Die Casting seokset<\/h1>\n

Valuseokset painevalussa<\/strong><\/em><\/a> ovat yleens\u00e4 v\u00e4rimetallia, ja niit\u00e4 on saatavilla suuri m\u00e4\u00e4r\u00e4, ja niill\u00e4 on laaja valikoima erilaisia fyysisi\u00e4 ja mekaanisia ominaisuuksia, jotka kattavat l\u00e4hes kaikki suunnittelijan tarvitsemat sovellukset.<\/span><\/small><\/p>\n

Alumiini- ja sinkkiseokset ovat yleisimmin k\u00e4ytettyj\u00e4, ja niit\u00e4 seuraavat magnesium, sinkki-alumiini- (AZ) seokset, kupari, tina ja lyijy.<\/span><\/small><\/p>\n

Sinkki-, lyijy- ja tinapohjaiset seokset luokitellaan matalan sulamispisteen metalleiksi, jotka kaikki sulavat alle 725 asteen l\u00e4mp\u00f6tilassa.o<\/sup>F (385o<\/sup>C). Sinkki-alumiini- (ZA) seosten sulamisalue on hieman korkeampi, 800o<\/sup>F - 900o<\/sup>F (426o<\/sup>C - 482o<\/sup>C). Alumiini- ja magnesiumseoksia pidet\u00e4\u00e4n kohtalaisen sulamispisteen seoksina, jotka valetaan 1150 C:n ja 1150 C:n v\u00e4lill\u00e4.o<\/sup>F - 1300o<\/sup>F (621o<\/sup>C - 704o<\/sup>C) alue. Kupariseoksia pidet\u00e4\u00e4n korkeasulavina, yli 1650o<\/sup>F (899o<\/sup>C). Matalan sulamispisteen seokset valetaan kuumakammiokoneissa. Keskipitk\u00e4n ja korkean sulamispisteen seokset valetaan kylm\u00e4kammiokoneissa. Viime vuosina on otettu k\u00e4ytt\u00f6\u00f6n erityisesti magnesiumseosten painevaluun suunniteltuja kuumakammiokoneita.<\/span><\/small><\/p>\n

Die Casting Alloys Die casting alloys are normally non-ferrous, and there is a large number available with a wide range of physical and mechanical properties covering almost every conceivable application a designer might require. Aluminum and zinc alloys are the most widely used, and are followed by magnesium, zinc-aluminum (AZ) alloys, copper, tin and lead.
