Nowadays Aluminum is increasingly used as an alternative to steel or other metals. This is due to its many advantages such as lightweight, ease to produce complex shapes through casting, lower cost compared to other metals, etc. But from the point of view of repairing, it shows some drawbacks that make it difficult to weld. The two most important are:

• The absence of color changing ( as a temperature guide) when heated during welding. It doesn't turn red like other metals, and once reached 650 °C, it liquefies quickly and the piece is irreparably damaged, instead to be repaired.
• The aluminum oxide which forms quickly in contact with air on its surface. This oxide layer is very hard and has a melting temperature of over 2000 °C, which is more than three times that of aluminum. So it must be removed to allow welding, but it is difficult to do. In addition, it tends to absorb hydrogen from moisture, oil, paint or dirt, causing porosity during welding.

For these troubles in Aluminum welding, most workshops in the past have recommended to replace broken parts with expensive new ones, rather than repairing them. But fortunately time have changed! Now is no more necessary to throw away broken parts, because MALLOY has developed a range of technologically advanced products to easily and quickly repair all aluminum parts: MALLOY 56 and MALLOY 52 for flame applications, and MALLOY 550 for electric arc.

MALLOY 56 is a universal brazing alloy for all aluminum, to be applied with its special FLUX. This flux has the ability to eliminate the oxide and dirt on the surface, but also to indicate the right temperature to apply the rod, which is reached when the flux changes from powder to liquid state. This temperature is about 150°C lower than aluminum, thus offering a very high safety margin. In addition MALLOY FLUX 56 increases the fluidity of the alloy, allowing capillary brazing, very useful in repairing applications especially on thin sheets or pipes joints.

MALLOY 52 is a special soldering alloy that melts at 200 °C and can join aluminum, and all other metals, including dissimilar combinations between them. In particular, it is able to join all zinc die cast alloys. It is applied in conjunction with its special flux MALLOY 52, which acts as deoxidizer and temperature guide to indicate the right moment to apply the rod, which occurs when the liquid flux start bubbling changes its color.

MALLOY 550 is a universal electrode with a special long shelf life flux coating for welding all aluminum. It can be easily applied with a DC welding machine, or even with flame.

With these MALLOY special products you can easily and quickly repair any piece of aluminum, without having to replace it with a new one.

This means SAVE TIME AND MONEY!
