Cold-rolled strip and sheet, with high finished product precision, uniform and excellent surface shape, stable and uniform mechanical properties and structure.
Surface finishing of cold-rolled sheet, strip or foil includes bright finishing and matte finishing. In the former, the surface is smooth and brightly rolled on a skin-pass mill, and the surface presents a metallic luster. The latter is matte processing, and the surface is cleaned with weak acid, shot peened or sprayed with alumina particles.
Due to continuous annealing in the atmosphere, the gloss can be controlled by adjusting the crystal grain and thickness, so that the material can be used as roof decoration. Material. Other matte processing can be rolled by rolls with fine asperities.
Titanium foil is made of soft pure titanium, and is produced by cold rolling using the same flat rolling mill. The thickness of titanium foil sold in the market is 0.05mm, which is the minimum thickness of the plate. In addition to pure titanium, there are foils made of beta alloys.
