I. Introduction and application of lead-free copper rods
With the increasing awareness of environmental protection, lead-free copper rods have gradually become a new type of environmentally friendly material in the copper processing industry. Compared with traditional leaded copper materials, lead-free copper has more excellent performance and a wider range of applications, attracting more and more manufacturers to choose to use.
Common grades and properties of lead-free copper rods
1. C11000
C11000 is a common grade of lead-free copper rods, with good electrical conductivity, workability and plasticity, widely used in electrical and heat exchanger industries. Its hardness and strength are low, and it can be used to make high-precision parts.
2. C14200
C14200 is a high-strength, high-hardness lead-free copper bar that is often used to make high-precision machine parts and bearings, etc. It has excellent resistance to wear and tear, and can be machined and molded. It has excellent wear resistance and electrical conductivity.
3. C14420
C14420 is a self-lubricating lead-free copper rod containing small amounts of tin and nickel and other metal elements, with excellent wear resistance and self-lubricating properties, widely used in automotive and mechanical fields.
Third, the comparison of different grades
Different grades of lead-free copper rods have different advantages and disadvantages. C11000, C14200, C14420 three grades, for example, C11000 has good electrical conductivity and machinability, but the hardness and strength of the lower; C14200 has a high strength and high hardness, can be manufactured high-precision machine parts and bearings, etc.; C14420 has excellent abrasion resistance and self-lubricating properties, suitable for the vehicle and machinery industry. Users should choose according to the specific performance needed.
Fourth, the summary
Lead-free copper rod is a new type of environmentally friendly material with better performance and a wide range of applications. Different grades have different advantages and disadvantages, the user should choose according to the specific performance needed to choose.
