Umbes 4047 Alumiiniumi sulam (Al, Ja, Fe, Koos, Zn, Mn, Mg)

4047 Alumiiniumisulam on alumiiniumist räni kõvajoodis- või täitesulam, millel on hea korrosioonikindlus. Peamine erinevus sulami vahel 4047 ja selle AL4043 vaste on selle suurem ränisisaldus. Koos 11-13% räni, AL 4047 kasutatakse tavaliselt siis, kui konkreetse remondi või tootmise jaoks on vaja suurt voolavust ja väiksemat kokkutõmbumist ja kuumpragunemist. Lisaks, 4047 sobib kõrgetel temperatuuridel, mistõttu on see eriti kasulik autotööstuses osade ja mootoriplokkide jaoks. Other applications include welding filler wires, lekkivad tihedad liigendid, housing requirements, aknaraamid, liners such as laser welded covers for microwave integrated circuits, and other similar devices.

Brazing is a metal joining process whereby a filler metal is heated above the melting point and distributed between two or more close fitting parts by capillary action. The filler metal is brought slightly above its melting ( liquidus ) temperature while protected by a suitable atmosphere, usually a flux. It then flows over the base metal (known as wetting) and is then cooled to join the workpieces together. It is similar to soldering, except the temperatures used to melt the filler metal are higher for brazing. A variety of alloys are used as filler metals for brazing depending on the intended use or application method. Üldiselt, braze alloys are made up of 3 or more metals to form an alloy with the desired properties. The filler metal for a particular application is chosen based on its ability to: wet the base metals, withstand the service conditions required, and melt at a lower temperature than the base metals or at a very specific temperature.
