Features and applications:

4000 series aluminum alloy (Al-Si series) typical representative for 4043, 4343 aluminum alloy, specifically for welding materials. 4043 aluminum alloy has the characteristics of low melting point, good fluidity, good corrosion resistance and so on, which is very beneficial to avoid welding cracks. The Si content of 4343 aluminum alloy is higher than that of 4043 aluminum alloy. It has the characteristics of low melting point, narrow solidification range and good fluidity, which is conducive to the reduction of cracks of the reinforcing step when the weld is solidified. It is used as a composite brazing plate coating.

Aluminium 4032 adalah paduan aluminium seri 4000. Penambahan paduan utama adalah silikon. Properti yang dikutip sesuai untuk temperamen T6. Untuk mencapai sifat ini, logam diberi perlakuan panas larutan dan dituakan secara artifisial hingga memenuhi persyaratan sifat mekanik standar. 4032 adalah sebutan Asosiasi Aluminium (AA) untuk bahan ini. Dalam standar Eropa, ini akan diberikan sebagai EN AW-4032. Selain itu, sebutan kimia EN adalah AlSi12,5MgCuNi. Penunjukan British Standard (BS) adalah DTD324B. Sebutan AFNOR (Prancis) adalah A-S12UGN. Dan nomor UNS adalah A94032.

Awalnya menerima sebutan standarnya pada tahun 1954.

Ia memiliki kekuatan tarik tertinggi di antara paduan seri 4000 dalam database.

Batang grafik pada kartu properti material di bawah ini membandingkan aluminium 4032 dengan: paduan seri 4000 (atas), semua paduan aluminium (tengah), dan keseluruhan basis data (bawah). Bilah penuh berarti ini adalah nilai tertinggi dalam kumpulan yang relevan. Bilah setengah penuh berarti 50% dari yang tertinggi, dan seterusnya.
