Types of Die Cast Metal
Aluminum Alloy
Aluminum is frequently employed in die casting because of its popularity and practical properties. It boasts an exceptional strength-to-weight ratio, perfect for crafting lightweight components.These alloys typically contain aluminum as the primary element, with other metals like silicon, copper, or magnesium added to enhance specific attributes. Additionally, aluminium alloy dies castings exhibit high resistance to corrosion and can endure elevated temperatures, making them well-suited for tough conditions. Aluminum alloy die castings are widely used across various industries due to their lightweight, excellent strength-to-weight ratio, and corrosion resistance.
Aluminum die castings find frequent use in a variety of applications, including but not limited to:
Automotive parts, such as engine blocks, transmission housings, and suspension components
Electronic components, such as heat sinks, enclosures, and brackets
Consumer goods, such as kitchen appliances, power tools, and sporting equipment
Magnesium Alloys in Die Casting
Magnesium is another lightweight metal commonly used in die casting. It offers high strength, good dimensional stability, and excellent machinability. Magnesium die castings are often used in the automotive and electronic industries. They exhibit excellent corrosion resistance and high-temperature tolerance, making them suitable for a diverse range of applications in various industries.
The following are some common uses of magnesium die castings:
Automotive Components include steering wheels, transmission cases, engine blocks, steering components, and structural components.
Electronic Devices, such as laptops, smartphones, and cameras.
Aerospace parts, including aircraft seat frames, brackets, housings, and structural parts. Medical Devices include orthopaedic implants, surgical instruments, and medical equipment components.
Popular Magnesium Alloys for Die Casting
- AZ91D: The most widely used magnesium alloy, AZ91D offers good strength, corrosion resistance, and castability, making it ideal for automotive and aerospace components.
Zinc Alloys in Die Casting
Zinc is a versatile metal that lends itself well to die casting complex shapes. With its exceptional strength, durability, and dimensional stability, zinc is ideal for high-precision components. Zinc alloys are valued for their ability to produce high-precision parts with complex geometries. Their low melting point (around 419.5°C) enables faster production cycles and extended mold life. Zinc alloys usually contain copper, aluminum, and magnesium to improve strength and other qualities. Furthermore, zinc die castings exhibit remarkable corrosion resistance and can be finished with a wide range of coatings and finishes. The versatility, cost-effectiveness, and range of properties offered by zinc make it a popular choice for a wide array of applications across industries.
The following are some common uses of zinc die castings.
Electronic hardware includes connectors, housings for electronic devices, switches, and various electrical components.
Hardware and locks, such as door handles and latches
Automotive parts, such as carburettor bodies, fan clutches, and brake components
Consumer Goods such as furniture hardware, lighting fixtures, buckles, zippers, toys, decorative items and fashion accessories.
Medical Equipment including instrument housings, brackets, and components for medical devices.
Popular Zinc Alloys for Die Casting
- Zamak 3: This alloy offers a good balance of strength, corrosion resistance, and ductility, making it the most widely used zinc alloy.
- ZA-27: Known for its high strength, ZA-27 is used in applications requiring greater mechanical performance.
