Aluminum Guide


6061 Aluminum

6061 aluminum is the most commonly used grade of the heat treatable aluminum alloys. It has good formability, is weldable and corrosion resistant. Easy to work with and lightweight, 6061 is often used where lightweight and corrosion resistance is ideal. Easily cut, bent, drilled, formed, spun, tapped, drawn and stamped. Typical applications include: engineering and structural applications, boats, truck bodies and frames, screw machine parts, wheels, pipe fittings, railway car components, pistons, pins, food containers, fasteners, couplings, electrical fittings, connectors, hardware, bike components, valves, machine parts, jigs, base plates, fixtures, brackets.

Mic 6 Cast Aluminum Plate

Mic6 Cast aluminum tooling plate offers superior dimensional stability and flatness compared to 6061 rolled plates. Being a cast product, it possesses very low internal stresses. Fully stress-relieved, Mic6 is a free cutting aluminum alloy with excellent machining characteristics, producing small, uniform chips in a variety of high speed operations. Considered a 7xxx series aluminum grade as Zinc is the main alloying element. Mic6 comes with both sides machined to a surface finish of 20 RMS or better and to a thickness tolerance of +/-.005" with PVC protection on both sides. Fully weldable and corrosion resistant, Mic6 Cast Plate is a good alternative to 6061 Plate when strength can be sacrificed. Some applications include: tooling, base plates, jigs and fixtures, guages, rubber and plastic molds, printing machinery, templates, hydro press form blocks, index tables, electronics, routing tables, chip printers, vacuum chucks, automotive and aircraft tooling.
