Думаю фразой all Aluminum Alloys все сказано.  |
Вот такое вот предлагают:
Aluminum soldering rod for use with propan-butan gas heater. The product is capable of making extremely high-strength soldering for aluminum. It creates molecular bond by soldering together two pieces of work or when materials are to be complemented.
+! There is a possibility of tin based soldering, such as: Copper + aluminum, etc.
The "oxide exempted" suface of the aluminum workpiece where to be soldered is needs to be heated locally, on the place of the soldering, up to 380-400 degrees C by using warming flame and then we cover the workplace with a thin layer, a small amount of the rod. We add soldering tin to the still liquid Alu Forr material and after by placing the tin covered material (copper, etc.) in it we get tin based soldering.
Fields of application:
- Aluminium profiles, window frames, ladders, railings, for soldering broken parts of machinery / equipment, great material suitable substitution.
- Aluminum casting of vehicles, agricultural machinery, motorcycle engine block, aluminum tools, kitchen equipment, repairing and soldering of aluminum casts components of household appliances.
Aluminum blocks:
The occasion of milling in order to reduce material losses by soldering together two different sizes of material composition, the working time and costs can be reduced.
Usage:
The preparation of the surfaces of workpieces. Using different abrasives (sandpaper, wire wheel, wire brush, etc.). "Oxide exempting" of the desired solder surface. If two surfaces are to be soldered together theseoperations should be performed on both two surfaces!
Application of the material:
Using gas flame (Pb), the material substances are heated at work-temperatures 717 -- 737F (380-400 degrees C) while adding the aluminum rod to the surface (surfaces) and make a coat using a wire brush to spread. Then place onto each other the two solder-coated surfaces of the work piece and solder them by heating with flaming torch. After solidification of the solder, in terms of mechanical properties, much superior to the mechanicalproperties of the workpiece. This should be considered during any post-processing.
Solder alloy types:
Al-Cu, Al-Mg, Al-Si Al-Zn! (in other name Zamak 1-7)

Сорри что без перевод - но основное я выделил. Я так понимаю - Al-Cu это как раз дюраль?
