GOST 2208-91. Tapes brass
Are you interested in GOST 2208−91? Supplier Evek GmbH offers to buy a brass tape at an affordable price in a wide range. We will ensure the delivery of products to any point of the continent. The price is optimal.
The standard specifies the maximum deviations in the thickness of the above assortment of brass sheet metal. On individual positions they are:
|Thickness of foil, mm||Rolling tolerance of normal precision, mm||Tolerance of rolled products of increased accuracy, mm|
|0.05−0.35||from -0.01 to -0.05||to -0.03|
|0.4… 12||from -0.06 to -0.12||from -0.03 to -0.09|
|25 — 150||from -2.0 to -5.0|
Note: the tolerance increases with increasing thickness.
Length of brass bands
|Nominal thickness of brass tape / foil, mm||Length in m, not less than|
The width of the brass foil and tape is in the range of 10 to 1000 mm. Dimensions of brass plates range from 150x600 to 2500x4000 mm (only deviations «in plus» are allowed). Supplier Evek GmbH offers to buy brass rolled products of domestic and foreign production at an affordable price in a wide range. We will ensure the delivery of products to any point of the continent. The price is optimal.
Composition of brass sheet metal
The standard provides for the manufacture of brass tape from alloys of the following grades: L90, L85, L80, L70, L68, L63, LS59−1, LO90−1, LO62−1, LMTS58−2, LVMts59−1-1. By special orders, brass tapes are produced from other grades listed in GOST 15527, in which case the chemical composition of brass is discussed separately.
Mechanical and performance characteristics
- The limit of temporary resistance, MPa — 250… 260 (soft brass), 600… 640 — (solid brass);
- Relative elongation,% — 30… 35% (soft brass), 5… 10% — (solid brass) ;;
- Hardness according to Brinell, HB — 65… 80 (soft brass), 180… 200 — (solid brass).
Delivery status — soft, semi-soft, hard, especially hard (the latter applies only to brass foil). On the surface colors of tarnishing, local discoloration, as well as traces of process lubrication are allowed. Sale of products with unedged edges is allowed;
