, and Military) for each composition. There are approximately 370 commercial copper and copper-alloy compositions. Brass mills make wrought compositions in the form of rod, plate, sheet, strip, tube, pipe, extrusions, foil, forgings, and wire. Foundries supply castings. The following general categories

Zinc
), and wood (in paints). Zinc is also used to make brass, bronze, and die-casting alloys in plate, strip, and coil; foundry alloys; superplastic zinc; and activators and stabilizers for plastics. Zinc-casting alloys can be grouped into two general categories: standard zinc die-casting alloys, and the newer

is proportional to resistance. In contrast, flexible graphite has a relatively high resistivity, 3.1 × 10-4 Ω-in. or 3,800 Ω/circular mil/ft, about 380 times that of copper. This high resistivity, plus a thermal conductivity approaching that of brass, allows graphite heating elements to use far less energy

to be different. Here are a few examples of the. reduction in sensing distance due to target material. Copper is 30% of the effective. sensing distance, aluminum is 40% effective, brass is 50% effective, and stainless steel. is 80% effective. Other factors that can account for reduced sensing distances
