Production process and product advantages of C63200 copper rod:

1. Production process

Raw materials and smelting

The production of C63200 copper rod uses electrolytic copper, zinc ingots, copper bran and other raw materials as the main raw materials. After being mixed in proportion, they are put into the melting furnace and heated to liquid state (about 1100℃), and continuous smelting is carried out in a medium-frequency electric furnace. This process achieves efficient melting by cutting metal materials with magnetic induction lines, and adds slag removers to remove impurities.

Forming and processing

After the molten metal liquid is formed by the traction machine, it needs to go through processes such as polishing, straightening, and cutting. Domestic advanced enterprises adopt the "large-tonnage electric furnace smelting-submerged liquid transfer-multi-head multi-stream horizontal continuous casting" technology. A single furnace can simultaneously cast 64 products of different specifications, and the production efficiency is more than 10 times higher than that of traditional processes, and smoke emissions are reduced (dust concentration <10mg/l). In addition, precision copper rods are often produced by extrusion, combined with continuous casting and stretching processes, which significantly improves the density and surface smoothness of the material.

Quality Control

The production process is equipped with a bag dust removal system, and computer management and non-destructive testing technology are used to ensure stable product quality.

2. Product Advantages

Excellent mechanical properties

C63200 aluminum bronze has high strength, tensile strength of 862 MPa, yield strength of 483 MPa, high hardness and excellent wear resistance, suitable for heavy-duty mechanical parts (such as gears, bearings, pistons, etc.). Its fine grain structure and heat treatment process (quenching + tempering) further enhance performance consistency.

Excellent corrosion resistance

It performs well in seawater, fresh water and acid/alkali environments, especially suitable for marine engineering and shipbuilding. Its κ phase structure is optimized by forging and heat treatment to avoid selective corrosion problems.

Versatility and processing adaptability

The product has various forms (rods, plates, tubes, flanges, etc.), supports customized sizes and delivery states (forging, annealing, etc.), and meets the needs of different industries. It has good welding performance, can be connected by MIG/TIG technology, and has excellent cold/hot processing performance.

Low magnetic permeability and safety

The low magnetic permeability makes it suitable for instrument systems and explosion-proof environments (such as petrochemicals and mining), and it is not easy to generate sparks in explosive environments.

Industry certification and standards

It complies with international standards such as ASTM B150, ASME, AWS, and is widely used in high-demand fields such as nuclear submarines and aerospace.
