6262-T9 Round Aluminum Bar Free Cutting Anodizable Al-Mg-Si Alloy For Hydraulic Fittings Fasteners Marine Hardware

6262-T9 round aluminum bar is a heat-treatable aluminum-magnesium-silicon alloy developed as a high performance answer to the classic free cutting grade 2011, without the drawbacks that limit 2011 in anodized or marine environments. In the T9 temper the bar combines excellent machinability with high strength, and because the alloy contains no lead, it satisfies modern environmental and workplace regulations. Parts machined from 6262-T9 accept bright decorative anodizing, which makes the grade the default specification for hydraulic fittings, pneumatic components and precision fasteners in North America and Europe.

Every bar is extruded, solution heat treated, artificially aged and then cold worked to reach the T9 condition, producing a fine grain structure that turns into smooth, broken chips on automatic lathes. Dimensional control and straightness are verified on each length before packing, so the material feeds reliably through bar feeders and Swiss type machines.

• Superior machinability: cutting rates approach those of 2011-T3 while producing tightly curled chips that evacuate cleanly from automatic screw machines.
• Anodizing compatible: unlike 2011, 6262 responds beautifully to sulfuric acid anodizing, producing consistent decorative and hard coat finishes.
• Stress corrosion resistant: the T9 temper offers excellent resistance to stress corrosion cracking, a critical requirement for pressurized fittings.
• Lead free composition: complies with RoHS and ELV directives, simplifying export to regulated markets and improving workplace safety.
• High mechanical strength: tensile strength reaches 400 MPa in the T9 condition, comfortably exceeding 2011-T3 for structural fitting applications.
• Excellent thread rolling: the alloy produces clean, strong threads without tearing, reducing reject rates on high volume fastener production.
• Stable long bar supply: bars are supplied stress relieved and straightened for vibration free feeding in high speed CNC lathes.

6262-T9 round aluminum bar is the preferred raw material for hydraulic and pneumatic fittings, valve bodies, quick disconnect couplings, fasteners, nuts, marine hardware and optical instrument components. The combination of free cutting behavior and anodizing response makes it ideal for parts that must look good and seal reliably, such as compression fittings and adapter unions used in fluid power systems. Manufacturers of electrical connectors and automotive under-hood fittings also select this grade when vibration resistance and corrosion performance are specified.

We supply bars cut to machine feeder lengths, fully machined fitting blanks and centerless ground material for applications demanding exact diameter control. Anodizing, passivation and tin plating services can be arranged through our qualified partners, and each batch is released with material test certificates covering composition and mechanical properties.

Bars are oiled, wrapped in waterproof kraft paper and packed in fumigation-free plywood cases, with smaller diameters bundled and cushioned to prevent surface damage. Our ISO 9001 certified quality system requires chemical analysis, tensile testing and hardness checks on every production lot, and we can organize third party inspection before shipment.
