Which is the Right Die Casting Alloys. Choosing the alloy right for a component counts among the main concerns for casters and designers of die cast parts. They ought to be not only being well-versed on the different properties of die casting alloys. Their information should go further than the cost of each material and expand to a systematic examination of the drawbacks and rewards of each alloy. The thin walls and sections, for example, of a special design would need metals of better strength and fewer cubic inches.

Basically, there are six die casting alloys for deliberation. These are: aluminum, zinc, magnesium, copper (bronze), lead, and tin. The more scientific specifications of die casting alloys cover: zinc aluminum, AZ91D magnesium, ZAMAK alloy, AA 380, AA 384, AA 386, and AA 390. The exacting characteristics of each of these materials for die casting offer definite compensations for the designed component.

Aluminum, for instance, is light but possesses high dimensional constancy suitable for complicated designs and thin walls. It is corrosion-resistant, with great mechanical properties, high electrical and thermal conductivity, and retains strength even at high temperatures. Zinc, in contrast, enjoys the benefits of being simple to cast among other materials with its low melting point. It could be counted on for high impact strength and high ductility for a long-lived die. Simply plated, zinc materials stand as the finest die casting alloys for small parts.

Machining would be the simplest if magnesium is utilized as die casting alloys. Although it is the lightest alloy to die cast, magnesium boasts of a strength-to-weight ratio benefit. High hardness could be copied from copper, as well as high resistance to corrosion. With its mechanical properties highest among die cast materials, copper is wear-resistant, dimensionally stable and strength near that of steel components. High density is what lead and tin alloys bring to the die caster. They are the well-matched die casting alloys for components with tremendously close dimensions and those that require to be particularly corrosion-resistant.
