QuCu80 TIG Welding Wire – Aluminium Bronze CuMn13Al8 / 2.1367, for Ampco Bronzes
QuCu80 TIG Welding Wire – Aluminium Bronze CuMn13Al8 / 2.1367, for Ampco Bronzes
QuCu80 is the strongest of the three aluminium bronzes: EN ISO 24373 S Cu 6338 (CuMn13Al8Fe3Ni2) · AWS A5.7 ERCuMnNiAl · DIN 8555 MSG 31 GZ 200 · material no. 2.1367. The weld metal reaches 250 HB — Rm 650 MPa.
Its home is mould inserts made of Ampco and Ampcoloy bronzes: these highly conductive tooling bronzes are used in die casting and plastic mould making because they dissipate heat quickly — and that is exactly where they crack and wear. Besides build-up and crack welding it suits cladding on cast iron and steel (e.g. drawing tools). Sea-water and cavitation resistant, with good sliding properties.
Recommended base materials
- Cu-Al multi-component bronzes
- Ampco and Ampcoloy alloys (mould inserts)
- Cladding on cast iron and steel
- Build-ups on grey iron, e.g. drawing tools
Typical applications
- Ampco bronze mould inserts — build-up, crack repair, joining
- Drawing tools and build-ups on cast iron
- Components under sliding load
- Sea water and cavitation-loaded components
Properties and advantages
- 250 HB — the strongest of quada's three aluminium bronzes
- Weld metal: Re 400 MPa · Rm 650 MPa · A 10 %
- Sea-water and cavitation resistant
- Good sliding properties — also for bearing surfaces
TIG advantage: For larger build-up areas and cladding. Ø 1.0–1.6 mm.
TIG form: for manual repair welding.
