For aluminium products made from some alloys of series 1xxx we propose so called "satine etching" guaranteeing acquirement of beautiful satin finish of aluminium surfaces.
Lmax = 4,0 mb
Smax = 1,0 mb
In case of products made of aluminium seres 2xxx, 7xxx and some from series 1xxx and also for products with damaged surface (scratches, stains) we propose mechanical treatment of so called grit blasting - it is a process consisting of surface treatment with glass balls of various granulation. Limits of dimension:
Lmax = 0,8 mb
Smax = 0,5 mb
Hmax = 0,3 mb
Mechanical polishing we propose for pipes and rods of circular profile and small articles made of pure aluminium or low-alloy materials (series: 1xxx, 3xxx, 5xxx and 6xxx)
Limit of dimension: Omax 80mm
For flat profiles and rods of rectangular cross-section we make milling or brushing lenghtwise. Limits of dimension:
dimension of cross-section - no more than 60 x 60 mm
For pipes and rods of circular cross-section we propose milling or brushing lenghtwise or cross. Limits of dimension:
