Non-Ferrous Metal Powders
Introduction
Non-ferrous metal powders are a type of powder created from the processed materials of non-ferrous metals. Non-ferrous metals are metals that do not contain an appreciable amount of iron. This allows them to remain rust-resistant and unlike ferrous metals, non-ferrous metals are not magnetic. As a result, non-ferrous metals powders are ideal for applications that require corrosion resistance, for industrial and consumer products. They are extensively used as a component of a variety of products, from consumer electronics and automobile parts to aerospace components. In addition, non-ferrous metals powders can be used in the production of catalysts, refractory materials, abrasives and coatings.
Description
Non-ferrous metal powders are produced by a variety of extraction processes, such as milling, chemical precipitation, atomization and electrolysis. In general, these processes use a substance, such as water, as a medium in which to dissolve the desired non-ferrous metal and extract it in powder form. The resulting powder is dry, with a fine particle size, and is usually composed of spherical particles. The particle size is important as it affects the density of the powder and its properties. Non-ferrous metal powders may also be treated with additional compounds, such as lubricants, stabilizers and anti-oxidants, to increase their surface characteristics and reduce the risk of oxidation.
Types
The most common types of non-ferrous metal powders are aluminum, magnesium, nickel, tin, zinc and titanium. These powders can also be combined to create an alloy powder with specific properties. The most common alloy powders used in industrial and consumer applications are aluminum-magnesium, zinc-tin and nickel-titanium. Other types of non-ferrous metal powders include cobalt and brass.
Applications
Non-ferrous metal powders are used in a variety of applications, primarily because of their corrosion resistance. Aluminum, magnesium and zinc powder can be used as a base material for lightweight and heat-resistant applications. Nickel and tin powder can be used in the production of electronics components, such as capacitors, resistors and voltage regulators. Titanium powder is used in the aerospace industry due to its high strength-to-weight ratio and high temperature resistance. Non-ferrous metal powder alloys are often used in the production of automobile components and parts, such as wheels, brakes and suspension components. Other applications include the production of catalytic converters and fuel cells as well as coatings for decorative and protective purposes.
Conclusion
Non-ferrous metal powders are a vital component of many industrial and consumer products, due to its corrosion resistance, light weight, and thermal stability. There is a wide variety of non-ferrous metal powders available, including aluminum, magnesium, nickel, tin, zinc, titanium, cobalt and brass. Each type of powder has specific application in various industries, such as automotive, aerospace and electronics. In addition, non-ferrous metal alloys can be blended together to create an alloy powder with enhanced properties, suitable for various industrial and consumer products.
