PHILARC AL-BRONZE CuAl-A2

AWS Specification: AWS A5.6 E CuAl-A2

JIS Specification: NONE

Other Specification: NONE

 

I. APPLICATIONS:

Applications for PHILARC AL-BRONZE CuAl-A2 include: building up bearing surface, joining and fabricating copper alloys, overlaying for resistance to corrosion and erosion and general maintenance and repair welding such as:

Ship propellers           Copper to steel            Paper mill rolls

Cast iron                     Bearings                      Motor bases

Malleable iron              Bushing                       Tin plate mill rolls

Cast iron to bronze     Pump housings           Impellers

Steel to bronze           Condenser boxes        Valve seats

Aluminum bronze       Hydraulic pistons         Gears       

Silicon bronze            Brake drums                Mixer arms

Manganese bronze    Tractor gear housing   Press rams

Cupro-nickel               Idler pulleys                 Lance Heads

Tool steel                    Pickling hooks             Turbine runners                                                                                                  

II. DESCRIPTION:

PHIILARC AL-BRONZE CuAl-A2 aluminum bronze is the most versatile welding electrode in this family of alloys.

PHILARC AL-BRONZE CuAl-A2 contains an additive to inhibit inter-granular stress corrosion cracking. This is particularly important when welding on C61300 and C61400 base metal.

PHILARC AL-BRONZE CuAl-A2 will weld and join many ferrous and nonferrous metals and combinations of dissimilar metals. These metals include the more weldable grades of cast iron, high and low carbon steels, copper, bronzes and copper-nickel alloys.

III. NOTES ON USAGE:

• Preheat at 250~300ºC is increasing in the case of welding of brass.

• The interlayer temperatures varies in accordance with the preheat temperatures.

• Keep the arc length as short as possible and don’t use too much weaving.
