Le leghe di zinco-alluminio (ZA) hanno un intervallo di fusione leggermente superiore, pari a 800<sup>o<\/sup>F a 900<sup>o<\/sup>F (426<sup>o<\/sup>C a 482<sup>o<\/sup>C). Le leghe di alluminio e magnesio sono considerate leghe a punto di fusione moderato, essendo colate nell'intervallo 1150<sup>o<\/sup>F a 1300<sup>o<\/sup>F (621<sup>o<\/sup>C a 704<sup>o<\/sup>C). Le leghe di rame sono considerate ad alto punto di fusione, con temperature superiori a 1650<sup>o<\/sup>F (899<sup>o<\/sup>C). Le leghe a basso punto di fusione vengono fuse in macchine a camera calda. Le leghe a medio e alto punto di fusione vengono colate in macchine a camera fredda. Negli ultimi anni sono state introdotte macchine a camera calda appositamente progettate per la pressofusione di leghe di magnesio.<\/span><\/small><\/p>\n<p align=\"center\"><span style=\"color:
