CODE DESCRIPTION OF METALLURGICAL STATES OF PRODUCTS SUPPLIED BY ALUTITAN S.P.A. (UN EN 515-'96)

Alloy codes for basic metallurgical states of the products are given by letters. In case further subdivisions of such states are necessary, such subdivision are indicated by one or more numbers placed after the letter indicating the basic metallurgical state. These numbers refer to a specific sequence of treatment operations, but the only treatments which have a significant influence on the product properties are indicated. In case a new or different version of the same sequence of basic operations is applied, and it determines new or different properties in the same alloy, additional numbers will be added to the alloy code.

F - Manufactured Raw
This code applies to semi-finished products deriving from such plastic transformation processes (extrusion), where no control on thermal or strain hardening conditions is exercised. For such state, no limit values for mechanical properties are specified.

T - Heat-Treated To Produce Stable States Other Than F
This code applies to semi-finished products which undergo thermal solution treatment, with or without supplementary strain hardening, in order to produce stable metallurgical states. The letter T is always followed by one or more numbers, each one referring to a specific sequence of treatments.

SUBDIVISION OF CODES OF T STATE

First Number After T
The first number after T is used to identify specific sequences of basic treatments. Number have been given as follows:

T1: Cooled after hot plastic processing and naturally aged to a substantially stable condition. T1 applies to semi-finished products that are not subject to plastic cold deformation, once they have cooled after a hot plastic processing; or to semi-finished products in which the effect of plastic deformation resulting from flattening or straightening may not be reflected within the limits of mechanical properties.

T5: Cooled after hot plastic processing and artificially aged.T5 applies to semi-finished products that are not subject to plastic cold deformation, once they have cooled after a hot plastic processing; or to semi-finished products in which the effect of plastic deformation resulting from flattening or straightening may not be reflected within the limits of mechanical properties.

T6: Solution heat treated and artificially aged.T6 applies to semi-finished products that are not subject to plastic cold deformation, after a solution treatment ; or to semi-finished products in which the effect of plastic deformation resulting from flattening or straightening may not be reflected within the limits of mechanical properties.

The 6060 series alloys attain the same mechanical properties here specified, with both oven solution treatment and cooling after a hot plastic processing (extrusion), at a rate sufficient to keep the constituents of the alloy in solid solution. Alutitan applies such code to products for which mechanical properties must be guaranteed according to agreements or contracts, and be kept inside maximum values tolerances set up as standards and applied by general norms.
