For unalloyed grades, the designation shall be in accordance with EN 576. 5.3 Temper designations The following abbreviations shall be used as temper designations for the conditions of heat treatment, referred in Tables 2, 3 and 4 and Table A.1: F as cast; O annealed; T1 controlled cooling from casting and naturally aged; T4 solution heat treated and naturally aged where applicable; T5 controlled cooling from casting and artificially aged or over-aged; T6 solution heat treated and fully artificially aged; T64 solution heat treated and artificially under-aged; T7 solution heat treated and artificially over-aged (stabilised). NOTE For aluminium casting alloys, solution heat treatment involves quenching from elevated temperatures and distortion may occur. 5.4 Casting process designations The following abbreviations shall be used as designations for the different casting processes: S sand casting; K chill or permanent mould casting; D pressure die casting; L investment casting. 5.5 Designations to appear on drawings The complete designation of the casting shall appear on the drawings being part of the order information.

EXAMPLE EN 1706 AC-42000-K-T6 is the complete designation of the alloy EN AC-42000, chill cast solution heat treated and fully artificially aged. 6 Chemical composition 6.1 General Chemical composition shall be expressed in accordance with the writing rules given in EN 1780-3. The chemical composition of aluminium casting alloys shall be in conformity with the limits specified in Table 1. NOTE Table 1 also includes the chemical compositions of ingots used to produce castings. These are shown in brackets where they differ from the casting limits and are taken from EN 1676. When specified, analysis of elements for which specific limits are given in Table 1 shall be carried out. Analysis for other elements shall be carried out only when agreed between supplier and purchaser. This particularly applies to modifying or refining elements such as sodium, strontium, antimony and phosphorus. Alloying elements and impurities shall be expressed in the following sequence: silicon, iron, copper, manganese, magnesium, chromium, nickel, zinc, lead, tin, titanium, other elements each/total, aluminium. Additional specified elements with specific limit shall be inserted, in alphabetical order with respect to their chemical symbols after titanium, or be specified in footnotes. 6.2 Samples for analysis When samples are required for analysis by emission spectrometry, they shall be taken from the melt at the time the castings are made and shall be cast into a metallic die. NOTE If analysis by emission spectrometry is carried out on a casting, it is recommended that a part of the casting is remelted and cast into a metallic die to minimize the unavoidable segregation effect. The level of certain elements such as sodium, strontium and magnesium, is normally reduced by the remelting, and analysis for such elements should be made directly on the casting. For sampling and analysis, the use of existing rules or standards is recommended until a suitable European Standard is published. SIST EN 1706:2010

Nevertheless, the minimum and maximum content of
refining elements shall be agreed between the manufacturer and the purchaser. i These alloys are in compliance with EN 601 (for information only). j Minimum Ti limits are not required if the grain refining is not required or reached by other means.

EN 1706:2010 (E) 13 7 Mechanical properties 7.1 General The minimum mechanical properties for separately cast test pieces for sand cast, chill cast, investment cast and pressure die cast processes shall be in accordance with Tables 2, 3 and 4. For each alloy, mechanical properties are only specified for the commonly used methods of casting and for commonly used tempers. For other processes and tempers, characteristics shall be agreed between supplier and purchaser. NOTE 1 The mechanical properties of pressure die castings are very dependent on injection parameters and the properties in Table A.1 are for guidance only. NOTE 2 For F temper, the values specified in Tables 2, 3 and 4 can be eventually obtained only after holding a few days at room temperature.
