Hello everyone, Kai Peng Huang here — the brass specialist at Cymber Metal.
After years of running extrusion lines and helping customers turn designs into real parts, I can tell you that brass extrusion is one of the most versatile and cost-effective ways to create complex, high-performance profiles, tubes, and custom shapes. Whether it’s architectural trim, plumbing fittings, or precision industrial components, extruded brass gives you excellent surface finish, tight tolerances, and consistent mechanical properties in one efficient process.
In 2026, with demand growing for lightweight, corrosion-resistant, and easy-to-machine parts in construction, plumbing, and machinery, brass extrusion remains a favorite choice. At Cymber Metal, we extrude thousands of tons every year for global customers. This guide shares everything I’ve learned from the shop floor: the most common grades, real-world applications, process details, challenges we solve daily, and practical tips to get the best results.
Common Brass Alloys for Extrusion and Their Properties
Here’s the practical comparison we use when customers ask which alloy is best for their extruded parts:
| Alloy | Zinc Content | Key Strengths | Best Extruded Forms | Machinability | Corrosion Resistance | Relative Cost |
|---|---|---|---|---|---|---|
| H62 (CuZn38) | 38% | Balanced strength & extrudability | Tubes, rods, standard profiles | Excellent | Good | Low |
| H59 (CuZn40) | 40% | Higher strength, good wear resistance | Structural profiles, fittings | Excellent | Good | Medium |
| Naval Brass (C46400) | ~40% + Tin | Superior seawater corrosion resistance | Marine profiles, ship fittings | Good | Excellent | Medium |
| Lead-Free Bismuth Brass | Variable + Bi | Easy machining, lead-free compliance | Plumbing profiles, water fittings | Excellent | Good | Medium |
Quick Recommendation from the Shop: H62 is our most popular for general extrusion — great flow, beautiful finish, and cost-effective. For marine or high-corrosion environments, we strongly recommend Naval Brass.
Real-World Applications of Extruded Brass Products in 2026
From our daily orders, these are the main areas where extruded brass delivers the best value:
- Architectural & Decorative Window frames, handrails, decorative trim — beautiful golden finish that lasts.
- Plumbing & Water Systems Tubes, fittings, valve bodies — corrosion resistant and easy to machine.
- Industrial Machinery Structural profiles, wear strips, guide rails — strength and precision.
- Marine & Offshore Ship fittings, propeller parts, deck hardware — excellent seawater resistance.
- Electrical & Electronics Connector housings, heat sink profiles — good conductivity with formability.
- Automotive & Transportation Radiator tubes, brackets, sensor housings — lightweight and reliable.

The Brass Extrusion Process at Cymber Metal (Step-by-Step)
Here’s how we turn raw brass billets into high-quality extruded products:
- Billet Preparation — High-quality brass billets are preheated to 700–850°C.
- Hot Extrusion — Billet is forced through a precision die under high pressure.
- Cooling & Straightening — Controlled cooling to maintain straightness and properties.
- Stretching & Cutting — To achieve final length and relieve internal stress.
- Surface Treatment — Pickling, polishing, or protective coating.
- Secondary CNC Machining — For holes, slots, threads, or custom features.
