C19005 is a high-performance copper alloy material with optimized chemical composition and physical properties, possessing excellent comprehensive performance. This material exhibits stability in terms of conductivity and thermal conductivity, and can meet the basic physical performance requirements of many industrial application scenarios. Combining high strength, high conductivity, and high temperature resistance, with a tensile strength close to steel and a conductivity of 45% -60% IACS, it is an ideal choice for high-end electronic and automotive components.
Chemical Composition
C19005 is a low-nickel copper alloy. The typical chemical composition is as follows:
| Element | Weight % |
|---|---|
| Copper (Cu) | Balance |
| Nickel (Ni) | 1.0 - 1.8% |
| Silicon (Si) | 0.25 - 0.80% |
| Phosphorus (P) | 0.02 - 0.15% |
| Other Elements | ≤ 0.1% total |
The alloy is strengthened through the formation of Ni-Si intermetallic compounds during heat treatment (solution treatment and aging)
Mechanical Properties (Typical for TM04 - Mill-Hardened Temper)
| Property | Typical Value |
|---|---|
| Tensile Strength | 520 - 620 MPa |
| Yield Strength (0.2% offset) | 450 - 550 MPa |
| Elongation at Break | 5% - 15% |
| Hardness (Vickers) | 150 - 190 HV |
Thermal Stress Relaxation
P=Larson Miller parameter T=temperature(℃) t=time(h)
Example:
Application conditions: Maintain for 1000 hours at 150°C.
Formula substitution: T = 150, t = 1000
P=(150+273)×(20+lg (1000))×0.001=9.729
Graph reference: When P = 9.729, the stress retention rate is approximately 85%.
Conclusion: Under the conditions of 150°C / 1000h, the remaining stress of this material is close to 85%.
Key Properties
C19005 is a high-strength and high conductivity copper alloy that can be strengthened by heat treatment. It achieves an excellent balance between strength, conductivity, and heat resistance. Its main characteristics can be summarized as follows:
- High strength: By adding nickel and silicon to form intermetallic compounds, the strength and hardness of the alloy can be significantly improved after heat treatment (solid solution+aging). Its tensile strength is much higher than that of pure copper and ordinary brass, and can even approach the level of some steel.
- High conductivity: Despite containing alloying elements, its conductivity remains at a high level (usually between 45% -60% IACS, depending on the heat treatment state), much higher than stainless steel and most copper alloys (such as bronze and white copper), making it particularly suitable for situations that require simultaneous conduction of high currents and mechanical stress.
- Excellent heat resistance: It has good anti softening ability and can maintain its strength and hardness at high temperatures (such as below 400 ° C), making it suitable for components working in high-temperature environments.
- Good corrosion resistance: Inheriting the excellent resistance to atmospheric and seawater corrosion of copper alloys, it also has certain resistance to stress corrosion cracking.
- Good processing and plating performance: It can be further strengthened through cold processing and is easy to electroplate (such as tin plating, silver plating, nickel plating, etc.), which is very important for surface treatment of electronic connectors.
- Non magnetic: Like most copper alloys, it is a non-magnetic material.
