Production process and product advantages of C63200 copper plate:

1. Production process

Excellent hot processing performance

C63200 aluminum bronze has good plasticity at high temperature and can be formed by hot extrusion, hot rolling and hot forging, which is suitable for the manufacture of complex structures. Its ingot structure is α phase + eutectoid, with good fluidity, which is convenient for casting and extrusion.

Cold processing adaptability

This material has a certain cold processing ability and can be cold rolled, bent and formed, which is suitable for the manufacture of precision parts.

Welding and cutting process

Welding: Suitable for argon arc welding, flash welding and copper welding, but not suitable for gas welding, tin welding and electroslag welding.

Cutting performance: The cutting performance is 30%, and the grinding performance is medium. It is necessary to combine appropriate process parameters to optimize efficiency.

Heat treatment strengthening

The grain structure can be refined (average grain size 31.8μm) through quenching (such as 845°C water quenching) and tempering (such as 715°C tempering for 3 hours), which significantly improves the mechanical properties and corrosion resistance.

2. Product Advantages

Excellent mechanical properties

High strength and wear resistance: tensile strength 640-710 MPa, yield strength 310-350 MPa, Rockwell hardness 88 HRB, suitable for high-load parts such as gears, bearings, valves, etc.

Excellent toughness: elongation of 15%-25%, good impact resistance, can absorb energy without brittle fracture.

Excellent corrosion resistance

Stable in seawater, fresh water and non-oxidizing acids (such as hydrochloric acid and sulfuric acid), widely used in marine engineering (such as seawater pumps, submarine pipelines) and petrochemical equipment

Improving the κ phase structure through forging process to avoid selective corrosion problems and improve long-term stability.

Special functional characteristics

Spark-free characteristics: no sparks are generated under impact, suitable for explosion-proof tools and flammable environments.

Thermal conductivity and electrical conductivity: thermal conductivity 35-58.6 W/m·K, electrical conductivity 7.0% IACS, suitable for molds and heat dissipation components.

Economical and Substitutable

Compared with tin bronze, stainless steel and other materials, it has lower cost and can replace expensive alloys to reduce manufacturing costs.

Wide Application Fields

Covering multiple industries such as aviation (brackets, flanges), ships (propellers, drive shafts), military industry (nuclear submarine parts), automobiles and oil extraction
