Mechanical Properties

The dimensions of C36000 copper rods vary depending on the shape and processing technology:


Round rods

Diameter range: Common 1.5-100mm, some suppliers provide precision specifications from 0.0625 inches (about 1.5875mm) to 4.5 inches (about 114.3mm)

Length range: Generally 2500-6000mm, some standard lengths are 12 feet (about 3.66 meters)


Flat rods/rectangular rods

Typical dimensions are 15.88mm×3.18mm, other specifications can be customized.

Tolerance requirements: Diameter tolerance ranges from ±0.0013 inches to ±0.008 inches

Specific implementation depends on the standard.


International Standards

C36000 mainly follows the following standards:

ASTM B16: Standardizes chemical composition, mechanical properties and dimensional tolerances, requiring copper content of 60.0-63.0% and lead of 2.5-3.7%.

AMS 4610 and SAE J461: Supplementary material manufacturing and delivery requirements.

Other corresponding grades: such as JIS C3604, DIN CuZn39Pb3, etc., suitable for different countries/regions.


Main components:


Copper (Cu): 60.0%-63.0%

Zinc (Zn): As a balance, the content is about 32.5%-37.5%

Lead (Pb): 2.5%-3.7%, used to improve cutting performance

Iron (Fe): ≤0.35%

Other impurities (such as aluminum, phosphorus, sulfur, etc.): total ≤0.5%

Other trace components:


Aluminum (Al) ≤0.5%, used to strengthen the alloy

Sulfur (S), phosphorus (P), etc. ≤0.01%
