Zamak 3 (Zn + 4% Al) ist der workhorse zinc die casting alloy — accounting für über 85% von alle zinc die castings. Es offers ein unmatched combination von: (1) niedrig melting point (385°C) enabling lang die life (>1M shots), (2) hoch fluidity für casting thin walls (0.5mm) und fine details, (3) gut strength und impact widerstand. Es ist used für automotive door handles, lock housings, zipper components, und electronic stecker shells.

Frequently Asked Questions
Wie tut zinc die casting compare zu aluminum die casting?
Zinc: unter melt temperature (385°C vs 660°C), longer die life, better fluidity für fine detail, but higher density (6.60 vs 2.70 g/cm³) und unter maximum service temperature (100°C vs 200°C+). Zinc ist preferred für klein, intricate teile; aluminum für larger structural components wo weight matters.
