Meta-Braze™ Al 112 (4047)

Meta-Braze™ Al 112 – is the industry standard for joining of aluminium alloys. With the appropriate flux and careful consideration of the brazing parameters it can also be used to join aluminium to dissimilar metals such as steel or copper.

Available product forms include: Rods, rings, washers and preformed shapes, powder and paste.

Sheet is available in the following thicknesses: 0.025mm, 0.050mm, 0.075mm, 0.10mm, 0.125mm, 0.150mm, 0.20mm, 0.25mm, 0.30mm, 0.38mm, 0.5mm, 0.75mm, 1.5mm

No.7 & No.8 Clad Aluminium Brazing Sheet - 3003 Core / 4004 Cladding

No.7 clad aluminium brazing foil has 1-side of a 3003 alloy core clad with 4004 brazing alloy. No.8 clad aluminium brazing sheet has both sides clad with 4004 brazing alloy on a 3003 alloy core.

The 4004 brazing alloy conforms to BAlSi-7 which contains between 1-2% magnesium. The magnesium in the brazing alloy acts as a 'getter' in the brazing cycle removing residual oxygen and moisture and enabling vacuum furnace brazing. The typical brazing range for 4004 clad foils is 588-604°C.

No.8 sheet is available in thicknesses between .005” to .125”

The 4004 cladding thickness varies between 15% for thinner foils of 0.24", 10% for foils of 0.025" to 0.062" to 7.5% for the thicker foils of 0.063" or more.×

No.13 & No.14 Clad Aluminium Brazing Sheet - 6951 Core / 4004 Cladding

No.13 clad aluminium brazing foil has 1-side of a 6951 alloy core clad with 4004 brazing alloy. No.14 clad aluminium brazing sheet has both sides clad with 4004 brazing alloy on a 6951 alloy core. The aluminium alloy 6951 is widely used in aerospace applications.

4004 brazing alloy conforms to BAlSi-7 which contains between 1-2% magnesium. The magnesium in the brazing alloy acts as a 'getter' in the brazing cycle removing residual oxygen and moisture and enabling vacuum furnace brazing. The typical brazing range for 4004 clad foils is 588-604°C.

The 4004 cladding thickness varies between 15% for thinner foils of 0.24", 10% for foils of 0.025" to 0.062" to 7.5% for the thicker foils of 0.063" or more.×

No.11 & No.12 Clad Aluminium Brazing Sheet - 3003 Core / 4343 Cladding

No.11 clad aluminium brazing foil has 1-side of 3003 alloy, clad with 4343 brazing alloy. No.12 clad aluminium brazing sheet has both sides clad with 4343 brazing alloy on a 3003 aluminium alloy core.

The 4343 brazing alloy conforms to BAlSi-2 which contains between 6.8-8.2% Si and has no magnesium. These products can be used for aluminium brazing with an appropriate flux or with additional special measures they can be used for brazing in a vacuum furnace. Typical brazing temperature range is 593-621°C.

The 4343 cladding thickness varies between 10% for .090” and less, 5% for .091” and more.×

No.21 & No.22 Clad Aluminium Brazing Sheet - 6951 Core / 4343 Cladding

No.21 clad aluminium brazing foil has 1 side of a 6951 alloy core, clad with 4343 brazing alloy. No.22 clad aluminium brazing sheet has both sides clad with 4343 brazing alloy on a 6951 aluminium alloy core.

The 4343 brazing alloy conforms to BAlSi-2 which contains between 6.8-8.2% Si and has no magnesium. These products can be used for aluminium dip brazing or with additional special measures for brazing in a vacuum furnace. Typical brazing temperature range is 593-621°C.

These products are available in 36" x "72" sheets in the following thicknesses - 0.02", 0.032", 0.040", 0.050", 0.063", 0.080", 0.094", 0.125", 0.190"

The 4343 cladding thickness varies between 10% for .090” and less, 5% for .091” and more.×

No.23 & No.24 Clad Aluminium Brazing Sheet - 6951 Core / 4045 Cladding

No.23 clad aluminium brazing foil has 1 side of a 6951 alloy core, clad with 4045 brazing alloy. No.24 clad aluminium brazing sheet has both sides clad with 4045 brazing alloy on a 6951 aluminium alloy core.

The 4045 brazing alloy conforms to BAlSi-5 which contains between 9-11% Si, no magnesium and a controlled addition of titanium. These products can be used for aluminium dip brazing or with additional special measures for brazing in a vacuum furnace. Typical brazing temperature range is 588-604°C.

The 4045 cladding thickness varies between 10% for .090” and less, 5% for .091” and more.
