Is iad Agcu7.5, na príomhábhair prásála a úsáidtear mar phríomhábhair prásálaAgcu25, Agcu28, Agcu55, etc., agus úsáidtear an AGCU28 go forleathan. Mar gheall ar an bhfriotaíocht íseal go hualach fadtéarmach faoi theocht ard, níl sé oiriúnach ach do chodanna prásála a bhfuil a dteocht oibre níos ísle ná 400ºC.
A úsáidtear mar bhoinn agus mar mhaisiúcháin. Is iad na cóimhiotail a úsáidtear mar bhoinn agcu7.5, agcu8,Agcu10, etc.; Is iad na cóimhiotail a úsáidtear mar mhaisiúcháin agcu8.4, agcu12.5, srl
