Whether you’re a materials engineer looking for the perfect alloy or a manufacturer curious about its potential uses, we’ve got the answers. Let’s dive right in!
Overview of Ni60 Powder
Ni60 powder, also known as Nickel 60, is a nickel-based alloy with 60% nickel content. This material is renowned for its superior wear resistance, high hardness, and oxidation resistance at elevated temperatures. It is often used in thermal spraying, welding, and powder metallurgy to create components that need to endure abrasion, corrosion, and high-stress environments.
So, what makes Ni60 powder so special? It’s all about the combination of elements. With a mix of chromium, silicon, boron, and other elements, Ni60 powder has a self-fluxing ability that allows it to form a dense, strong layer when applied to surfaces. This makes it an ideal choice for hard-facing, repairing worn parts, and creating new components that need to last in harsh conditions.
