The most commonly used metals in hot chamber die casting are zinc, magnesium, tin, and lead due to their low melting points and good fluidity.

Hot chamber die casting is a highly efficient manufacturing process used to produce complex metal parts with high precision and dimensional accuracy.

This process is particularly suitable for metals with low melting points, which can be easily melted and injected into molds. The choice of metal is crucial, as it determines the mechanical properties, durability, and overall performance of the final product.

Most commonly used metals

1. Zinc

Zinc is one of the most popular metals used in hot chamber die casting. It has a relatively low melting point (around 420°C) and excellent fluidity, making it ideal for producing intricate and thin-walled parts. Zinc alloys, such as Zamak (zinc alloy with aluminum, magnesium, and copper), offer high strength, good corrosion resistance, and excellent surface finish. These properties make zinc alloys suitable for applications in automotive, electronics, and consumer products.

2. Magnesium

Magnesium is another common metal used in hot chamber die casting. It has the lowest density of all structural metals, making it an excellent choice for lightweight applications. Magnesium alloys offer high strength-to-weight ratios, good dimensional stability, and excellent damping characteristics. They are widely used in the automotive and aerospace industries for components such as engine housings, transmission cases, and structural parts. Magnesium’s low melting point (around 650°C) and good fluidity also make it suitable for hot chamber die casting.

3. Tin

Tin is used in hot chamber die casting for its excellent corrosion resistance and low melting point (around 232°C). It such as tin-antimony and tin-bismuth, are known for their excellent surface finish and dimensional accuracy. These alloys are often used in applications requiring high corrosion resistance and good electrical conductivity. Such as in electronics and plumbing components.

4. Lead

Lead is occasionally used in hot chamber die casting due to its low melting point (around 327°C) and excellent corrosion resistance. Which are particularly useful for applications requiring radiation shielding, such as in medical and nuclear industries. However, due to environmental and health concerns, the use of lead has been declining in favor of more environmentally friendly alternatives.
