Aluminum circle d. 65 mm brand B95
High-strength aluminum circle
Weight 1 m. = 9.45 kg. Minimum order 20 kg.
The mechanical properties of aluminum are low, so aluminum alloys are actively used, they are conditionally divided into deformable and cast.(//tractor-service.com)
Casting alloys are marked with the letters AL (AL2, AL4, A9 - silumins).
They, in turn, are divided into alloys that are hardened by heat treatment and alloys that are not hardened by heat treatment.
Joints not hardened by heat treatment have excellent plasticity. Such alloys include АМц, АМг2, АМг3, АМг5, АМг6 - supplied both in a soft and semi-hardened state: for example, АМг3М, АМг3Н.
Dural, avial, alloys for forging, and high-strength alloys are among the heat-hardened alloys. Avial alloys are marked AB, hardened and cooled in water.
