Additional Introduction

Aluminum Alloys Naming Rules

Usually, the naming of international grade aluminium alloy consists of four digits plus status code (one letter plus several digits).

For example: 6 0 6 1-T 6 5 1

The specific meaning is as follows:

First digit:

The main alloying elements are coded as follows:.

1: Pure aluminium, aluminium content not less than 99.00%







8: Other Elements

9: Standby group

Second digit:

Indicates the control of the limit content of alloying elements or impurities.

0: indicates that there is no special control on the limit content of impurities

1-9: indicates special control over the limit content of one or more single impurities or alloying elements.

Third and fourth digits:

Pure aluminum (the first place of the brand name is 1) : represents the two places after the decimal point in the lowest aluminum percent content, such as 1050 aluminum content of 99.50% other alloys (the first place of the brand name is 2~9) : the two Numbers have no special significance and are only used to identify different alloys in the same group, and the second place represents the modification situation. If bit 2 is 0, it is the original alloy. If it is 1-9, it is indicated as modified alloy

Fifth digit:

Basic status code (GB/T16475-1996)

F: Free processing state, suitable for processing products in the forming process without mechanical properties requirements;

O: Annealed state, with 1 digit Arabic numeral except 0 affixed

H: Work hardening state, suitable for products that increase strength by hardening (this product can reduce some strength by heat treatment), often suffixed with more than two Arabic digits;W: in the state of solid solution heat treatment (an unstable state), it is only applicable to the alloy with natural aging at room temperature after solid solution heat treatment.Such as, W 1/2 hours

T: Stable state (different from F, O and H) after heat treatment. It is suitable for products with stable state after heat treatment (which can also be hardened by work). The letter T is always affixed with more than one Arabic numeral.
