Low Temp Aluminum Brazing Rods from China Factory - High-Quality Suppliers for Aluminum Projects
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
-
1
Welding of copper and aluminum wires in radiators, motors, batteries, and household appliances.
-
2
Welding of aluminum and copper tubes in condensers/evaporators in refrigerators and air conditioners.
-
3
Welding of aluminum wires and copper joints, copper bars, and aluminum foil in transformers and reactors.
-
4
Recasting and welding of aluminum parts for the second time when they are missing or worn over a large area.

Frequently Asked Questions
What materials can these low-temperature brazing rods weld?
They are suitable for welding aluminum, aluminum alloys, die casting, bronze, nickel, titanium, zinc, copper, brass, and most other non-ferrous (non-magnetic) metals.
Is flux required during the welding process?
No, these rods do not require any flux, allowing for quick, clean, and easy welding.
What is the operating temperature of these rods?
The operating temperature is approximately 387℃, with a melting point of around 420℃, which is significantly lower than typical brazing alloys.
How strong is the bond created by these brazing rods?
They offer exceptional strength, featuring a tensile strength of 39,000 psi and a compressive strength of 60,000 to 75,000 psi, which often yields a bond stronger than the parent material.
What heat sources can be used with these rods?
You can weld quickly and easily using any standard handheld welding torch, including Oxyacetylene, Mapp, Map/Pro, or propane systems.
Are custom sizes available for these brazing rods?
Yes, while our standard diameters range from 0.8mm to 2.0mm, other custom sizes can be manufactured according to specific client requirements.
