Silicor Materials

United States

Silicon is the single most important ingredient among aluminum casting alloys, and acts as a hardener, grain refiner or modifier. This low-iron material is used as a feedstock to produce many of the most commonly sold and traded casting alloys, such as A356, A380, A413, F132, DIN226 and ADC12

Description AMPCOLOY 83 is a 1.9% Beryllium copper alloy which displays very high mechanical properties with a reasonably good electrical and thermal conductivity. Application Wherever good wear resistance or high mechanical properties are desired coupled with a good electrical or thermal conductivity, such as: Flash butt welding and butt weldingParts for electrical componentsIn the plastic mould industry AMPCOLOY 83 is sometimes used in the construction of chill plates and inserts in the moulds, cooling pins and neck rings or bottom plates for blow moulds of plastic bottles. Warning Since the alloy contains 1.9% Beryllium, it is recommended that during any operation which is liable to create dust or fumes (for example dry grinding, polishing or welding) precautions should be taken to ensure there is no inhalation or exposure to eyes or skin. Conventional machining (for example milling and turning) is not generally considered hazardous

Description These are wrought zinc-manganese-silicon-lead-copper alloys which are widely specified for a variety of bearing andor corrosive applications: bushings, gears, cams, nuts and bolts, connector rods, idler shafts and other shafting, worm gears, feed fingers, lead nut screws, etc. Both alloys have excellent capacity for hot forming, with hot forgeability ratings of 100. AMPCO 674 exhibits a machinability rating of 25%, while AMPCO 673 has a considerably higher rating of 80%. The significant difference in the two materials is in the higher lead content of AMPCO 673 which increases that alloys machinability but decreases its tensile and yield values. Document downloads

Application AMPCOLOY 712 is an alloy valued primarily for its excellent mechanical and corrosion resistance. It can be used in applications featuring specific pressures up to 60 Mpa and linear speeds up to 6 msec, including: spindle screw, pressure screw-nut, gear wheel, machine tool parts.

AMPCO 8 extruded has a high tensile strength and a good yield along with an inherent toughness and ductility not usually found in a single alpha phase aluminium bronze. During the extrusion process the metal is hot worked resulting in a compact grain structure free of inclusions or other defects and improved physical properties. Application AMPCO 8 is used whenever good resistance to corrosion, erosion, abrasion and cavitation-pitting is essential. AMPCO 8 is ideally suited for pipes, tubes, joints and other pieces used in the process, marine or other similar industries. The extreme hardness of this alloy makes it an ideal bolting material. AMPCO 8 has excellent bearing characteristics. It is used for bushings, bearings, wear strips and in similar applications where hardness and ductility are essential for uninterrupted operations.
