Introduction of 4004 aluminum alloy brazing plate

4000 series aluminum plates belong to the series with higher silicon content. Usually, the silicon content is between 4.5-6.0%. It belongs to building materials, mechanical parts, forging materials, welding materials; low melting point, good corrosion resistance.

4004 is a brazed aluminum-based solder and aluminum alloy brazing plate. During brazing, the material to be brazed is not easily melted. The brazing melts and fills the joint to connect the workpieces. The aluminum-based brazing material can be wrapped on the aluminum alloy core material to make an aluminum alloy brazing plate, which is widely used in Manufacture of heat exchangers.

Advantages of 4004 aluminum alloy brazing plate

1. 4004/4343/4045 and other composite materials to meet different application scenarios and different needs.
2. The width of 4004 aluminum alloy brazing plate can be 2650mm, and the thickness can be 600mm.

Chemical component of 4004 aluminum alloy brazing plate

Use of 4004 aluminum alloy brazing plate

4004 aluminum alloy brazing plate is usually used as part of a brazed assembly, and the other part is an uncoated brazable aluminum alloy material. When brazing, the entire assembly is placed in a furnace or a salt bath and heated evenly to a high temperature, The brazing material on the brazing plate melts, flows by capillary action and gravity, fills the joints of the parts to be connected, and can weld hundreds or more joints at the same time. Widely used in the manufacture of various heat exchangers.
