What is the cheapest metal to die cast?
Aluminum is one of the most affordable metals for die casting.
It’s widely available and comes in many different alloy formulas.
However, zinc is one of the most used alloys for die casting because of its lower cost of raw materials. Zinc is also one of the stronger and stable metals.
Zinc die casting is generally cheaper than aluminum because aluminum has to be subjected to cold chamber die casting, which is less efficient than hot chamber die casting.
Zinc alloys and ZA-8 are often the material of choice for very small die castings.
Die casting is a very high cost process. The high cost is only significant when manufacturing a low number of parts.
Which metal cannot be die cast?
The main materials used in die casting are alloys of aluminum, magnesium, and zinc.
However, ferrous metals, which contain iron, cannot be die cast.
The melting temperature of ferrous metals is too high, and they would bond with the equipment while in a molten state.
Die casting is more effective when softer metals are used. The mold material must have a higher melting point than the die casting alloy. Ferrous metals are used as a mold material for die casting of non-ferrous alloys.
The main materials used in die casting are alloys of aluminum, magnesium, and zinc. Aluminum has good corrosion resistance and mechanical properties, as well as high thermal and electrical conductivity.
