Materials We
Specialize In
At JR MetalWorks, we work with a wide range of metals every day, from precision aluminum components to rugged armor plate steel. Below are our core materials of expertise, organized by type.
If you are looking for something not listed below, we’re flexible and open to working with nearly any metal. Whether it’s a specialty alloy or an uncommon thickness, our team will source and process what your project demands from prototype to production.
Aluminum Alloys
- 5052-H32 — Excellent formability and corrosion resistance
- 6061-T6 / 6061-T651 — The shop favorite for strength and machinability
- 3003 — Easy to form and weld; great for sheet metal projects
- 2024 — High-strength aerospace-grade aluminum
- 1XXX Series (O Temper) — Pure, easy-to-form aluminum for specialized forming applications
Stainless Steels
- 304 Stainless Steel — Industry-standard for corrosion resistance
- 316 Stainless Steel — Marine-grade durability for the toughest conditions
- 4 Brushed Stainless (¼” / 6.35 mm and thicker) — Ideal for architectural and finished-surface applications
- 301 Stainless (Spring Temper) — High-strength and flexible for spring or clip applications
- 17-7 Stainless — Precipitation-hardening stainless used in high-performance parts
Carbon & Alloy Steelss
- 1008 Cold Rolled Steel — Smooth surface, great for tight-tolerance fabrication
- A36 Hot Rolled Steel — The workhorse for structural fabrication
- 1011 Hot Rolled Steel (ASTM A569) — General-purpose forming steel
- A1018 — High-strength, formable hot rolled sheet
- A572 Grade 50 — Structural high-strength, low-alloy plate
- 1045 Carbon Steel — Medium-carbon steel with excellent strength and toughness
Chromoly & Specialty Steels
- 4130 Annealed — Easy to form and weld; aircraft-grade quality
- 4130 (All Other Tempers) — For heat-treated, high-strength applications
- 1075 Spring Steel (Annealed) — Easily formed for custom spring work
- 1095 Spring Steel — High-carbon steel for precision spring or wear parts
- AR400 / AR500 — Abrasion-resistant plate built to take a beating
Copper, Brass & Nickel Alloys
- 110 & 101 Copper — Pure copper options for electrical and decorative work
- 260 Brass — Strong, corrosion-resistant, and great for machining or forming
- 625 Nickel Alloy — High-performance material for extreme environments
Coated & Galvanized Steels
- Galvanized / Galvannealed Sheet — Corrosion-resistant coated steels for fabrication or finishing
