx For the 2xxx through 7xxx series the alloy group is determined by the alloying element present in the greatest mean percentage.
The first digit Xxxx indicates the principal or major alloying element which has been added to the aluminum alloy and is often used to describe the aluminum alloy series ie. The Aluminum Association Casting Temper Designation System see above chart uses letters and numbers to indicate the major types of thermal treatments applicable to engineered castings. Rare earth and rare earthlike metals and alloys.
Wrought Aluminum Alloy Designation System Wrought alloys have a 4-digit number system. China Aluminium Alloy Numbering System Aluminum Grade Aluminum Sheet Coil Find details about China Hot Rolled Coil Aluminum Manufacturer from Aluminium Alloy Numbering System Aluminum Grade Aluminum Sheet Coil - TRADEMATT HENAN INDUSTRY CO. Indicating the aluminium alloy with the exception of the 1XXX series.
ALUMINUM ASSOCIATION numbering system for wrought and cast metals. Soft O temper is now classified H111 and an intermediate temper H112 is introduced. For alloy 5251 tempers are now shown as H32H34H36H38 equivalent to H22H24 etc.
Heres a list of the most used designations used around the world. Similar to the wrought aluminium alloy designation system the second and third digits for these grades are used to indicate aluminium purity above. First Digit A An alpha indicator of base metal.
The alloying system for aluminum uses a rational numbering system. Aluminum l 9900 1xxx Aluminum alloys grouped by major alloying elements. For example AA designates A3560 UNS uses A13560.
Each name begins with AA followed by four numbers. The format of this system consists of a one-letter prefix A for aluminum followed by five digits. AISI and SAE H-steels.
Aluminum Alloys Naming Convention. Letters used in the unified numbering system are A for Aluminum and Aluminum alloys C for copper and copper alloys D for specified mechanical property steels E for Rare earth and rare earthlike metals and alloys F for cast Irons G for AISI and SAE carbon and alloy steels H for AISI and SAE H-steels J for Cast steels K for Miscellaneous o. 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.
Ad Great Prices on our Quality Aerospace Aluminum. UNS UNS stands for Unified Numbering System it is a unified identification for metals and alloys of metals popular in the United States. UNS and the Aluminum Association AA parallel each other in their numbering system.
The first digit is used to designate the primary alloying element. The UNS system breaks down as follows using A13560 as an example. Prepared by Rick Shuster.
1612021 The second and third digits of the cast aluminium numbering system are also arbitrary. F as-cast O annealed T4 solution treated and aged T5 precipitation hardened T6 solution heat treated quenched and precipitation hardened. H19H22 H24 are now shown separately.
The alloys are designated by a single letter prefix followed by a four digit number specifying chemical composition. As an example a 1XXX alloy indicates a mostly pure aluminium alloy whereas a 6XXX alloy indicates that significant amounts of magnesium and silicon have been added to the aluminium. Copper and copper alloys.
This alloy designation system stands for Unified Numbering System and is a designation system for metals and alloys widely accepted in North America. The unified numbering system UNS is an alloy designation system widely accepted in North America. Alloy Numbering System No Change.
UNS and the Aluminum Association AA parallel each other in their. Log into your account. Aluminum Numbering System The alloying system for aluminum uses a rational numbering system.
