Clad Aluminum Brazing Sheet

A convenient method of preplacing filler metal is by using a brazing sheet an aluminum alloy base metal coated on one or both sides.

Clad aluminum brazing sheet.

The fuselages of civil aircraft are for the most part made from 2024 alloy sheet clad on either surface with a low composition aluminum alloy a 1050 or 1070 alloy for example. Contact lynch metals inc. Aluminium brazing sheet is manufactured by roll bonding techniques to clad a core alloy ingot on one side or both sides with a low melting alsi alloy. The thickness of the cladding on each surface may according.

Heat treatable or core alloys composed mainly of manganese or magnesium are also used. To the thickness of the core sheet typically represent between 1 and 15 of the total thickness. To improve the brazing and durability properties of the heat treatable alloys a multilayer clad aluminum material was developed. Braze interlayer core cladding of pure al almg si total thickness this paper describes brazing experi.

Depending on the desired final properties the core is either homogenized or not before the cladding operation. This material known as mul ticlad has improved properties due to reduced silicon penetration. We have developed and are refining a variety of products of this sort. Our clad alloy brazing sheet ranges from 0 5mm up to and including 5 0mm thickness with cladding ratios ranging from 5 to 15 one two side clad 4343 4045 brazing alloy.

Aluminum clad brazing sheet is a composite material typically consisting of a core alloy and one or more liner alloy that are metallurgically bonded clad to the core alloy. Aluminum clad brazing sheet is a composite material typically consisting of a core alloy and one or more liner alloy that are metallurgically bonded clad. 1075 lousons rd union nj 07083 p. Brazing brazing sheet some aluminum sheet products are made up of a strong core alloy that is clad with a thin layer of high silicon alloy which has a much lower melting point than the core.

Cladding an aluminum silicon alloy with a brazing sheet provides an aluminum alloy that has the thin walls necessary for use in automobile heat exchangers as well as such desirable characteristics as high strength corrosion resistance and formability. Some of our clients. A third method of applying brazing filler metal is to use a paste mixture of flux and filler metal powder. As an alternative one side can be clad with a non braze alloy e g.
