1CR21AL4 Aloi Aluminium Kromium Besi Diameter Besar
Aloi besi-kromium-aluminium berdiameter besar 1CR21AL4 mempunyai kandungan kromium antara 17.0% hingga 21.0%. Dalam persekitaran kromium tinggi, filem oksida yang terbentuk pada permukaan aloi bukan sahaja dengan ketebalan sederhana tetapi juga mempunyai kerintangan yang sangat tinggi. Filem ini mempamerkan kadar penghijrahan ion yang sangat rendah pada suhu operasi berterusan maksimum 1100°C, dengan berkesan menghalang degradasi oksidatif substrat logam selanjutnya. Cabaran pemprosesan untuk bahan berdiameter besar terletak pada tegasan dalaman semasa lenturan. 1Cr21Al4 mengekalkan kadar pemanjangan melebihi 12%, membolehkan jurutera memproses wayar tolok berat menjadi gegelung berdiameter besar berbentuk U, beralun atau heliks tanpa penyepuhlindapan perantaraan yang kerap.
