Copper strip size:
Thickness range:
General copper strip: 0.01-2.0mm (commonly seen in brass strip, red copper strip, etc.).
Electrical copper strip (such as BS EN 13599 standard): 0.05-25mm, width 10-1250mm.
Chinese standard (GB/T 2059): thickness 0.5-0.8mm (tolerance ±0.012mm), width can be customized on demand (tolerance ±0.1mm).
Width range:
General copper strip: 4-600mm, industrial copper strip can be expanded to 8-1250mm (such as copper strip for transformer)
International Standards and Specifications
ASTM Standards:
ASTM B36: Applicable to soft annealed (O60 state) copper strip and plate of C23000 for general industrial use.
ASTM B152: Covers technical parameters such as tensile strength (≥195MPa) and elongation (≥30%) of copper strip.
European Standards (EN):
BS EN 13599:2014: Specifies the composition, electrical conductivity (≥100% IACS), thickness (0.05-25mm) and width (10-1250mm) of copper plates for electrical use, and includes tolerance requirements.
Chinese Standards (GB/T):
GB/T 2059: Requirements for thickness tolerance (±0.012mm), mechanical properties (such as tensile strength ≥195MPa) and surface quality of copper strip.
GB/T 17793—2010: Specifies the allowable deviation of the dimensions of copper strip, including width, length, straightness, etc.
Other standards:
DIN 17660: German brass alloy standard, covering the chemical composition and properties of CuZn15 (corresponding to C23000).
ISO 426-2: International general standard for copper-zinc alloys.
Main components:
Copper (Cu): The content ranges from 84.0% to 86.0%.
Zinc (Zn): As a residual component, it usually accounts for about 14%-16%.
Trace elements:
Lead (Pb): The maximum content does not exceed 0.05%.
Iron (Fe): The maximum content does not exceed 0.05% (some standards such as GB/T 5231-2012 stipulate that Fe≤0.03%)
Mechanical properties vary depending on processing status, hardness level and product size:
Tensile strength:
H01 (semi-hard): Minimum tensile strength for bars with diameters less than 1/2 inch is 305 MPa (44 ksi), and for bars with diameters greater than 1 inch is 275 MPa (40 ksi).
H02 (semi-hard): 345 MPa (50 ksi) for bars with diameters less than 1/2 inch, and 275 MPa (40 ksi) for bars with diameters greater than 1 inch.
H04 (hard): 435 MPa (63 ksi) for bars with diameters less than 1/2 inch, and 400 MPa (58 ksi) for bars with diameters greater than 1 inch.
Combined with other standards, the tensile strength range can reach 269-724 MPa (39-105 ksi).
Yield Strength:
Wide range, from 69 MPa (10 ksi) to 480 MPa (70 ksi), depending on processing
Elongation:
Up to 55% (2-inch gauge length), elongation for different hardness grades in ASTM standards varies with diameter.
Hardness:
Rockwell B hardness ranges from 48-87, Rockwell Superficial 30T hardness ranges from 51-77; hardness values vary in different annealing states.
Other Parameters:
Modulus of Elasticity: Approximately 110-117 GPa.
Poisson's Ratio: 0.33-0.34.
Shear Strength: 220-340 MPa.
