4A13 aluminum brazing foil

4xxx series aluminum alloys are aluminum alloys with Si as the main alloying element. Most of the alloys are heat-treated non-strengthable aluminum alloys. Only alloys containing copper, Mg and Ni can be strengthened by heat treatment. This series of alloy has high Si content, low melting point, good melt fluidity, easy to feed, and will not make the final product brittle, so it is mainly used to make aluminum alloy welding additive materials, such as brazing plates, a welding rod And welding wire.
