What is Nickel? Nickel is one of five metals in the ferromagnetic group, also known as Nickel, with the chemical symbol Ni. Nickel is white-silver in color, usually in the form of compounds. Because in its compound form it is inert to oxygen gas while in its pure form it is reactive to oxygen. Nickel is hard, glossy and smooth, malleable and malleable, melting at a high temperature of 1455oC. Characteristics of Nickel based alloy powder: Nickel-based alloy powder is a material composed mainly of Nickel and some other alloys. Nickel-based alloy powders are known for their excellent corrosion resistance, oxidation resistance and durability. They are often used in high temperature environments due to their superior heat resistance. Nickel alloy is resistant to metal corrosion, is ductile, has electronic properties and is attractive, it can withstand harsh environments, providing performance at temperatures > 1000oC. Apply for different technology: – HVOF / HVAF – Plasma Transfer Arc (PTA) – Laser Cladding Popular types of Nickel based powder: Nickel (Ni) and Chromium (Cr) alloys: have extremely effective corrosion resistance, heat resistance, and great bearing capacity. Alloys between Nickel and Chromium are now quite popular, especially grade 625. – Inconel 625 – Inconel 718 Name Ni C Si B Fe Cr Mo Others Typical HRC Typical Hv PD Ni-20 Bal. 0,03 2,4 1,4 0,4 – – – 20 230 • For surface welding on cast iron and bronze • Ideal for glas moulds PD Ni-32 Bal. 0,25 3,0 1,0 2,4 5,6 – Al=1,0 32 310 • For surface welding on cast iron and bronze • Ideal for glas moulds and oil & gas mud motor bearings PD Ni-38 Bal.
