Nickel Brass in Additive Manufacturing (3D Printing): Recent Advances

Nickel brass, an alloy known for its high strength and excellent wear resistance, has been a material of choice in various engineering applications. With the advent of additive manufacturing, also known as 3D printing, nickel brass has found a new frontier in which its properties can be exploited to create complex and high-performance components. This article delves into the recent advancements of nickel brass in the realm of additive manufacturing.

Additive manufacturing is a process that involves the layer-by-layer deposition of material to build a three-dimensional object from a digital model. This technology has revolutionized the way we approach design and manufacturing, allowing for the creation of intricate designs that would be impossible or too costly with traditional methods. Nickel brass, with its unique combination of properties, is an ideal candidate for this technology.
