Key features:
Wear resistance and friction reduction: Due to the presence of tin and phosphorus, the friction coefficient is low (0.0125 when lubricated), suitable for wear-resistant parts such as bearings and sleeves.
Corrosion resistance: Excellent performance in the atmosphere, fresh water and sea water.
Cold processing performance: It can be strengthened by cold pressure processing, but it is easy to become hot brittle during hot processing.
Electrical conductivity/thermal conductivity: The thermal conductivity is about 54.4 W/(m·K), and the electrical conductivity is moderate.
Welding performance: Supports soldering, copper welding, and arc welding, but submerged arc welding and electroslag welding have poor results.
C52100 copper plate is a high-performance phosphor bronze, and its production process and product advantages are as follows:
1. Production process
Processing technology
Cold rolling and heat treatment: C52100 copper plate is usually processed by cold rolling and annealing process to ensure the uniformity and mechanical properties of the material.
Hot pressing forming: During the production process, hot pressing forming technology is used to give the material higher density and strength.
Surface treatment: Some products may be plated, such as tin plating or environmentally friendly tin plating, to improve corrosion resistance and conductivity.
Equipment and technology
Advanced furnace coil mills and horizontal continuous casting machines are used in the production process, which can effectively control the thickness tolerance and mechanical properties of the plate.
Environmental protection and quality control
The production process complies with international standards (such as EN 1652/1654), and the impurity content is strictly controlled to ensure the high quality and environmental protection of the product.
2. Product Advantages
High Strength and High Toughness
C52100 copper plate has high tensile strength (379-965 MPa) and elongation (165-552 MPa), as well as good toughness, and is suitable for industrial applications that require high strength and high wear resistance.
Corrosion resistance
The material exhibits excellent corrosion resistance in atmospheric, freshwater and seawater environments, and maintains stable performance even under high temperature conditions.
Excellent Processing Performance
C52100 copper plate is easy to cut, form and weld, but not easy to braze. This gives it a significant advantage in the manufacture of complex parts such as sliding bearings, gears, and transmission components.
Good Conductivity
As a type of copper alloy, C52100 copper plate has excellent conductivity and is suitable for applications such as electrical equipment and connectors.
Wide Range of Application
Industrial Field: Widely used in aerospace, power and petroleum, machinery manufacturing and other fields.
Electronic Industry: Used to manufacture precision connectors, transformers, radiators, etc.
Environmental Protection: RoHS compliant and suitable for the use of lead-free solder.
Economy and Practicality
Compared with other copper alloys (such as beryllium bronze and copper), C52100 copper plate strikes a balance between strength and economy, and is suitable for medium and low-end applications.
