The automotive industry is one of the largest industries in the world, encompassing the design, development, production, marketing and sale of motor vehicles. The industry has specific needs, including lightweight and durable materials that can improve fuel efficiency, reduce emissions and enhance vehicle safety. Metal powders play a critical role in meeting these needs by offering unique properties that can be tailored to meet specific automotive requirements.

Why Powders?

Metal powders are used extensively in the automotive industry, particularly in the manufacture of engine components such as pistons, connecting rods and cylinder heads. They are also used in the manufacture of transmission gears, brake components, suspension systems and structural parts. Metal powders are valued for their high strength-to-weight ratio, wear resistance and excellent machinability, making them ideal for these applications. 

Metal powders produced by ATO Lab Plus ultrasonic metal powder atomizers are highly sought after by the automotive industry for their exceptional properties. ATO metal powders have a very narrow particle size distribution, high particle sphericity and low oxygen content, making them ideal for use in critical automotive components. The powder's uniformity and consistency ensure excellent flowability, which is important for consistent part production. The high-quality powders produced by the ATO Lab Plus also ensure minimal material waste and excellent process repeatability. 

A wide range of alloys are used in the automotive industry, depending on the specific application. Aluminum and its alloys are widely used because of their low density, high strength, and excellent corrosion resistance. Magnesium alloys are also used to make lightweight components, while copper alloys are used for electrical connections. Steel and its alloys remain the most widely used metals in the automotive industry, and nickel-based alloys are used for high-temperature applications.

Examples of Metal powder applications
in Automotive industry

Piston manufacturing

Aluminum alloy powders are used to produce lightweight, high-strength pistons that improve fuel efficiency and reduce emissions.

Brake components

Copper alloy powders are used in the manufacture of brake pads and linings due to their excellent wear resistance.

Exhaust systems

Stainless steel powders are used in the manufacture of exhaust systems due to their high temperature and corrosion resistance.

Transmission Parts

Metal powders such as iron and steel are used to make transmission gears, shafts and housings.

Fuel Injection Components

Metal powders such as copper and stainless steel are used in the manufacture of fuel injection components such as injectors and fuel rails.

Electrical connections

Copper powders are used in the manufacture of electrical connectors due to their excellent electrical conductivity.
