The center metal is often copper; its role is to act as a carrier for the alloy, to absorb mechanical stresses due to e.g. differential thermal expansion of dissimilar materials (e.g. a carbide tip and a steel holder), and to act as a diffusion barrier (e.g. to stop diffusion of aluminum from aluminum bronze to steel when brazing these two).
Similar to BAg-13. Tends to liquate. Can be used for wide gap joints. Can be used with flux, but mostly used for fluxless furnace brazing of stainless steel in dry hydrogen.

Aluminium alloys are often used due to their high strength-to-weight ratio, corrosion resistance, low cost, high thermal and electrical conductivity.There are a variety of techniques to join aluminium including mechanical fasteners, welding, adhesive bonding, brazing, soldering and friction stir welding (FSW), etc. Various techniques are used based on the cost and strength required for the joint.
Fluxes are also used in foundries for removing impurities from molten nonferrous metals such as aluminium, or for adding desirable trace elements such as titanium. As reducing agents, fluxes facilitate soldering, brazing, and welding by removing oxidation from the metals to be joined. In some applications molten flux also serves as a heat ...
In short, oxy-fuel equipment is quite versatile, not only because it is preferred for some sorts of iron or steel welding but also because it lends itself to brazing, braze-welding, metal heating (for annealing or tempering, bending or forming), rust, or scale removal, the loosening of corroded nuts and bolts, and is a ubiquitous means of ...
Hiduminium or R.R. alloys (2% copper, iron, nickel): used in aircraft pistons Hydronalium (up to 12% magnesium, 1% manganese): used in shipbuilding, resists seawater corrosion Italma (3.5% magnesium, 0.3% manganese): formerly used to make coinage of the Italian lira
On average, the U.S. imports more than 2 million metric tons of steel mill products per month, according to data by the Department of Commerce’s International Trade Administration, but only ...
An amorphous brazing foil (ABF) is a form of eutectic amorphous metal that serves as a filler metal in brazing operations. ABFs are composed of various transition metals (including nickel, iron, and copper) blended with metalloids like silicon, boron, and phosphorus.
