ALUMINUM DIE CASTING
ALUMINUM ALLOY SELECTION GUIDE
360 Aluminum Alloy is a good choice for the best corrosion resistance and pressure tightness.
380 Aluminum Alloy is the most common and widely used alloy. Provides the best combination of utility and cost.
383 & 384 Alloys are a modification of 380. They provide better die filling which is very important for thin walls and intricate details. 384 is our first choice and most popular alloy.
390 Aluminum Alloy is used for special applications where high strength, fluidity and wear resistance are required.
413 Aluminum Alloy is used for maximum pressure tightness and fluidity.
