High-Precision Brass CNC Machining
From Fathom

Brass is a metal alloy of copper that is ideal for CNC machining, thanks to its excellent mechanical strength and malleability. Its corrosion resistance and thermal conductivity make it ideal for pipes and valves. It’s also popular for its aesthetic qualities. Brass CNC machining is one of the many CNC machining services available from multiple Fathom locations.

What is
Brass CNC Machining?

Brass CNC machining produces high-quality, high-precision components with an aesthetic surface finish. This versatile material can be machined into a variety of shapes, including light fixtures, fittings, gears and hinges.

What Types of Material
Are Used in Brass CNC Machining?

Copper and zinc can be mixed with other metals to give brass a variety of qualities. Here are the types of brass Fathom offers as part of its CNC machining services:

Admiralty Brass – C443:

  • Sometimes called arsenical brass, C443 is alloyed with zinc and tin. Admiralty brass C443 has excellent corrosion resistance and heat transfer characteristics. Common applications of admiralty brass include distiller tubes, condenser plates, architectural applications, or any parts that may encounter salt or fresh water.

Architectural Bronze – C385:

  • Often referred to as C385 brass, 385 bronze is alloyed with copper, lead, iron and trace amounts of zinc. Architectural bronze 385 offers long-term durability and excellent corrosion resistance. Applications of 385 brass include shower doors, elevator trim, funeral urns, drawer pulls, valves and gun sights.

Brass Plate / Leaded Muntz Metal – C365:

  • Brass plate C365 is made from copper, zinc, tin and lead. Leaded muntz metal C365 is highly machinable, strong and corrosion-resistant. Applications of brass plate C365 include parts for the shipbuilding industry, condenser plates, and architectural components.

Commercial Bronze – C220:

  • Bronze 220 is made from copper, zinc and tin. Commercial bronze has good formability, corrosion resistance, strength and excellent color. Applications of C220 include lighting fixtures, kickplates, jewelry, medals, hardware, marine hardware, etc.

Free Machining Brass – C360:

  • Free machining brass C360 is made from copper and lead. 360 brass is used to make bar and brass rod items, including machine parts, couplings, circuit boards, industrial hardware and plumbing products.

German Silver / Nickel Silver – C770:

  • German silver is not made of silver but from copper, zinc and alloyed nickel. 770 nickel has a silver-like look with excellent strength, corrosion resistance, and electrical conductivity. German silver is often used for decorative applications.

High Leaded Brass – Engravers’ Brass – C353:

  • High leaded brass is made from copper, zinc, lead and trace iron. Engravers’ brass is stiff, machinable, polishable, and good for soldering. Applications of high leaded brass include hardware, drawer handles, nuts, gears, signs and placards.

Low Leaded Brass – C330:

  • 330 brass is made from copper, lead, iron and zinc. Low leaded brass 330 offers strength, corrosion resistance, and formability but is not recommended for welding. 330 brass is used to make tubing.

Naval Brass – C464:

  • Naval brass received its name for its common use in marine applications. Brass 464 offers excellent hardness, strength and corrosion resistance. It can be soldered and brazed. Fasteners, condenser tubes, cannons, and marine hardware are all made using brass 464.

Red Brass – C230:

  • Red brass is made from copper and zinc. 230 brass is strong, corrosion-resistant, and can be cold worked, brazed, soldered, and hot-formed. Red brass is used for decorative components, light fixtures, jewelry, sprinklers, and weather stripping.

Finishing Options

Fathom can finish brass to a #4 finish on any face cutting and a #16 finish on the sides of parts.
