China Low Temp Aluminum Brazing Rods For Aluminum Projects Factories, Factory

Taojun series aluminum brazing alloys are advanced filling materials designed for aluminum and aluminum alloy components. By optimizing the ratio of elements such as silicon (Si) and magnesium (Mg), they achieve a perfect balance of low melting point, high strength and excellent corrosion resistance. They are suitable for automobiles, refrigeration equipment and other fields, providing permanent connections with high air tightness and excellent thermal conductivity.

Product Description

Material

Usually aluminum (Al) is used as the matrix, and alloy elements such as silicon (Si), copper (Cu), zinc (Zn), and magnesium (Mg) are added to reduce the melting point and improve performance.

Advantages

1 Low operating temperature

Much lower than most similar products (387℃), which can repair and manufacture a wider range of aluminum and other non-ferrous metal parts.

2 Low melting point

Around 420℃, the typical brazing alloy melting point is 500-640℃, good fluidity, strong hardness and toughness.

3 Super strong bonding strength

39,000 psi tensile strength and 60,000 - 75,000 psi compressive strength provide your repair or manufacturing every time stronger than the parent material.

4 No Flux Required

Suitable for aluminum, aluminum alloys, die casting, bronze, nickel, titanium, zinc, copper, brass and most non-ferrous metals (non-magnetic), weld quickly and easily with any handheld welding gun (Oxyacetylene, Mapp, Map/Pro or propane).

Appliance

  • Welding of copper and aluminum wires in radiators, motors, batteries, and household appliances.
  • Welding of aluminum and copper tubes in condensers/evaporators in refrigerators and air conditioners.
  • Welding of aluminum wires and copper joints, copper bars, and aluminum foil in transformers and reactors.
  • Recasting and welding of aluminum parts for the second time when they are missing or worn over a large area.

Frequently Asked Questions

What is the melting point of these low temperature aluminum brazing rods?
The melting point is approximately 420°C. This is significantly lower than typical brazing alloys, which require temperatures between 500°C and 640°C.
Do these brazing rods require any flux?
No, these rods do not require any flux. They are designed for quick and easy welding without the need for additional fluxing agents.
What metals can be repaired using these rods?
They are highly suitable for aluminum, aluminum alloys, die casting, bronze, nickel, titanium, zinc, copper, brass, and most other non-ferrous (non-magnetic) metals.
Which type of welding gun can I use?
You can easily weld using any handheld welding gun, such as Oxyacetylene, Mapp, Map/Pro, or propane torches.
How strong is the bond after welding?
These rods deliver exceptional bonding strength, providing 39,000 psi of tensile strength and 60,000 to 75,000 psi of compressive strength, which is often stronger than the parent material.
Can they be used to weld different metals together, like copper and aluminum?
Yes, they are excellent for joining dissimilar non-ferrous metals, including welding copper and aluminum wires in motors and radiators, or copper/aluminum tubes in air conditioners.
