Product Description

 Introduction:HBWH-70G-1 700MPa grade high strength copper wire, using rich argon gas protection, through the low C,

high Mn, Ti, Cr processing and Ni alloy elements such as solid solution strengthening, grain refinement, the weld seam with

high strength and high toughness, and stable arc, little splash, and can be suitable for the full range of welding.

Widely used in the welding of coal mine machinery, heavy machinery, vehicles, shipbuilding, container and other 700MPa grade

high strength steel and low alloy structural steel (such as Q500, Q550) .
