Aluminum circle

«The reverse side of the medals usually are very similar». B. Grzegorczyk.

Production

According to GOST 21 488−97 — aluminium circle is made of round section Ø mm 8−400, from technical aluminium AD0, AD1, HELL or alloy AK8, AMC, AD31, AK6, 1, AK4, AK4−1, D16 or other. Standard length is 0.5−6 m. the Chemical composition of normalizes GOST 4784−97. The circle with the usual quality of finish has a matte surface with no delamination, cracks, foreign inclusions, traces of dirt or corrosion. The microstructure of the parts that have been hardened without any traces of stratification. The trials they undergo on completion of heat treatment. Cosine Reza, ovality, twist and curvature tested according to GOST 26877−91.

Packing, storage, transportation and temporary protection products normalizes GOST 9.510−93.

Dignity

Aluminum circle is very light, relatively cheap, well machined. It is non-magnetic, has high electrical and thermal conductivity. Due to the surface oxide film, it is a little susceptible to corrosion in a damp environment. It is non-toxic, durable, aesthetically appealing, For a number of properties of aluminium is superior to steel:

• is much easier to metal;
• much more technical;
• alloys of aluminum with silicon or magnesium, racks, even in sea water

Marking of aluminum circle

Hot-deformed circle is produced without heat treatment.

Example of designation of aluminum circle: Circle D16T PP КР60Пх4000 GOST 21 488−97 Round alloy D16, manufacturing high precision, sealed and naturally aged, a diameter of 60 mm, high tensile strength, length 4000 mm:

Duralumin circle

Circle marks D16, D16T, B95T1, B95 — GOST 21 488−97 made from aluminum (chem.composition — GOST 4784−97). Due to the doping (additives of Cu, Mg, Mn) dural has considerable fatigue endurance, static strength up to 500 MPa, viscosity. Compared to steel, duralumin easier and cheaper. Additional heat treatment (hardening, natural or artificial aging) helps to strengthen this circle. Since duralumin products are subject to corrosion, they make a film of pure aluminum.

Use

Dural relevant in transport engineering when creating lightweight durable frame structures for sports cars, ships, aircraft,
