Rental duralumin tape is regulated GOST 14838−78, chemical composition — GOST 4784−97, the control of structure — GOST 24231−80. The alloy is alloyed with copper (4,4%), magnesium (1.5%) and manganese (0,5%). Copper and magnesium contributes to hardening alloy. Manganese, grinds structure, increases strength and resistance to corrosion. Iron and silicon in the composition of aluminum is an inevitable impurity. Iron is considered a harmful impurity, reduces the strength and ductility. Silicon to a certain extent smoothes the harmful effects of iron. Polonikova tape is marked H2; annealed — M; with normal plating — A. the Tape shall have a flat, smooth surface without defects, cracks, traces burn or stains of pollution. Valid traces of broach.
Heat treatment of the tape optimizes the structure of the material and improves processability. After annealing ВД1АМ becomes more plastic, its easier machining. To increase the elasticity introduced the so called training is rolled with compression up to 5%. Tape ВД1АН2 — polonikova is made with normal plating. This significantly increases corrosion resistance. To improve corrosion resistance may also anodic oxidation.
Duralumin tape differs adaptability, ease of installation, durability, but is inferior to aluminum in corrosion resistance. To correct this, the tape surface planiruetsya pure aluminum. To hardening — heat treatment used. Due to the annealing increases the ductility. Compared to steel alloys, this tape is much easier, cheaper, more simply mounted.
Sealing joints of various designs. Duralumin tape is widely in demand in the housing sector, engineering, construction.
