Large diameter forged aluminum tube technology

Chalco uses 10, 000-ton ultra-large free forging equipment to manufacture large diameter aluminum tubes, commonly using medium to high-strength alloys such as 6061, 6082, and 7075, offering excellent strength and toughness.

This process does not require molds, providing greater customization flexibility to meet various requirements for tube dimensions, wall thickness, and length.

Large diameter aluminum tube vertical extrusion technology

Chalco's patented vertical extrusion technology breaks through the limitations of traditional processes, enabling the production of large diameter seamless aluminum tubes while overcoming the length constraints of forging processes.

Using a 500MN extrusion machine for billet perforation and vertical pressing, the entire extrusion process takes only 10 minutes, significantly reducing production time.

The advanced shaft furnace heat treatment system ensures a temperature deviation of less than ±5°C during heating, with the holding process deviation within ±5°C.

Dimensional accuracy: Precise measurement of inner diameter, outer diameter, wall thickness, and length using calipers, micrometers, and other precision instruments, ensuring dimensions are within specified tolerances.
Straightness and roundness: Checks the tube's straightness and roundness to ensure uniform wall thickness and compliance with design requirements.
Ultrasonic testing: Detects internal defects like cracks and voids using ultrasonic testing.
Metallographic examination: Observes grain size and distribution under a metallographic microscope to ensure uniform material structure.
Mechanical property testing: Measures tensile strength, yield strength, and elongation using a tensile testing machine.
Hardness testing: Measures material hardness using a hardness tester to ensure it meets the required standards.
Pressure testing: Applies internal pressure to the tube to test its pressure resistance.
