ADC12 vs A7 Aluminium Ingot: Choosing the Right Grade

Q: What is the main difference between ADC12 and A7?

ADC12 is a die casting aluminium alloy with Si 9.6-12% and Cu 1.5-3.5%, delivering excellent fluidity and strength for complex moulds. A7 is 99.7% pure aluminium suited for electrical applications and as remelting base material.

Q: Can ADC12 be used for electrical conductors?

Not recommended. ADC12 contains silicon and copper alloys that reduce electrical conductivity. For electrical applications, use A7 which has 99.7% purity and significantly higher conductivity.

Q: What is the MOQ for aluminium ingot?

The MOQ for both ADC12 and A7 aluminium ingot starts at 100 MT. Long-term contracts with competitive pricing are available. Contact us for a quotation based on your required volume and delivery schedule.

Q: Is aluminium ingot available for export?

Yes, ADC12 and A7 aluminium ingots are available for both domestic and international export markets. We have exported to various countries across Southeast Asia, East Asia, and other regions.

Two aluminium ingot grades, two different applications. Understand the differences between ADC12 for die casting and A7 for electrical — choose what fits your industry needs.

When to Choose ADC12

ADC12 is the world's most popular die casting aluminium alloy, especially in the automotive and electronics industries. High silicon content provides exceptional fluidity for filling complex moulds.

Automotive die casting — transmission housings, engine blocks, brackets, and structural vehicle parts.

Electronics housings — device casings, heatsinks, and telecom components requiring complex shapes.

Excellent fluidity when cast — fills moulds with high precision for intricate shapes and thin walls.

High mechanical strength from Si and Cu alloying — withstands load and vibration in industrial applications.

When to Choose A7

A7 is high-purity aluminium ingot (99.7%) ideal for electrical applications and as remelting base material. Without significant alloying, A7 offers the best electrical and thermal conductivity.

Electrical conductors — cables, busbars, and electrical components requiring high aluminium purity.

Remelting and custom alloys — as base material for creating aluminium alloys to custom specifications.

High purity requirements — applications demanding Al 99.7%+ without significant contaminants.

Packaging and foil industry — thin aluminium sheets, foil, and food-grade applications.
