Brass in Sheet Metal Fabrication
Brass is a highly compatible material for sheet metal fabrication due to its excellent malleability, corrosion resistance, and attractive finish.
Two common types of brass used in sheet metal fabrication are Brass C27400 and Brass C28000. Brass C27400 has excellent formability, corrosion resistance, and attractive appearance, while Brass C28000 is strong, ductile, and corrosion-resistant.
These brass alloys are well-suited for various sheet metal fabrication processes. At RapidDirect, we use precision fabrication processes that ensure the production of high-quality custom brass parts.

Surface Finishing Options for Brass
RapidDirect provides a wide range of surface finishes for brass sheet metal fabrication, enhancing both the performance and appearance of every part.
As Machined
Maintains the natural brass finish with visible machining marks, ideal for functional parts where aesthetics are secondary.
Tumbling
Smooths edges and surfaces through vibratory polishing, enhancing aesthetics and preparing brass for further treatments.
Electropolish
Enhances the brass's natural luster by removing surface impurities, improving corrosion resistance, and creating a highly reflective finish.
Electroless Plating
Applies a uniform, corrosion-resistant layer (e.g., nickel or gold) to improve wear resistance and conductivity.
Electroplating
Deposits a thin metallic layer (e.g., nickel, chrome, or gold) for decorative or functional purposes like enhanced durability or electrical conductivity.
Painting
Provides decorative color options while protecting brass surfaces from environmental corrosion and wear.
Powder Coating
Offers a durable, uniform, and corrosion-resistant finish in various colors and textures, ideal for decorative brass applications.
Brushed
Creates a linear texture that reduces surface imperfections and gives a modern, aesthetic look to brass parts.
Painting
Provides decorative color options while protecting brass surfaces from environmental corrosion and wear.
Pros and Cons of Brass Sheet Metal Fabrication

- Industrial gears and valves
FAQs
Brass sheets used in fabrication typically range from 0.5 mm to 6 mm in thickness. The specific thickness depends on the application and the required strength and formability of the final part. Thinner sheets are ideal for detailed and decorative applications, while thicker sheets are suitable for structural components requiring higher strength and durability.
Yes, brass is weldable using brazing, soldering, and TIG welding. Brazing and soldering create solid and leak-proof joints at relatively low temperatures, preserving the material’s properties. Although less common, TIG welding is preferable for thicker brass components.
Fabricating brass sheets can present challenges, such as their susceptibility to cracking and deformation with improper handling. Brass requires precise control of fabrication parameters, including temperature and pressure, to avoid issues like warping and stress corrosion cracking. Also, brass can be more expensive than other metals, which might impact the project’s overall cost.
