Sferisch nikkelpoeder, a revolutionary material with a near-perfect ball-like shape, is making waves in various industries. Imagine tiny, uniform nickel spheres – the building blocks for a new generation of technological advancements. This guide delves deep into the world of spherical nickel powder, exploring its properties, applications, advantages, limitations, and various models available.
Properties of Spherical Nickel Powder
Nickel powder, in its standard form, consists of irregularly shaped particles. But the magic happens when these particles are transformed into near-perfect spheres. This seemingly minor change unlocks a treasure trove of desirable properties:
- Hoge doorstroombaarheid: Imagine pouring sand – it flows freely due to the spherical shape of the grains. Spherical nickel powder behaves similarly, enabling smooth movement within machinery and during 3D printing processes.
- Hoge verpakkingsdichtheid: Imagine packing oranges in a box – irregular shapes leave a lot of empty spaces. Spherical nickel powder, like neatly arranged marbles, packs tightly, maximizing material usage and minimizing waste.
- Uitstekend geleidingsvermogen: Spherical particles offer a larger surface area compared to irregular shapes, enhancing their ability to conduct heat and electricity.
- Verbeterd sinteren: Sintering is a process that binds metal particles together. Spherical nickel powder sinters more efficiently due to its uniform shape and consistent contact points.
Composition and Key Characteristics
Sferisch nikkelpoeder, as the name suggests, is primarily composed of nickel (Ni) particles. However, depending on the desired properties, small amounts of other elements like copper (Cu) or carbon (C) might be added.
