boshlangan eng asosiy brazing materiallari - AGCU7.5, AGCU25, AGCU28,AGCU55 va boshqalar va AGCU28 AGCU28 keng qo'llaniladi. Ular yaxshi o'tkazuvchanlik, ravonlik va namoyon bo'lishadi va elektr bo'shlig'ida keng qo'llaniladi. Uzoq haroratda uzoq muddatli yukning yuqori qismiga nisbatan past qarshilik tufayli, uning harorati 400ºC dan past bo'lgan qismlar uchun mos keladi.
Tangalar va bezaklar sifatida ishlatiladi. Tanga sifatida ishlatiladigan qotishmalar AGCU7.5, AGCU8,AGCU10va hokazo; bezak sifatida ishlatiladigan qotishmalar - bu AGCU8.4, AGCU12.5 va boshqalar
