C69833 Data Sheet
Chemical Composition of C69833 Coper:
Here is the chemical composition of C69833 lead-free brass alloy presented in a horizontal table format:
| Element | Copper (Cu) | Zinc (Zn) | Silicon (Si) | Nickel (Ni) | Iron (Fe) | Lead (Pb) | Manganese (Mn) |
|---|---|---|---|---|---|---|---|
| Content | 74.0 – 77.0% | Balance | 2.0 – 3.5% | 0.3 – 1.3% | ≤ 0.10% | ≤ 0.09% | ≤ 1.0% |
Notes:
- Copper (Cu): Primary component providing base mechanical properties and electrical conductivity.
- Zinc (Zn): Balances the alloy, contributing to strength and corrosion resistance.
- Silicon (Si): Enhances mechanical properties and corrosion resistance.
- Nickel (Ni): Adds strength and hardness, improving corrosion resistance.
- Iron (Fe): Trace element, kept low to prevent embrittlement.
- Lead (Pb): Lead-free characteristic makes it suitable for environmental and potable water systems.
- Manganese (Mn): Increases strength and hardness.
Mechanical Properties of C69833
| Property | Value |
|---|---|
| Tensile Strength | 400 – 650 MPa |
| Yield Strength | 150 – 500 MPa |
| Elongation | 10 – 35% |
| Hardness | 80 – 100 HRB |
| Modulus of Elasticity | Approximately 110 GPa |
| Shear Strength | Approximately 230 MPa |
Notes:
- Tensile Strength: The maximum stress that the material can withstand while being stretched or pulled before breaking.
- Yield Strength: The stress at which a material begins to deform plastically.
- Elongation: The percentage increase in length before rupture, indicating the ductility of the material.
- Hardness: Measured on the Rockwell B scale (HRB), indicating the material’s resistance to indentation.
- Modulus of Elasticity: The ratio of stress to strain in the elastic deformation region, indicating the stiffness of the material.
- Shear Strength: The maximum stress that the material can withstand in shear before failing.
These properties make C69833 suitable for applications requiring a combination of strength, ductility, and corrosion resistance, such as in potable water systems, building hardware, and automotive components.
