Metal Fabrication Materials

Fabrication Materials

Modern Group works with a wide range of raw materials to support metal fabrication services for manufacturers in aerospace, defense, energy, agriculture, and powersports. Our fabrication materials include aluminum, carbon steel, stainless, and high-temperature superalloys, covering the specifications engineers and procurement teams need for parts that hold up under demanding service conditions.

Metal Fabrication Materials We Work With

Our metal fabrication materials span five core families, each supplied for tube stock fabrication or flat stock work, including round tube and structural profiles:

  1. Aluminum: 6000 and 7000 series alloys for lightweight, corrosion-resistant components
  2. Carbon steel: 1020 through 1050 grades for structural and general fabrication work
  3. Alloy steels: 4130, 4140, 8620, 52100, and similar grades for parts requiring higher strength or wear resistance
  4. Stainless steel: 17, 300, and 400 series for corrosion resistance and temperature performance
  5. Superalloys: Inconel, Hastelloy, and Waspaloy for extreme temperature and high stress applications

If your project calls for a material or grade not listed here, our engineering team can source it and confirm it against your print before production starts. Confirming the grade and specification up front, rather than after the first piece runs through the shop, keeps a fabrication order on schedule and off the rework list.


Tube Fabrication and Flat Stock Capabilities

Modern Group performs tube fabrication and flat stock fabrication in house, covering:

  • Laser tube cutting, metal cutting, and bending services, for round tube, square tube, and flat stock
  • Robotic welding and metal forming and welding, for structural and cosmetic joints
  • Manual and automated forming, to turn a cut length into a finished assembly
  • Assembly and finishing, including heat treat and powder paint, so a part can leave our facility ready for install instead of routing through a second supplier for a final step

Custom tube fabrication runs through the same quality system as our flat stock fabrication work, rather than being handed off between vendors.

Industries That Rely on Our Fabrication Materials

Our tube fabrication materials and processes support aerospace, defense, energy, agriculture, and powersports manufacturers who need parts built to print, on schedule, and backed by traceable material certifications. 

Each of these industries carries its own documentation and inspection standards, and we build our fabrication process around the strictest of them rather than adjusting after a part is already in production.


Quality Assurance for Engineers and Procurement Teams

Every material we fabricate carries mill certifications and traceability documentation. Our AS9100-, ISO 9001-, and Nadcap-certified processes provide engineering and procurement teams with the paperwork they need for qualification and audit purposes. 

As a contract metal fabrication partner with over 100 years in operation and third- and fourth-generation ownership still active in the business, we work directly with your engineering team on material selection, tolerances, and finishing before the first part is cut. 

We never leave those decisions to be caught during inspection.

Frequently Asked Questions About Contract Metal Fabrication

What forms of raw stock do you fabricate? 

We work with both tube stock and flat stock in the same facility, covering round, square, and rectangular tube, as well as structural flat stock, across the alloys listed above.

Do you support prototype runs as well as production volume? 

Both. Our metal tube fabrication cell scales between a single prototype and a production run of thousands without changing tooling partners, so qualification testing carries over to the production part.

What determines lead time on a custom fabrication order? 

Lead time depends on material availability, tooling requirements, and order volume. Contact our team with your print and quantity to get a current lead time.
