Legeringer til trykst\u00f8bning<\/h1>\n

Legeringer til trykst\u00f8bning<\/strong><\/em><\/a> er normalt ikke-jernholdige, og der findes et stort antal med en bred vifte af fysiske og mekaniske egenskaber, der d\u00e6kker n\u00e6sten alle t\u00e6nkelige anvendelser, som en designer kan have brug for.<\/span><\/small><\/p>\n

Aluminium- og zinklegeringer er de mest anvendte, efterfulgt af magnesium, zink-aluminium-legeringer (AZ), kobber, tin og bly.<\/span><\/small><\/p>\n

Zink-, bly- og tinbaserede legeringer klassificeres som metaller med lavt smeltepunkt, idet de alle smelter ved mindre end 725 \u00b0C.o<\/sup>F (385o<\/sup>C). Zink-aluminium (ZA)-legeringer har et lidt h\u00f8jere smelteomr\u00e5de p\u00e5 800o<\/sup>F til 900o<\/sup>F (426o<\/sup>C til 482o<\/sup>C). Aluminium- og magnesiumlegeringer anses for at v\u00e6re legeringer med moderat smeltepunkt og st\u00f8bes i omr\u00e5det 1150o<\/sup>F til 1300o<\/sup>F (621o<\/sup>C til 704o<\/sup>C)-omr\u00e5de. Kobberlegeringer anses for at v\u00e6re h\u00f8jsmeltende, over 1650o<\/sup>F (899o<\/sup>C). Legeringer med lavt smeltepunkt st\u00f8bes i varmekammermaskiner. Legeringer med mellemh\u00f8jt og h\u00f8jt smeltepunkt st\u00f8bes i koldkammermaskiner. I de senere \u00e5r er der kommet specialdesignede varmekammermaskiner til trykst\u00f8bning af magnesiumlegeringer.<\/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.
