1. A method for producing a satinized surface on an aluminium substrate, comprising the method steps:providing an aluminium substrate; and
treating by a blasting process with a blasting material the surface regions of the aluminium substrate provided that are to be satinized;wherein there is used as the blasting material a mixture of angular and spherical particles having a grain diameter D90 of ?0.3 mm, further wherein the mixture has the following distribution:particles with a diameter >0.315 mm being <0.1% of the total mixture;
particles with a diameter ?0.315 mm and ?0.200 mm being ?5% of the total mixture;
particles with a diameter <0.200 mm and ?0.050 mm being ?95% of the total mixture; and
particles with a diameter <0.050 mm being <0.1% of the total mixture.
