Environmental automatic seamless copper-aluminum brazing filler metal solder saving cost JH***2TL
 

Features:
a. Saving materials: The copper-aluminum solder with gap, being opened easily in bend process, causing flux leakage and brazing solder wasting. While JH***2TL seamless copper-aluminum solder, as without seam, and avoid this negative phenomenon thoroughly.
b. Improving welding quality: It is easy of packed flux absorbing humidity and cause unstable welding quality and weld porosity for the gap existing in the copper-aluminum solder with seam; hence, oversea company take seamless technology; JH***2TL solder, with stable quality and lower rate of weld porosity for seamless, and not easy to absorb humidity.
c. Choosing JH***2TL solder, the leaking rate of weld porosity  is lower than 0.*1%, while the one with gap is too far to reach this requirement.
Applications:
1.Aluminum wire and copper joint in transformers Reactors, Copper bars and aluminum foil welding;
2.Tube of aluminum and copper welding for condenser and evaporator of refrigerator and air conditioner;
3.Aluminum and copper welding  for radiator, television, battery, and house appliance,
4.Joint of airplane air-filter and rocket pilot valve,
5.Other brazing joint of copper and aluminum parts, etc.
