Materials

Material properties

Strength properties, nominal composition, physical properties, corrosion resistance, correspondence of standards, information about corrosion resistance.

Promet 5, gun metal

In corrosion susceptible parts of paper machines, in semiheavily loaded bushings used in general machine building, in cylinder lining bushings, in propeller shaft casings of ships, in seat inserts and in slowly rotating spiral and toothed rims with small surface stress.

Promet 7, gun metal

In sliding bearings of earth moving machinery and in sliding bearings, which are slightly more loaded than PROMET 5.

Promet 310, gun metal

In sliding bearings when load peaks rise up to 50 N/mm2, in propeller shaft casings of ships, sliding panels and rails, worm wheels and tension nuts.

Promet 10, tin bronze

In fast operating spiral and tooth rims that allow impact stress, in armatures, pump cases, pump impellers, etc.

Promet 12, tin bronze

PROMET 12 is most suitable for quickly rotating and demanding spiral and toothed rims.

Promet 1010, lead tin bronze

In sliding bearings under great surface pressures like bushings of peeling drums, calander bearings, vehicle bearings, earth moving machine bearings, bearings of gudgeon pin and crosshead blocks, turbine rotor bearings, paper rolling machine bearings, suction roll bushings, telescope pipe guide bushings, connecting rod bearings, jaw crusher bearings, hot roller bearings, etc.

Promet 715, lead tin bronze

For heavy surface pressure sliding bearings with edge pressure. Endures temporary lack of lubrication material for a short time. Suitable for use as bearings of big earth moving machines, as piston-pin bushings in big ship diesel engines and as sliding rings of the piston, in mixers, mill equipment and water pump bearings, rotating drum bearings and in stretching machine bearings without white metal lining.

Promet 420, lead tin bronze

For use in bearings of big, rotating reel ovens like pulp burning and cement ovens. For use in bearings of the heaviest earth moving machines, in insufficiently lubricated or water lubricated bearings in barking plant conveyors and similar. It can also be used in bearings where white metals were used earlier. PROMET 420 endures about 100 degrees higher temperature than white metal. It is also used in fixtures that are resistant to corrosion.

Promet AP110, aluminium bronze

Durable acid proof equipment and fixtures in chemical and nutrient industry and ship building, mine pumps, propellers, bushings, seats of valves and valve gears of combustion engines.

Promet NiAp210

For use in machine parts in chemical-, nutrient-, oil and mountain industry and in ship building, propellers, spiral and toothed rims, fixtures of overheated steam, sliding panels and screws.
