QuCu80 Bobbin – Laser Welding Wire Aluminium Bronze CuMn13Al8 / 2.1367 – for Ampco Bronzes, 250 HB

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 materialsCu-Al multi-component bronzesAmpco and Ampcoloy alloys (mould inserts)Cladding on cast iron and steelBuild-ups on grey iron, e.g. drawing toolsTypical applicationsAmpco bronze mould inserts — build-up, crack repair, joiningDrawing tools and build-ups on cast ironComponents under sliding loadSea water and cavitation-loaded componentsProperties and advantages250 HB — the strongest of quada's three aluminium bronzesWeld metal: Re 400 MPa · Rm 650 MPa · A 10 %Sea-water and cavitation resistantGood sliding properties — also for bearing surfacesRod form advantage: Constant wire feed when repairing cracked mould inserts.Rod form: Rod lengths 1000 mm and 333 mm, Ø 0,2 mm – 0,8 mm.

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 materialsCu-Al multi-component bronzesDissimilar joints CuAl bronze to steelCladding on cast iron and steelBuild-ups on tool steel and cast alloysTypical applicationsBronze-to-steel dissimilar jointsCladding welds on steel and cast ironJoint welds on CuAl bronzesSliding surfaces, sea water and cavitation loadProperties and advantagesA 30 % elongation — the most ductile weld metal of the range140 HB, Re 270 MPa · Rm 530 MPaSea-water and cavitation resistantGood sliding propertiesBobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,3 mm – 0,8 mm.
