2. Perangai H12: Keseimbangan Kekuatan dan Kemuluran

Penamaan suhu "H12" adalah penting untuk memahami profil mekanikal khusus bulatan aluminium ini. Dalam sistem H-temper:

• 'H': Menunjukkan pengerasan terikan (Kerja sejuk).
• '1': Menandakan bahawa bahan telah mengalami pengerasan terikan sahaja, tanpa rawatan terma seterusnya untuk mengurangkan kekuatannya (seperti penyepuhlindapan separa).
• '2': Menandakan keadaan "suku keras"., bermakna ia telah bekerja keras untuk mencapai kira-kira satu perempat daripada kekuatan maksimum yang mungkin.

Justeru, 1100-H12 Aluminium Circle mewakili bahan yang lebih kuat dan lebih tegar daripada temper 'O' yang disepuh sepenuhnya, namun masih mengekalkan kemuluran dan kebolehbentukan yang sangat baik untuk pelbagai proses pembuatan. Keseimbangan ini menjadikannya sangat mudah disesuaikan.
