Aluminium brazing material production
Complex assemblies can be turned into single unit by just one pass
through a brazing furnace & period; Aluminium brazing
facilitates the joining of parts with a near-eutectic Ai-Si filler
alloy, the liquid temperature which is about 50C lower than that of
the core & period; In serial heat exchanger production the
filler alloy is supplied via a thin clad on a core alloy;
Compound Material
Aluminium brazing material is a sophisticated multi-layer compound
consisting of a core alloy which provides the stength and life
cycle requirements of the heat exchanger and a clad brazing filler
& period; A one-sided protection layer can also be clad &
comma; in order to prevent water-side radiator
corrosion.
During brazing: only the clad brazing alloy melts; while the core
alloys remain solid & period; The design and the applied
materials of the heat exchanger are adjusted to optimize the
brazing result regarding the required post braze mechanical
properties as well as the corrosion resistance & period;
Roll cladding
Two basic cladding techniques, roll bonding and cast cladding, have
become established industrially & period; Roll cladding is a
solid-state welding process; which is used to join similar and
dissimilar aluminium alloys; and represents the primary method of
manufacturing fuselage skin sheet for aircraft; bright products and
brazing sheet for automotive applications; The cladding layers are
attached to the core slab by welding and metallurgical bonding
using hot rolling; The cast cladding technique is based on a
conventional direct chill mould modified in order to allow multiple
metal streams to be casted into one single ingot.
