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.

4032 aluminium ialah aloi aluminium 4000 siri. Penambahan pengaloian utama ialah silikon. Sifat yang dipetik adalah sesuai untuk perangai T6. Untuk mencapai kemarahan ini, logam itu dirawat dengan haba dan dibuat secara buatan sehingga ia memenuhi keperluan sifat mekanikal piawai. 4032 ialah sebutan Persatuan Aluminium (AA) untuk bahan ini. Dalam piawaian Eropah, ia akan diberikan sebagai EN AW-4032. Selain itu, sebutan kimia EN ialah AlSi12,5MgCuNi. Penamaan British Standard (BS) ialah DTD324B. Nama AFNOR (Perancis) ialah A-S12UGN. Dan nombor UNS ialah A94032.

Ia pada asalnya menerima penamaan standardnya pada tahun 1954.

Ia mempunyai kekuatan tegangan tertinggi antara aloi 4000 siri dalam pangkalan data.

Bar graf pada kad sifat bahan di bawah membandingkan aluminium 4032 dengan: aloi 4000 siri (atas), semua aloi aluminium (tengah), dan keseluruhan pangkalan data (bawah). Bar penuh bermakna ini ialah nilai tertinggi dalam set yang berkaitan. Bar separuh penuh bermakna ia adalah 50% daripada yang tertinggi, dan seterusnya.
