ADC12 is not actually considered a "garbage alloy" - this seems to be a mistaken or inaccurate characterization. ADC12 is the name for a die-casting aluminum alloy that contains roughly 12% silicon as its major alloying element. Some key points about ADC12 aluminum:

It is widely used for die-casting small, thin-walled components and products. It has good fluidity and castability.

It is cheaper than higher-purity aluminum alloys (1100, 2024, 6061, etc.), but it also has lower strength compared to wrought or heat-treated alloys.

It has moderate corrosion resistance and mechanical properties suitable for many consumer products, electronics housings, automotive parts, etc.

So while ADC12 is not as strong or corrosion-resistant as purer grades of aluminum, it serves an important role where cheap, thin-walled castings are required. Calling it a "garbage alloy" is likely too dismissive and underestimates ADC12's usefulness for applications where high strength is not needed but good castability and moderate properties suffice. It occupies an important niche in die-casting and aluminum fabrication.

In summary, ADC12 has properties between pure aluminum and high-strength alloys, making it suitable for inexpensive cast components. “Garbage alloy” is too negative - it’s an affordable alloy with significant applications in industry.

Origin: Nigeria

Product Types: ACD12 Aluminum Ingots, Off-Standard ACD12 Aluminum Ingots, UBC Aluminum Scrap

Trading Record: Complete transaction records for exports to China, Japan, and Singapore in the recent 3 months.

Payment Method: Accepted payment methods: DLC/LC at sight

Trade Terms: Accepted trade terms: CIF, CFR, and FOB

Monthly Production: Production range per month: 6,000 to 8,000 tons

Pricing: Competitive pricing, many points below LME

Note: To avoid wasting time, we decline all ineffective communications from third parties/intermediaries. Relaying messages through intermediaries is not suitable for such essential work and will not yield results. This has been our experience for years, without exception.

Furthermore, intermediaries often withhold transparency and openness, deliberately deleting contact information, preventing clients from understanding our basic information and background, thereby hindering the establishment of trust. This is often a primary reason for business failures. Currently, due to limited resources, we no longer deal with any intermediaries/third parties. Please do not disturb. Thank you!!

If willing, we suggest that the person responsible for the buyer contact us directly. We will promptly feedback to the intermediary regarding the situation and results. Based on the arrangements, we will consider the intermediary's earnings (we refuse to mark up prices and will not cooperate with such practices).
