Yigu Die-Casting Material Options

Die Casting materials uses a huge range of metal, making it ideal for many applications across nearly every industry.

Aluminum Alloys (Most Common)

Aluminum alloys are the most widely used in die casting due to their lightweight, high strength, and excellent corrosion resistance.
Common Grades (International Standards):
ADC12 (Japanese Standard JIS H5302):Composition: Si 9.6-12.0%, Cu 1.5-3.5%, Fe ≤ 1.3%, Zn ≤ 1.0%
Characteristics: Excellent fluidity, ideal for thin-walled parts like automotive components and electronic housings.
A380 (U.S. Standard ASTM B85):Composition: Si 7.5-9.5%, Cu 3.0-4.0%, Fe ≤ 1.3%
Characteristics: High strength and heat resistance, used for engine brackets and gearboxes.
AZ91D (Magnesium-Aluminum Alloy, ASTM B94):Composition: Mg ≥ 8.5%, Al 8.3-9.7%, Zn 0.35-1.0%
Characteristics: Lightweight, used in aerospace and consumer electronics.

Zinc Alloys

Zinc alloys produce high-surface-finish parts and are ideal for precision small components.
Common Grades:
Zamak 3 (ASTM B86):Composition: Zn ≈ 96%, Al 3.5-4.3%, Cu ≤ 0.25%
Characteristics: Excellent fluidity, used for toys, zippers, and bathroom fixtures.
Zamak 5 (Higher Copper Content):Composition: Cu 0.7-1.1%, offers higher strength, suitable for hardware components.
ZA-8 (8% Aluminum):Improved creep resistance, used in high-temperature environments.

Magnesium Alloys

Magnesium Alloys: The lightest die-casting metals, used where weight reduction is critical.
Common Grades:
AZ91D (ASTM B94):Composition: Mg 89%, Al 9%, Zn 1%
Characteristics: Used in automotive dashboards and laptop casings.
AM60B: Higher toughness and impact resistance, used in automotive seat frames.

Copper Alloys (Less Common, High Cost)

Used for specialized applications requiring high conductivity, wear resistance, or corrosion resistance.
Copper Common Grades:
C87850 (Silicon Brass):Composition: Cu 81-85%, Si 4.0-6.0%
Characteristics: Resistant to seawater corrosion, used in marine components.
C86500 (Manganese Bronze):High strength, used in gears and bearings.
