The difference between purple copper and brass
| Characteristics | Purple Copper | Brass |
| Composition | Pure copper (Cu ≥ 99.9%) | copper zinc alloy (Zn 5% -45%) |
| Strength | Low(200-250 MPa) | High(300-500 MPa) |
| Hardness | Low (40-100 HB) | High(60-200 HB) |
| Ductility | Excellent | Good |
| Conductivity | Excellent(close to 100% IACS) | Low(20% -60% IACS) |
| Thermal conductivity | Excellent(401 W/(m · K)) | Low (120 W/(m · K)) |
| Corrosion resistance | Good(easy to form copper green) | Good(easy to remove zinc corrosion) |
| Machinability | easy to stick tool | especially lead containing brass |
| Appearance | Purple red | golden yellow |
Detailed Field Applications
1.Electronic enterprises
The high conductivity and thermal conductivity of copper make it an ideal material for the electronic and electrical industry
Useage:Electronic appliances: wires, connectors, heat sinks
Reason: The conductivity of copper is close to 100% (IACS standard), making it suitable for efficient power transmission.And has excellent thermal conductivity, suitable for radiator applications.
2. Power industry
Copper is used in the power industry to manufacture parts for efficient transmission and distribution of electrical energy.
Useage: busbar, switch contacts, transformer windings.
Reason:The low resistance characteristic of copper reduces electrical energy loss. Corrosion resistance ensures long-term stable operation.
Useage:RF connectors, waveguide components, antenna components.
Reason:The high conductivity and low signal loss characteristics of copper are suitable for high-frequency signal transmission.
4. Industrial Machinery Industry
Copper is used in industrial machinery to manufacture parts that are corrosion-resistant and have high thermal conductivity.
Useage:heat exchanger parts, seals, bearing bushings.
Reason:The corrosion resistance of copper is suitable for harsh environments.
Excellent thermal conductivity, suitable for heat exchanger applications.
Useage:surgical instruments, medical equipment parts.
Reason:The corrosion resistance and ease of processing of purple copper are suitable for medical environments.High conductivity is suitable for electrical components in medical equipment.
