Which Metals Can Be Used in the Die Casting Process?
Both zinc alloys and aluminium are common metals used in die casting. Zinc is a ductile metal, producing casts with high impact strength and ductility. Aluminium die casting, on the other hand, produces parts with very lightweight, corrosion-resistant and good electromagnetic properties. Zinc has a low melting point, making it easy to cast parts in multiple sizes and shapes. Castings made of zinc can be re-melted and recycled easily. Zinc alloys are also often used as die casting alloys for consumer electronics.
On the other hand, aluminium pressure die casting produces parts with very lightweight, corrosion-resistant, and good electromagnetic properties. This makes die casted aluminium very suitable for parts used in several industries. Alloying these metals with other metal elements increases the strength and hardness of the overall material. Such alloys include, but are not limited to:
- Nickel (high resistance)
- Copper (increases the melting point)
- Molybdenum (increases resistance to corrosion)
Which Die Casting Processes Are Available at Dean Group?
Dean Group provide pressure die casting services with aluminium alloys in collaboration with our manufacturing partners in Asia. As the name suggests is a process where, under high pressure, molten metal is injected into a die. The process is often automated and is a cost-effective option when components with high tolerances and thin walls are needed. Products can be mass manufactured with reliability and accuracy.
