Cu and Al tube

Manufacturer

FineTech Electronic S&T Co., Ltd.

The copper aluminum multiple-unit tube is the copper aluminum contact surface for the metallurgy union.Is one kind of new tubing, its flank for guards against rust the aluminum alloy, the inside is the oxygen-free copper, between the copper aluminum for the interatomic metallic bond close binder.
Tube proportion 3.3G/CM3, is approximately the copper pipe 1/2.7, uses the copper aluminum multiple-unit tube substitution copper pipe, may save the copper material above 75%.The tube internal surface copper level has the good inoxidizability.The outer layer rust prevention aluminum alloy may bear the atmospheric corrosion.The copper aluminum multiple-unit tube unifies copper good instantaneous heat absorption capacity and aluminum good radiation ability, enable this kind of tubing to have the fine heat-transfer property.Uses in each kind of radiator suitably.

 

 The tube load ratio is: Copper/aluminum 30/70, volume ratio: Copper/aluminum 10/90.
 Tensile strength: ≥125Mpa   
  Elongation ratio: ≥35%   
  Flaring rate: ≥40%
