16 Product Uses and Applications. Meta-Braze ™ Al filler metals are intended for joining aluminium alloys – the 1000 series (e.g. 1100), 3000 series (e.g. 3003, 3004), 5000 series and some 6000 series alloys (eg.6061, 6031, 6951). These products are used in the manufacture of automotive components and aluminium heat exchangers. VBC Group offer a number of Meta-Braze Advanced ™ forms of
Brazing aluminum with Fusion paste braze alloys has been popular since 1982. There are four basic challenges when brazing aluminum: • Brazing Alloys Melt Close to Melting Point of Base Metals. • Aluminum Oxides Form Rapidly and Are Very Tenacious. • Control of Heat During
the melting temperatures of the aluminium alloy itself. Generally, brazing of the various aluminium alloys is restricted by the available filler alloys which are based on the binary system Al - Si. Alloys of type 2XXX and 7XXX are, therefore, not brazeable as their solidus/liquidus temperature are too low for the filler
Cladding Alloys. Brazing sheet comprises of a core alloy clad on 1 or 2 sides with a lower melting aluminum-silicon (Al-Si) alloy. This thin layer, usually makes up 5 % to 10 % of the total thickness of the brazing sheet. It melts and flows during the brazing process, to provide upon cooling a metallic bond between the
Aluminum brazing alloys are employed to bring an all-aluminum structure with good corrosion resistance and great strength. The brazing temperature needed for aluminum brazing is determined by the melting points of the base metal and the brazing filler metal. You can use aluminum braze to repair holes, cracks, rivets, leaks, threads, broken ears
A-54N is a silver brazing alloy suitable for furnace brazing due to its low zinc content. Its broader melting range (250°F) is helpful where clearances are not uniform. Has the lowest brazing temperature, best wetting, and best flow of all the cadmium-free alloys. Good for
Meta-Braze ™ 4310 gives rise to minimal parent metal erosion. Meta-Braze ™ 4770 – this alloy is a low-melting, free-flowing filler metal which can be used for thin walled structures such as honeycomb parts and thin walled tube assemblies. Meta-Braze ™ 4720 –
The \"working\" elements of active brazing alloys are titanium and zirconium. Because Ti and Zr are very strong acceptors of oxygen (and there is obviously a lot of oxygen present in oxide-form within the sintered matrix of oxide-base ceramic materials), the joining process will depend very much on the ability of titanium/zirconium to react (at brazing temperature) with oxides that are present
SKA’s H-series (homogeneous brazing filler metals) features the uniform mixture of a filler metal and a flux. 1. A perfect solution to defects caused by the tolerance of a flux content The chronic problem with aluminum filler metals is the tolerance range of flux contents: ±5 % or

Aluminum brazing alloys typically contain silicon (under the BAlSi classification) or zinc and melt below the solidus of brazeable base metals. Wire and rod are used for manual applications, and preformed rings or shapes for furnace operations. A flux must be used to wet the base metal and inhibit surface oxides unless brazing in a vacuum. °F
Aluminium-silicon and aluminium-zinc alloys for aluminium low temperature brazing.Aluminium-zinc alloys are fitted also for copper-aluminium and steel-aluminium brazing. These alloys are available in different formats such as wires and roads, foils and sheets, flux cored wires, rods and rings, preformed, powder and pastes.Using fluxed cored wires it’s not needed the flux residues

Featuring Holtite Alloys and Miter-Al-Braze Alloys for Aluminum Metal Joining 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
1680°F/ 915°C. RBCuZn-D. Torch. Used for brazing Tungsten carbides, copper alloys, nickel alloys, stainless steels, carbon steels, and cast iron. Good color match to stainless steel. A superior alternative in terms of color match, joint strength and mability. This is a low cost alternative to silver brazing
When Al-0-1.2%Si alloys that have a solidus temperature that is higher that their brazing temperature were used, the level was almost constant irrespective of the Si content of the base
Brazing is a process by which non-ferrous filler metals or braze alloys are melted between two or more close-fitting base metal parts to form a joint. The technique involves heating components above the braze alloy melt temperatures and below the melting temperature of the base metal, allowing capillary action to distribute the molten filler
PROCEDURES FOR BRAZING APPLYING THE BRAZING ALLOY APPLY THE BRAZING ALLOY Feed the alloy into the joint between the tube and the fitting. Only after the base metals have been heated to brazing temperatures should the filler metal be added. At that time, the flame may be deflected momentarily to the tip of the filler metal to begin the melting
