Production process and product advantages of 17510 copper strip:

1. Production process

Smelting and continuous casting process

Multi-cavity induction furnace smelting is adopted, and the copper strip blank is directly produced in combination with the coupled crystallizer horizontal continuous casting technology. This technology eliminates the traditional hot rolling and milling process, shortens the process flow and reduces energy consumption.

Some enterprises adopt the upper furnace process to produce ingots, with specifications ranging from 15~18×300~450×Lmm and a maximum single weight of 6.5 tons.

Forming process

Continuous extrusion method: Φ20 copper rod is heated and deformed by continuous extrusion, and the blank with the required cross-sectional shape is generated after circulating water cooling.

Rolling process: including milling, rough rolling, intermediate annealing, finishing rolling, finished product annealing and other steps, and finally forms a high-precision copper strip. The surface treatment adopts acid purification and passivation process to improve oxidation resistance and surface quality.

Energy-saving and environmentally friendly technology

Use hot water degreasing instead of acid and alkali washing to reduce pollution; short-process wide-width production process (such as 650mm and above wide-width copper strip) further reduces energy consumption.

2. Product advantages

Excellent physical properties

High strength and high hardness: The tensile strength is as high as 900-1400 MPa (about 130-140 ksi), and the hardness can reach HRB 100, which is equivalent to tool steel, suitable for high-stress parts such as spring leaves and mold inserts.

High electrical conductivity/thermal conductivity: The electrical conductivity can reach 45-60% of copper (some data mention more than 90% IACS), and the thermal conductivity is 140 BTU/ft·hr·°F, which meets the needs of efficient electric heat transmission.

Environmental resistance

Corrosion resistance: It has excellent corrosion resistance to seawater, atmosphere and chemicals, and is suitable for ships, chemical industry and other fields.

High temperature stability: It still maintains mechanical properties at high temperatures (such as aging at 500℃), and the precipitation phase structure is stable, which is suitable for high temperature applications.

Processing and functional advantages

Easy to process: supports stamping, welding (brazing, gas shielded welding, etc.), heat treatment and other processes, and can be processed into parts with complex shapes.

Non-magnetic and anti-fatigue: non-magnetic and anti-fatigue properties are significant, suitable for precision electronic equipment and aerospace components.

Wide application areas

Covering high-tech fields such as electronics (connectors, relays), new energy (power battery copper strips), molds (punches, die-cast plungers), and aerospace (heat transfer plates).
