• tailored thermal expansion
• lightweight, low cost

Al/Si alloys
A range of aluminum/silicon CE controlled expansion alloys can be tailored to a specific thermal expansion coefficient within the range of 7 to 23 ppm/°C. These cost-efficient, easy to use and lightweight alloys exhibit high thermal conductivity. They are stiff, machinable and environmentally friendly. The proprietary, ISO 9001 certified processing techniques provide uniform properties and optimum mechanical characteristics. The company’s website gives access to select compositions and sizes available for immediate shipment to North America and Europe. Custom machining and plating can be provided, as well as higher volume blocks, plates and sheets. Technical assistance is available for material selection, logistical concerns or other questions.

PCTFE plastic
Designed for demanding applications such as gaskets, valves, seals and fluid handling,, PCTFE is dimensionally stable over a wide temperature range — from –400° to 400°F. The specialized fluoropolymer is inert to many liquids and gases and resists acids, caustics, solvents and bodily fluids. Special compression molding and extruding capabilities offer sheets, cylinders and rods in custom lengths and color matches.

Acoustical foam
Meeting UL 2200 flame requirements, UL94 HF-1 listed Tufcote SM polyester-faced acoustical foam is designed to absorb noise in equipment enclosures. Its shiny, aluminized facing protects the foam from heat, dirt, grease and fluids while reflecting light — thereby significantly brightening an interior to aid inspection and maintenance. It is available in various shapes ranging from ½ to 2-in. thicknesses.

Pre-painted metal
This company uses its continuous coil coating lines to apply a proprietary, chrome-free finish onto cold-rolled steel for subsequent formation into specified applications, such as this ink-cartridge housing. Tight radii and corners can be achieved without detriment to the coating. The chrome-free material complies with environmental mandates, while pre-painting reduces manufacturing costs.
