Legeringar f\u00f6r pressgjutning<\/h1>\n

Legeringar f\u00f6r pressgjutning<\/strong><\/em><\/a> \u00e4r normalt icke-j\u00e4rnhaltiga, och det finns ett stort antal tillg\u00e4ngliga med ett brett spektrum av fysiska och mekaniska egenskaper som t\u00e4cker n\u00e4stan alla t\u00e4nkbara applikationer som en konstrukt\u00f6r kan beh\u00f6va.<\/span><\/small><\/p>\n

Aluminium- och zinklegeringar \u00e4r de mest anv\u00e4nda, och d\u00e4refter kommer magnesium, zink-aluminiumlegeringar (AZ), koppar, tenn och bly.<\/span><\/small><\/p>\n

Zink-, bly- och tennbaserade legeringar klassificeras som metaller med l\u00e5g sm\u00e4ltpunkt, alla sm\u00e4lter vid mindre \u00e4n 725o<\/sup>F (385o<\/sup>C). Zink-aluminiumlegeringar (ZA) har ett n\u00e5got h\u00f6gre sm\u00e4ltintervall p\u00e5 800o<\/sup>F till 900o<\/sup>F (426o<\/sup>C till 482o<\/sup>C). Aluminium- och magnesiumlegeringar anses vara legeringar med m\u00e5ttlig sm\u00e4ltpunkt och gjuts i omr\u00e5det 1150o<\/sup>F till 1300o<\/sup>F (621o<\/sup>C till 704o<\/sup>C) intervall. Kopparlegeringar anses ha h\u00f6g sm\u00e4ltpunkt, \u00f6ver 1650o<\/sup>F (899o<\/sup>C). Legeringar med l\u00e5g sm\u00e4ltpunkt gjuts i varmkammarmaskiner. Legeringar med medelh\u00f6g och h\u00f6g sm\u00e4ltpunkt gjuts i kallkammarmaskiner. Under de senaste \u00e5ren har specialdesignade varmkammarmaskiner f\u00f6r pressgjutning av magnesiumlegeringar tagits i bruk.<\/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.
