The Metals They Use

The Metals They Use. Die casting is a method of manufacturing metals into industrial parts. Some of these metals are zinc, copper, magnesium, aluminum, and lead. These metals are used because they are low melting, ductile, have high electrical and heat conductivity, lightness, hardness, and strength. The die casting method entails pressure injecting the liquid metal into a die or mold. When the metal hardens, it is taken out of the die mold. A die casting machine is used for this manufacturing process. It is ideal for mass producing.

Zinc parts can be found in the antennas of mobile phones. It is also used in computers, electronic and electrical equipment. Zinc is ductile, corrosion resistant, economical and easy to cast especially for small parts, has high impact strength and hardness.

Die cast copper is used in an induction motor rotor. Copper is corrosion resistant, has high conductivity, the strength of steel, and good mechanical properties; ideal for this kind of industrial use.

Magnesium is used in power train mechanical components, in automotive safety components like seat frames and auto instrument panel structures. This is due to its strength-to-weight ratio, meaning that it is a tough metal; and yet it is lighter than steel or aluminum. It is ductile, has high strength, can absorb energy, and yet it gives itself easily to die cast manufacturing.

Aluminum parts are manufactured for automotive machines, aluminum aircraft parts, and lighting fixtures. It is a lightweight metal that can be formed into complex shapes, and fashioned into thin walls. It has a good electrical conductivity and can retain its strength even when subjected to high temperatures.

Lead and tin is used in pipes due to its qualities of malleability, ductility and non-corrosiveness.
