ALUMINUM FLUX CORED BRAZING WELDING WIRE ALUMINUM FILLER WIRE

Specifications

As one of our most popular hit products, HZ-Al12 eliminates the need for a separate fluxing operation, which can result in a significant increase in productivity while minimizing flux exposure to your personnel and plant equipment. HZ-Al12 is different from common aluminum filler metal, which needs argon welding. Unlike ER4047 aluminum brazing wire requiring flux, HZ-Al12 could work directly in flame brazing or induction welding. Because of self fluxing, flux  and relative operations are not needed. Precise set proportion has avoided many problems provoked by adding flux when traditional manual welding applied. It improves welding quality, simplifies operation, increases producing rate, and realizes automation manufacturing. It needs no wash after welding, and has an advantage of little harm to base metal. The demanded amount from our custom is very large. 

Chemical Compositions(%): Si, Al, rare earth, fluoaluminate(flux).

Welding Temp.(°C):570-582

Color: Grayish-White

Specific Gravity: 2.66

Advantages and Usages:

1.Flux and relative operation are not need.

2.Good fluidity and smooth welding joint

3.No acid cleaning need.

HZ-Al12 will join 1100, 3000 and 6000 series of aluminum with torch, induction or atmospheric furnaces. HZ-Al12 is available with additional brazing alloy in the form of a fine diameter wire inside the core. This reduces the percentage of flux and increases the volume of alloy, which can be advantageous in some furnace brazing application.   

Method:

1. Sand the welding position and work piece ( oil, rust and oxide must be cleaned away).

2. Heat welding position evenly by moving welding torch.

3. When temperature reaches 570°C, flux cored rod should be added. Then rod melts, and make it flow into the joint evenly. 

4. When the welding seam full, move torch away.

5. Cool down.

Package:

We have two kinds of packing. Package one: the wire would be rolled into coils. 2Kgs/ coil, 5 Kgs/ coil. And we wind it with shrink film.  Package two: The wires would be rolled in a plastic spool. 2kgs/spool, 5 Kg/spool.
