Production process and product advantages of C26800 copper tube:

1. Production process

The production process of C26800 copper tube mainly includes the following key steps:

Smelting: Use an industrial frequency furnace to melt cathode copper and phosphor copper alloy at a high temperature of 1200℃.

Continuous casting: The copper tube billet is formed by a horizontal continuous casting process and water-cooled to 50℃.

Rolling processing: Planetary rolling, triple drawing, coil drawing and other processes are used to refine the tube structure, and scraps and waste emulsion are generated during the process (need to be recycled).

Annealing treatment: The online annealing temperature is controlled at 540-600℃ to eliminate internal stress and improve plasticity.

Forming and surface treatment: including bending, welding, surface cleaning (using cleaning agent), rewinding flaw detection, etc., and finally the finished copper tube is obtained.

Note: Exhaust gas (such as G2-G4), waste mineral oil (S5) and noise pollution need to be controlled during the production process.

2. Product advantages

Excellent mechanical properties

Tensile strength ≥440 MPa, elongation ≥25%, with both high strength and toughness.

Excellent cold processing ability, suitable for complex forming processes such as stamping and deep drawing, but relatively weak machining performance (rating 30/100).

Outstanding corrosion resistance

Good resistance to atmospheric, fresh water and dezincification corrosion, suitable for corrosive environments such as ships and heat exchangers.

Wide processing adaptability

Supports hot processing (775-850℃) and cold processing, can be forged, extruded, rolled, and has excellent welding and brazing performance.

It can be processed into various forms such as pipes, plates, wires, etc. to meet complex industrial needs.

Electrical and thermal conductivity

Good electrical conductivity, resistivity of 38.4 micro-ohm-cm, suitable for electronic components and radiator manufacturing.

Wide application areas

Mainly used in radiator cores, air conditioning connecting pipes, valves, condensers, etc., and covering industries such as automobiles, construction, and electricity.
