Definitions

the aluminum strip produced according to the invention has, on the one hand, very good properties with regard to electrochemical roughening of the strip and, on the other hand, improved mechanical properties, in particular after a stoving process has been carried out.
This is all the more surprising since the experts have previously believed that only an Fe content of max. 0.4% by weight may be present in an aluminum strip for lithographic printing plate supports in order not to lead to uneven roughening of the strip due to coarse precipitation phases in the cast, which are preferably attacked during electrochemical roughening.
the elimination of coarse phases in the cast does not occur in the aluminum strip produced according to the invention, since a uniform roughening structure is achieved during the electrochemical roughening.
the aluminum strip according to the invention has an elastic limit Rp0.2 of at least 180 MPa and a tensile strength Rm of at least 190 MPa in the rolling direction and / or an elastic limit Rp0 , 2 of at least 190 MPa and a tensile strength Rm of at least 200 MPa transverse to the rolling direction at room temperature.
the aluminum strip produced according to the invention has a heat treatment of 240 ° C for 10 min. a yield strength Rp0.2 of at least 140 MPa and a tensile strength Rm of at least 150 MPa across or in the direction of rolling, the aluminum strip produced according to the invention is particularly suitable for lithographic printing plate supports for particularly long runs, since these lose as little strength as possible after the baking process should.
the aluminum strip produced according to the invention is further improved in that the alternating bending strength of the aluminum strip in the rolling direction is more than 3000 bending cycles, preferably more than 3200 bending cycles in the rolling direction.
the above-mentioned number of bending cycles in the rolling direction is achieved by the aluminum strip produced according to the invention, in particular in the hard-rolled state, and thus exceeds conventional ones Aluminum strips in hard-rolled condition clearly.
the flexural fatigue strength was measured by taking samples with a length of 100 mm and a width of 20 mm from the aluminum strip, the longitudinal axis of the samples corresponding to the rolling direction. The samples were then subjected to an alternating bend over a radius of 30 mm and the number of bends to break was determined.
the number of bends is a measure of the stability of a printing plate carrier made from the aluminum strip during the printing process. In the present case, the number of bending cycles was statistically determined from twelve samples.
the aluminum strip produced according to the invention thus enables the production of printing plate carriers with a particularly long service life.
Aluminum strips in condition H18 were also produced from the melts V486 and V488, with intermediate annealing taking place during cold rolling.
the degree of rolling down to the final thickness was limited to 65% to 85% after the intermediate annealing.
