Silver Brazing Foils

Product Details:

ALFA - 203 is very versatile, high strength and is free flowing. It can be used to join a wide range of base materials.

Product Details:

ALFA - 207 may be used in brazing operations, requiring a low temperature, quick and complete penetration and neat joints of high strength that needs little or no finishing. It is used where joints are closely fitted and where it is desired to employ a single alloy effective in wide range of applications. It may be used in brazing steel, copper, brass, gunmetal, tin bronzes, aluminium, manganese bronzes, copper nickel alloys and nickel silver.

Product Details:

ALFA - 115 is extremely fluid at brazing temperature. It provides more strength to joint than ALFA105.

Product Details:

ALFA - 202 is very versatile, high strength, free flowing and exhibits low melting points. It can be used to join a wide range of base metals besides being economical.

Product Details:

ALFA - 205 is a general purpose alloy which has highest joint strength and also provides resistance to corrosion in chlorine, sulphur and steam environments.

Product Details:

ALFA-404 is used for brazing carbide tip brazing. Similar to ALFA-405, but higher brazing temperature is required. It flows freely and does not contain cadmium.

Product Details:

ALFA - 208 is free flowing and is suitable for general purpose work requiring higher brazing temperature. Its melting range is helpful where joint clearances are not uniform. Unless heating is rapid, care must be taken , that lower melting constituents do not seperate by liquation.

Product Details:

ALFA-405 is particularly suitable for brazing carbide tool tips to tool shanks as it wets the carbide tool tip very satisfactorily. It has a wide wetting range, therefore, the solid and liquid portions do not tend to separate excessively. It is good filler metal for bridging gap. It has good corrosion resistant properties and is particularly suitable for brazing stainless steels also.

Product Details:

ALFA - 207A wide melting range limit its application because it is more prone to liquation. It is recommended for applications with slow heating rates. However, it has good fillet forming properties and has ability to bridge wider gaps.

Product Details:

ALFA - 204 is versatlie, high strength, free flowing and exhibits lowest melting points.

Product Details:

ALFA - 311Sn is a low melting filler metal and does not contain cadmium. It is ideal for furnace brazing. It is used by the dairy and food industry where cadmium free joints are required. This brazing alloy is less prone to cause stress cracking on stainless steel and some nickel alloys. After brazing it gives a closer match with whitish metals such as stainless steel.
