主权项 1. A polyamide molding material having the following composition: (A) 27 to 84.99% by weight of a polyamide mixture comprising (A1) at least one partially aromatic, partially crystalline polyamide differing from copolyamide 6.T/6 having a melting point in the range from 255 to 330° C.;(A2) at least one copolyamide 6.T/6 having a content of caprolactam of at least 30% by weight, wherein the sum of the caprolactam contained in polyamide (A1) and copolyamide (A2), amounts to 3 to 30% by weight with reference to the polyamide mixture; (B) 15 to 65% by weight of at least one filling and strengthening agent; (C) 0.01 to 3.0% by weight of at least one heat stabilizer; (D) 0 to 5.0% by weight of at least one additive, wherein the components (A) to (D) amount to 100% by weight, and wherein no metal salts and/or metal oxides of a transition metal of the group VB, VIB, VIIB or VIIIB of the periodic system are added to the polyamide molding material.
