Project Description

Seamless aluminum tubing alloy 6063


  • Seamless aluminum tubing is made of aluminum alloy grade 3003 or 6063, its out layer is 10% thickness solder layer with alloy 4045 or 4343.
  • soler layer can add 0.5 to 1.5% chemical Zn which can strengthen sacrificial anode protection function.
  • Characteristic: soler layer is well-distributed and higher burst pressure resistance and heat exchanger welding quality are stable.

Material Construction

  • Based material: 3003 or 6063 alloy grade seamless aluminum tubing
  • Outside Diameter: OD16 to 30, size tolerance:+/-0.05mm
  • Solder layer: 4343 or 4045 alloy soldering material
  • Mechanical properties: tensile strength 130 to 150MPA, and Elongation more than 15%, Temper: H14
  • Wall thickness: 1.0 to 1.6mm, tolerance: +/-0.08mm

Condenser-Tubeseamless aluminum tubes

Seamless aluminum tubing application

  • Seamless aluminum tube with 4045 and 4343 soldering layer used for parallel flow heat exchanger
  • Parallel flow heat exchanger is used for the automobile air conditioner industry.
  • The fixed-size collector tube is well-distributed material, make heat exchanger welding technical stable.
