QuLPA-Ni76 Powder – Laser Cladding Powder Hastelloy C276 / 2.4819 (ERNiCrMo-4) – Acids, Buffer Layers

QuNi76 is a highly corrosion-resistant laser welding wire of the nickel-base alloy Hastelloy C276 (base material 2.4819 / NiMo16Cr15W, Alloy C-276, UNS N10276). As a filler metal it corresponds to 2.4886 (DIN EN ISO 18274 S Ni 6276, AWS A5.14 ERNiCrMo-4). Its high molybdenum content of 16 % makes it resistant to a wide range of corrosion in oxidising and reducing media alike — particularly against acids.Recommended base materials2.4819 — Hastelloy C276 / NiMo16Cr15W / Alloy C-276 / UNS N10276 (primary material)Ni-Mo-Cr-W alloys (similar and related)Joints with unalloyed, low-alloy and high-alloy steel as well as cast steelTypical applicationsChemical process industry — acids, oxidising and reducing mediaDissimilar nickel-steel joints — joining welds with unalloyed, low-alloy and high-alloy steel/cast steelBuffer layers ahead of dissimilar build-up weldsPlant, apparatus and vessel constructionEnvironmental engineering and flue-gas cleaningProperties and advantagesResistant in oxidising and reducing media alikeGood resistance to acids (16 % molybdenum content)High resistance to pitting, crevice and stress corrosion crackingProven for dissimilar joints between nickel alloy and steelMechanical properties (pure weld metal, 20 °C): Re 470 MPa | Rm 780 MPa | A 35 %Bobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,4 mm – 0,6 mm.

QuLPA-Ni24 is the nickel-base cladding powder for matching build-ups on Inconel 625 / 2.4856 and similar nickel-base materials (NiCr22Mo9Nb).Its microstructure is austenitic and non-transformable — hence the unusual span: high strength and toughness up to 1100 °C and at the same time toughness down to −196 °C. Molybdenum and niobium in the NiCr matrix give, per the datasheet, exceptional fatigue strength, plus favourable long-term creep values and resistance to stress and hot cracking. Hence its use in aerospace and the chemical industry. At 17 HRC the deposit is soft — it delivers corrosion and temperature resistance, not hardness.Recommended base materials2.4856 — Inconel 625 / Alloy 6252.4858 — Alloy 8251.4539 (904L), 1.4529, 1.4876 (Alloy 800)ISO 20172: NiCr22Mo9Nb with group 1.1 / 1.2Typical applicationsAerospaceChemical industryComponents up to 1100 °C and cryogenic use down to −196 °CCorrosion protection cladding by laser metal deposition (LMD)Properties and advantagesStrong and tough up to 1100 °C, tough down to −196 °CResistant to stress and hot crackingExceptional fatigue strength thanks to Mo and Nb17 HRC (15–19 HRC).

QuLPA-NiGuss is the nickel-base cladding powder for castings — designed for the two material groups that are hardest to repair with matching filler metals: cast iron and bronze alloys.Nickel is the key here: the weld metal stays tough and crack-resistant instead of hardening the way a matching cast-iron filler would. At 32 HRC the deposit sits deliberately in the middle range — hard enough for functional surfaces, soft enough to be machined afterwards. Particle size 45–150 µm for classic nozzle-based LMD.Base materialsCast ironBronze alloysApplicationsCladding and repair of cast componentsRestoration of bronze bearing surfaces, bushings and sliding elementsRebuilding worn functional surfaces to sizeCoating of cast housings and pump partsAdvantages32 HRC — machinable deposit, no post-hardening requiredNickel base: tough, crack-resistant weld metal on brittle castingsCovers cast iron and bronze with a single powderParticle size 45–150 µm — standard fraction for nozzle-based LMDPowder form: grain size 45 - 150 µm — for laser metal deposition (LMD).

QuLPA-AlSi10Mg is the aluminium cladding powder: AlSi10Mg · material no. ~3.2823.Silicon (9–11 %) makes the powder readily weldable, magnesium (0.2–0.45 %) makes it age-hardenable — per the datasheet a heat treatment following the T6 cycle is applicable. That is the point: the deposit can be brought up to strength afterwards (Rm 400 MPa · Rp0.2 230 MPa · A 7 %). The grain is spherical (−45 +15 µm) and therefore free-flowing — the precondition for even powder feeding.Recommended base materialsBuild-ups and welds on aluminium alloys with approx. 10 % SiAlSi10Mg die castingsTypical applicationsRepair of AlSi10Mg castingsParts subsequently T6 heat treatedLaser metal deposition (LMD) on aluminiumProperties and advantagesT6 heat treatment applicable — strength can be set afterwardsRp0.2 230 MPa · Rm 400 MPa · A 7 %Spherical grain shape — even powder feedingGrain size −45 +15 µmPowder form: grain size -45 +15 µm — for laser metal deposition (LMD).
