Non-Ferrous Materials

Why Non-Ferrous Materials Matter in Powder Metallurgy

Non-ferrous metals, such as brass, bronze, and copper alloys, are prized for their corrosion resistance, electrical and thermal conductivity, machinability, and aesthetic appeal. Unlike ferrous materials, they contain no iron, which eliminates rusting and allows them to perform reliably in demanding environments.

Atlantic Sintered specializes in the pressing and sintering of non-ferrous powders to create durable, high-density components. Our process supports both single-press and double-press/double-sintering techniques to enhance density, strength, and dimensional precision.

Benefits of Using Non-Ferrous Powdered Metal Parts:

• Excellent corrosion resistance (ideal for marine, outdoor, or humid environments)
  
• Natural antimicrobial properties (especially for brass)
  
• Superior electrical and thermal conductivity (used in electrical terminals and heat sinks)
  
• Good wear resistance and self-lubricating potential
  
• Precision shapes with minimal material waste
  
• Attractive finish with optional secondary plating or coating
  
  

Our non-ferrous PM components are used in diverse industries, including lock and hardware, electrical systems, home appliances, and consumer products.

Typical Non-Ferrous Applications We Manufacture

Atlantic Sintered’s non-ferrous capabilities cover a wide range of industries and use cases. Our engineering and production teams collaborate closely with customers to deliver custom solutions that meet form, fit, and function—every time.

Common Applications Include:

Over-Molded Handle Inserts

Brass or bronze inserts that are molded into plastic or polymer handles to provide structural reinforcement, metallic feel, or grounding capabilities. Widely used in power tools, appliances, and handheld equipment.

Lock Cylinders

Used in residential, automotive, and commercial locking systems, these precision brass components offer excellent machinability and corrosion resistance, supporting both key-cut and electronic lock formats.

Electric Terminal Connectors

Non-ferrous powdered metal terminals provide reliable electrical conductivity and can be designed to fit into PCB boards, motor housings, or connector systems, improving durability and reducing cost.

Counterweights

Brass and bronze counterweights are ideal for appliances, HVAC systems, and electronic devices that require fine balance with compact weight density. Powder metallurgy enables precision shaping without the need for secondary machining.
