Last Datasheet Revision. Disclaimer. When using an inert gas, it is kwon as MIG process (Metal Inert Gas) and MAG when Metal Active Gas is used. The mechanical strength and ductility of such a casting will be poor and its use limited. The addition of silicon increases the strength of the alloy at the expense of overall ductility. Foundry fluidity of Al with Si or Cu content Elements modifying the eutectic morphology (e.g.Sr), grain refiners (Ti, TiB, etc.) Aluminium alloys (or aluminum alloys; see spelling differences) are alloys in which aluminium (Al) is the predominant metal. 6xx.x Unused series 1xx.xseries Download as PDF. aluminum alloys and is recommended for use before electron optics. 2 THE OXIDE FILM 5 Two classes of alloys may be considered. 6 to pitting. 7Ǣ��B)��0^��#�!e�$E^�4i:�F�-H:ю�,BZ�t ���h����R���|�(Z�_�G\��^N��-Sj���q�r��l��f�˲�=�d���l�,�ӈ����}�{%/�E�#�� �SJ�d��!

About this page. Slow solidification produces a very coarse eutectic structure consisting of large plates or needles of silicon in an aluminium matrix. All aluminium alloys can be coated, provided that the surface is prepared to provide good adhesion, but the corrosion performance achieved with different alloys varies. Aluminium–silicon alloys are the most important of the aluminium casting alloys, and the relevant phase diagram is shown in Fig. ALUMINIUM AND ITS ALLOYS Melting point of Al 6600C Light weight, density is about 1/3 that of steel or copper alloys Certain aluminium have a better strength to weight ratio than that of high strength steel Have good malleability and formability, high corrosion resistance and high electrical and thermal conductivity.

It may seem that coatability automatically means best performance. In each group we shall study the ones which seem the most interesting—those in which aluminium plays an important part. His work, and the gradual realization that hardening arose because of the presence of fine precipitates which provided barriers to the motion of dislocations, is a good example of the transition of metallurgy from an art to a science. 139 0 obj <> endobj xref 139 12 0000000016 00000 n Although normally low strength, some of the more complex alloys can have mechanical properties equivalent to steels. 2xx.x Cu !

The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc.There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable.
