Production process and product advantages of C53400 copper rod:

1. Production process

Raw material processing and smelting

The production of C53400 copper rod usually uses waste brass, waste copper and zinc ingots as raw materials, and is smelted in an industrial frequency furnace, which produces smoke and slag in the process. After wet screening of the slag, large particles are recycled, wastewater is precipitated and treated, and dust is separated and disposed.

Continuous casting and extrusion

The smelted copper liquid enters the continuous casting link and forms a copper rod billet after cooling. Subsequently, a hot extrusion process (such as a 38MN reverse extruder) is used to improve the material density and surface finish through high-pressure extrusion. Evidence shows that the extrusion method can effectively cover the production of multiple grades, and the products have high density, high strength, and significantly improved yield.

Subsequent processing

Continuously cast rods and extruded rods need to be annealed to optimize performance. Some processes also include skinning to remove the oxide layer, cutting and stretching processes, and scraps are recycled. Red punching (heated to 800℃ by natural gas) is used to form semi-finished products such as valves and joints.

2. Product Advantages

Excellent mechanical properties

C53400 is a leaded phosphor bronze (ASTM B103M/B139M standard). The ratio of tin (3.50~5.80%), lead (0.80~1.20%) and phosphorus (0.03~0.35%) gives the material high wear resistance, fatigue resistance and pressure resistance, and is suitable for precision parts such as bearings, gears, and shafts.

Good processing performance

The material has excellent cutting performance and acceptable cold processing performance, which is convenient for the manufacture of complex parts. The addition of lead elements further improves cutting efficiency and reduces tool wear.

Corrosion resistance and environmental adaptability

The corrosion resistance of phosphor bronze makes it outstanding in harsh environments such as marine engineering and chemical industry, and can withstand oxidation and chemical erosion for a long time.

Efficient production process and quality control

Domestic mainstream enterprises adopt continuous and automated production lines, combined with computer control and non-destructive testing technology to ensure that the intrinsic quality and surface accuracy of the products reach the international advanced level. Innovative technologies such as reverse extrusion reduce production costs and increase the yield rate.

Wide range of applications

C53400 copper rod is suitable for many industries such as machinery manufacturing, power, shipbuilding, electronics, etc., especially in high-strength and wear-resistant scenes (such as bushings and thrust rings). Its conductivity also supports some electrical engineering needs.
