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. So how to choose the proper alloy?
Aluminum die casting is used frequently in the automotive industry, as a durable, lightweight alternative to steel and iron. Its electrical and thermal conductivity properties make it well suited for the telecommunications and computer industries. And, its dimensional stability and mechanical properties make aluminum the metal of choice for a wide variety of industries and their parts.
Although a variety of aluminum alloys made from primary or recycled metal can be die-cast, most designers select standard alloys listed below:
As the most widely used die casting alloy in the world at present.A380 and ADC12 are highly recommend for you as the first choice for your diecasting projects. They provide several advantages:
The raw materials cost is very low.
Retain high dimensional stability with thin walls and complex shapes
Good mechanical properties
High thermal and electrical conductivity
High strength—even at high temperatures
Zamak 3, or Zinc Alloy 3, is the most widely used zinc alloy worldwide and is usually the first choice when considering zinc for die casting for a number of reasons.
Complete recycling is possible when the product is no longer in usable shape
Thin walls can be incorporated in the zinc alloy die casting products
Electrical conductivity is good
Components made using zinc alloy die casting has an impressive thermal conductivity as ⊙compared to other metals
