The production process and product advantages of C36000 copper wire can be summarized as follows:
1. Production process
The production process of C36000 copper alloy mainly includes the following steps:
Making and smelting: According to the alloy composition requirements (copper 60.0-63.0%, lead 2.5-3.7%, zinc balance, etc.), accurately weigh the raw materials and melt them into liquid to ensure uniform mixing of elements.
Casting: The molten copper liquid is poured into castings, and common forms include bars, plates, pipes, etc.
Heat treatment: Adjust the organizational properties through annealing (425-700°C) or aging hardening to improve hardness, strength or ductility.
Machining:
Hot processing: Suitable for forging, extrusion, etc., with a temperature range of 625-800°C.
Cold processing: Formed by rolling, wire drawing, cutting and other processes, and secondary annealing may be required after processing to eliminate stress.
Surface treatment: Such as polishing, plating, etc., to enhance corrosion resistance or aesthetics.
For copper wire production, it may involve processes such as wire drawing, bundle twisting, and insulation extrusion (such as the insulation copper wire process of ), but the core process of C36000 is still mainly alloy preparation and forming.
2. Product advantages
Due to its unique composition and process, C36000 copper alloy has the following advantages:
Excellent cutting performance:
The cutting index reaches 100% (industry benchmark), the chip breaking is smooth, suitable for high-speed drilling, milling and other precision processing, and the tool wear is low.
Known as the "benchmark for easy-to-cut brass", it has a high surface finish and is suitable for precision parts such as watch parts and gears.
Excellent mechanical properties:
Tensile strength: 330-350 MPa in annealed state, and up to 550 MPa in hard state.
Hardness: Brinell hardness 80-150 HB, which can be further improved through work hardening.
Ductility: The elongation can reach more than 30%, suitable for hot and cold forming.
Good corrosion resistance:
It has strong corrosion resistance to seawater, atmosphere, and freshwater environments, and is suitable for ships, plumbing accessories, etc.
Electrical and thermal conductivity:
Although the conductivity is lower than pure copper, it is still better than most alloys, and is suitable for electrical connectors, heat dissipation components, etc.
Multifunctional processing adaptability:
Supports a variety of processes such as casting, forging, extrusion, welding (soft soldering/brazing is excellent, arc welding is not recommended).
Wide application areas:
Automobile: sensor housing, fluid connector, brake parts.
Electronics and electrical: connectors, switches, precision resistors.
Hardware and machinery: locks, valves, gears, pump bodies.
