Able Materials is an aluminum forged bar manufacturer in China, based in Suzhou, Jiangsu — the heart of the Yangtze River Delta industrial belt. We forge large-section bars from OD 250–2500 mm in lengths of 100–4000 mm, across the full 1xxx–8xxx aluminum alloy range, for procurement teams, design engineers, and OEM/ODM sourcing groups worldwide.
What Are Aluminum Forged Bars?
Aluminum forged bars are semi-finished bar products shaped by pressing a heated aluminum billet under high compressive load. Instead of cutting metal to size, forging redistributes it — aligning the internal grain to the bar’s contour and closing porosity. For buyers, that means denser material, tighter consistency, and predictable performance across every cross-section.
How Aluminum Forged Bars Are Made
Forging is performed at roughly 360–500 °C, aluminum’s optimal plastic-working window, with a forging ratio typically between 4:1 and 6:1. This ratio is high enough to break down cast structure and deliver true grain refinement. The same discipline underpins our wider Custom Aluminum Forging program, which spans rings, blocks, tubes, discs, and near-net-shape parts.
Forged vs Extruded vs Cast: The Strength Difference
Because forging preserves continuous grain flow, forged aluminum bars typically show 25–40% higher fatigue strength than machined billet and markedly better impact toughness than castings. For rotating shafts, structural fittings, and safety-critical parts, that margin lowers the risk of fatigue failure over the service life.
Types of Forged Aluminum Bars
We supply forged round bars, square bars, flat and rectangular bars, and hex bars. Round bar is the most common form for shafts and machined bodies, while flat and rectangular sections suit brackets, plates, and load-bearing fittings.
Aluminum Alloys and Grades We Forge (1xxx–8xxx)
Alloy choice drives strength, corrosion resistance, machinability, and cost. As a full-range forged aluminum bar supplier, we forge every series from soft 1xxx conductor grades to high-strength 7xxx, and we help buyers avoid over-specifying.
6061 Aluminum Forged Bars
6061 is the general-purpose workhorse: corrosion rating A, good weldability, and strong machinability. In T6 temper it delivers 290–310 MPa tensile strength at a density of just 2.70 g/cm³ — the default for structural, marine, and machined parts.
7075 Forged Aluminum Bars
7075 is the aerospace-grade, zinc-based alloy with an outstanding strength-to-weight ratio, reaching 510–572 MPa tensile in T6 — comparable to mild steel at roughly a third of the weight. Its corrosion rating is C, so we recommend anodizing or coating for exposed use.
2024, 6082 and Other Series
2024-T4 offers high fatigue resistance (~138 MPa fatigue limit) for aircraft and defense work, while 6082-T6 gives higher strength than 6061 with similar corrosion behaviour. For conductive and highly formable needs, 1xxx and 3xxx grades are also available.
Property Snapshot by Alloy-Temper
| Alloy-Temper | Tensile Rm (MPa) | Yield Rp0.2 (MPa) | Elongation (%) | Hardness (HB) | Density (g/cm³) |
|---|---|---|---|---|---|
| 6061-T6 | 290–310 | 240–276 | 8–12 | 95 | 2.70 |
| 6082-T6 | 300–340 | 250–300 | 8–11 | 91 | 2.70 |
| 2024-T4 | 425–470 | 275–325 | 10–19 | 120 | 2.78 |
| 7075-T6 | 510–572 | 435–503 | 5–11 | 150 | 2.81 |
Mechanical and Physical Properties Data Sheet
Solid data reduces engineering risk. Every batch is traceable to its alloy, temper, and heat number, so the values you design against match the metal you receive. Our Forged Aluminum Bars ship with full documentation for incoming inspection.
Strength, Hardness and Fatigue
The table above lists guaranteed minimums by alloy-temper. For dynamic loading, measured fatigue limits at 5×10⁸ cycles are 96 MPa for 6061-T6, 138 MPa for 2024-T4, and 159 MPa for 7075-T6 — letting engineers size cyclically loaded parts with confidence rather than assumptions.
Thermal, Electrical and Corrosion Behaviour
- Thermal conductivity: 6061-T6 ≈ 167 W/m·K; 7075-T6 ≈ 130 W/m·K
- Electrical conductivity: 6061-T6 ≈ 43% IACS; 7075-T6 ≈ 33% IACS
- Salt-spray (ASTM B117): 6061 substantially outlasts uncoated 7075
Weight per Metre — Quick Reference
For large sections, mass rises quickly with diameter. A Ø300 mm 6061 round bar weighs about 191 kg/m, and a Ø500 mm bar about 530 kg/m (m = π·r²·ρ·L). Send your diameter, length, and alloy and we return exact per-piece weights for freight and cost planning.
Custom Aluminum Forged Bars Manufacturing Capabilities
Beyond standard sizes, Able Materials is built for large, made-to-print work. Our engineers review every drawing for forgeability and suggest cost-saving adjustments before tooling is cut.
OEM and ODM Manufacturing
We deliver OEM production to exact specification and ODM support where our team co-develops the component. The same capability runs across our Forged Aluminum Rings and Forged Aluminum Blocks, so multi-part programs can be consolidated with one Chinese manufacturer.
Size Range, Tolerances and Cut-to-Length
We forge outside diameters of 250–2500 mm and lengths of 100–4000 mm, with cut-to-length tolerances of ±2 mm and machined-stock tolerances to ±0.1 mm (ISO 2768-m). Non-standard sizes within that envelope are quoted on request.
Surface Treatment and Finishing
Options include anodizing, shot-peening, and precision machining. As-forged roughness runs 6.3–12.5 µm Ra, improving to about 1.6 µm Ra after machining where tighter finishes are specified.
Quality Standards, Testing and Certifications
Quality managers need evidence, not adjectives. Our forged aluminum bars are produced and verified against internationally recognised standards.
Standards We Conform To
We forge to ASTM B247, AMS specifications (including AMS 4126 for aerospace grades), EN 586/EN 573, GB/T, and ISO 6362, selected to match your market and application.
Certifications
Our quality system is ISO 9001 certified, with IATF 16949 alignment for automotive programs and full support for RoHS and REACH compliance. Aerospace-grade orders carry the enhanced traceability those specifications demand.
Testing and Documentation
Each shipment can include a mill test certificate (MTC), spectrometric chemical analysis, ultrasonic testing for internal soundness, and tensile and hardness results — the complete package procurement and quality teams require to release incoming material.
Applications and Industries We Supply
Forged aluminum bar earns its place wherever strength-to-weight, fatigue resistance, and reliability matter.
Aerospace and Defense
7075 and 2024 forged bars serve structural fittings, brackets, and machined airframe components where high specific strength is essential. For hollow sections, buyers often pair bars with our Forged Aluminum Tubes.
Automotive and Motorsport
6061 and 6082 forgings suit suspension arms, steering parts, and pistons, combining low weight with the fatigue durability forging provides.
Marine, Hydraulics and Industrial Machinery
For marine hardware, 6061 is preferred for corrosion resistance; for rotating flanges and end fittings, bars are frequently specified alongside Forged Aluminum Discs in the same program.
Why Choose Our Aluminum Forged Bars Factory in China
Buyers increasingly consolidate forging spend with capable, verified Chinese suppliers. Here is why Able Materials earns repeat B2B orders.
Factory-Direct Value
Because we forge in-house in Suzhou, you buy at factory-direct rates without trading-company markups — a competitive, wholesale-friendly source for both prototype and volume work.
Location and Export Readiness
Suzhou sits hours from the ports of Shanghai and Ningbo, shortening lead times and reducing inland freight for shipments to the US, Europe, and Southeast Asia.
A Reliable, Verified Supplier
With heat-number traceability, consistent documentation, and English-speaking engineering support, we reduce the sourcing risk procurement teams weigh when qualifying an overseas forged aluminum bar manufacturer.
Pricing, MOQ and How to Order
We price around real cost drivers rather than fixed list prices, so every quote reflects your actual specification.
What Drives the Price
Forged aluminum bar cost is shaped by alloy (7075 typically runs 1.6–2× the price of 6061), diameter and finished weight, order volume, tooling for custom shapes, tolerance and finish requirements, and testing or certification scope. We quote per kilogram or per piece, FOB or CIF, to match your Incoterms.
MOQ and Lead Time
MOQs are flexible and set by alloy and size; trial orders for qualification are welcome. Lead time depends on tooling status and volume, and a firm schedule is confirmed with every quotation.
How to Buy from China
Send your drawing or specification — alloy, temper, OD, length, tolerances, and quantity — and our team returns a detailed quote with material data and lead time. Importing is straightforward with our export documentation and freight-ready packing.
