瑞典ESAB伊薩銅焊絲OK Tigrod 19.49 ERCuNi白銅銅鎳焊絲SCu7158
Bare Cu-Ni rods for welding similar alloys, such as 90Cu10Ni, 80Cu20Ni and 70Cu30Ni alloys. The addition of nickel strengthens the weld bl and improves corrosion resistance, particularly to salt water. The alloy is used for the overlay welding of steels and is widely used for welding Cu-Ni components for desalination plants.
OK Tigrod19.49
適用于焊接諸如90Cu10Ni, 80Cu20Ni 和70Cu30Ni等類似合金的裸銅鎳焊絲。鎳含量可提高焊縫金屬強(qiáng)度,并改善抗腐蝕性能,尤其是鹽水條件下的抗腐蝕性。該合金可用于鋼材堆焊,并廣泛用于海水淡化工廠銅鎳合金組件的焊接。
