QuCu81 Bobbin – Laser Welding Wire Aluminium Bronze CuAl8Ni2 / 2.0922 – Ductile, 140 HB
QuCu81 is the ductile one of the three aluminium bronzes: EN ISO 24373 S Cu 6327 (CuAl8Ni2Fe2Mn2) · material no. 2.0922. At 140 HB it is the softest — in return it offers 30 % elongation, three times that of QuCu80.
That toughness is the reason to choose it: in dissimilar joints between CuAl bronze and steel, and in joints between differing materials generally, the seam is under permanent stress because both sides expand differently. Ductile weld metal absorbs that; strong weld metal cracks. Equally suited to cladding on steel and cast iron. Sea-water and cavitation resistant, good sliding properties.
Recommended base materials
- Cu-Al multi-component bronzes
- Dissimilar joints CuAl bronze to steel
- Cladding on cast iron and steel
- Build-ups on tool steel and cast alloys
Typical applications
- Bronze-to-steel dissimilar joints
- Cladding welds on steel and cast iron
- Joint welds on CuAl bronzes
- Sliding surfaces, sea water and cavitation load
