Tight-Tolerance Multipurpose 6061 Aluminum Sheets and Bars

Yield Strength: 35,000 psi
Hardness: Brinell 95 (Soft)
Temper: See table
Fabrication: See table
Specifications Met: ASTM B209

These sheets and bars are precision ground either on all six sides or just on the top and bottom. 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.

Sheets and bars that are precision ground on top and bottom are also known as flat stock.

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

Porous Mold-Quality Metapor Aluminum

Yield Strength: Not Rated
Hardness: Shore D80 (Soft)
Temper: Not Rated
Fabrication: Cast

Create molds for vacuum-forming and thermoforming applications. Metapor aluminum is porous to let air and moisture escape, which prevents bubbles and blemishes. These sheets must be milled to expose the pores; average pore diameter is 0.0006” with a total porosity of 15%.

Easy-to-Machine MIC6 Cast Aluminum Sheets and Bars

Yield Strength: 15,000 psi
Hardness: Brinell 65 (Soft)
Temper: Not Rated
Fabrication: Cast

MIC6 is cast from a high-strength 7000-series aluminum, then stress relieved to maintain dimensional stability during high-speed machining. Use these sheets and bars for CNC routing tables, assembly jigs, vacuum chucks, and other applications where consistent flatness and tight tolerances are critical.
