GB SAI 5087
Conform to: AWS ER5087
EN ISO S AL 5087 (AlMg4.5MnZr)
Description:
ER5087 is kind of magal welding wire with Mg, Mn content. It has good strength with Cr, Zr element inside, and the density was futher inceased. It has better corrosion resistance and thermal cracking resistance, and the strength is also impoved.
Application:
It is used for aluminum magnesium, aliminum magnesium silicon alloy argon arc welding, gas protection welding. In aluminum magnesium and aluminum magnesium silicon alloy welding and aluminum magnesium casting repair welding, also can be used for aluminum magnesium manganese alloy and aluminum magnesium silicon alloy welding, it is the largest amount of aluminum alloy welding wire.
cryogenic tank, railway vehicles. offshore platform industry, marine engineering manufacturing and maintenance, shipbuilding and other high strength structural steel.
auto parts. autobody panel, heat exchanger/radiator, brazing of aluminum sheet, extruder and casting.
