1/8" to 3/8" Dia.: T6
All other sizes: T6511
Fabrication: Extruded
Specifications Met: ASTM B221

An anodized coating forms a bond with the aluminum surface to improve wear and corrosion resistance. Often called hard anodized, the surface is nearly as hard as case-hardened steel, which makes these rods more difficult to machine than uncoated 6061 rods. The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Anodized Multipurpose 6061 Aluminum Round Tubes

Yield Strength: 35,000 psi
Hardness: Not Rated
Temper: T6
Fabrication: Extruded
Specifications Met: ASTM B221

An anodized coating forms a bond to the inside, outside, and ends of these tubes to improve wear and corrosion resistance. Often called decorative anodize, the coating provides a uniform finish that readily accepts paint and adhesive. The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.

Anodized Multipurpose 6061 Aluminum Hex Bars

Yield Strength: 35,000 psi
Hardness: Not Rated
Temper: T6511
Fabrication: Extruded
Specifications Met: ASTM B221

A hard-anodized coating forms a bond with the aluminum surface to improve wear and corrosion resistance. It also makes the surface nearly as hard as case-hardened steel, so these hex bars are more difficult to machine than uncoated 6061 hex bars. The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant.

Anodized Architectural 6063 Aluminum Round Tubes

Yield Strength: 16,000 psi
Hardness: Brinell 55 (Soft)
Temper: T5
Fabrication: Extruded
Specifications Met: ASTM B221

The outside of these tubes is anodized to improve wear and corrosion resistance. Often called decorative anodize, the coating provides a uniform finish that readily accepts paint and adhesive. More corrosion resistant and easier to form than multipurpose 6061 aluminum, 6063 is primarily used for exterior railings, decorative trim, and door frames.

Linear Motion Shafts

Smooth, hard, and wear resistant, these shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. All are turned, ground, and polished to tight diameter and straightness tolerances.

Aluminum shafts are a lightweight, corrosion-resistant option for use with linear sleeve bearings. Because they have a soft core, they shouldn’t be used with linear ball bearings, which may dent the shaft. Both anodized aluminum and ceramic-coated aluminum have an ultra-hard coating for wear resistance.

Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.
