Import Aluminum Alloy Ingots Adc 12 — Buy in Bulk from Supplier in India

Emarc India supplies ADC12 aluminum alloy ingots, a die-casting grade widely used in automotive and general engineering applications. ADC12 is a Japanese Industrial Standard designation, nominally containing 9.6-12.0% silicon, 2.0-3.0% copper, 0.6% max iron, 0.3% max zinc, 0.3% max magnesium, with balance aluminum and trace limits on manganese, nickel, tin, and lead. The source indicates origins spanning India, Indonesia, Vietnam, China, and Europe, with Emarc India positioned as a supplier and exporter rather than sole-origin manufacturer. Buyers should confirm which origin applies to a specific quotation, as alloy chemistry and mechanical properties can vary slightly by smelter practice across these regions.

The high silicon content in ADC12 provides excellent fluidity and resistance to hot cracking during high-pressure die casting, making it suitable for complex thin-wall components. Copper addition improves as-cast strength and machinability but reduces corrosion resistance compared to lower-copper alloys like ADC10. Typical tensile strength for die-cast ADC12 test specimens runs 228-283 MPa, with elongation of 1.8-3.2% depending on casting conditions and heat treatment state. The alloy is not generally recommended for welding due to its silicon content and susceptibility to cracking. Feeds and speeds for machining differ from wrought aluminum grades, with polycrystalline diamond or coated carbide tooling preferred for high-silicon alloys.

Primary applications include automobile transmission cases, engine brackets, power tool housings, and general machinery components where pressure tightness and dimensional stability matter. The source mentions payment terms of SBLC, LC at sight, and 30/70 structures, with requirements for ICPO and BCL in the buyer's qualification process. Packaging, exact ingot dimensions, and bundle weights are not specified in the available data and should be confirmed directly. Buyers should verify whether Emarc India stocks material locally or sources against confirmed orders, and what minimum quantities trigger competitive pricing.

Emarc India operates as a supplier and exporter of aluminum alloy ingots with sourcing capabilities across multiple Asian and European origins. The available profile does not disclose headquarters location within India, establishment year, facility ownership, employee count, or revenue. The supplier is classified under harbor trust tier with no recorded response rate or average response time, indicating limited platform engagement history. Buyers should conduct independent due diligence on company registration, export license validity, and banking references.

The listing emphasizes trade finance flexibility with SBLC, letter of credit at sight, and 30/70 payment structures, suggesting experience with international documentary transactions. Emarc India requires ICPO and BCL from prospective buyers, a standard preliminary qualification step in bulk commodity trade. No certifications, quality system registrations, or specific smelter partnerships are mentioned. The multi-origin supply model implies trading house rather than captive manufacturing operations. Buyers should clarify whether Emarc India takes title to goods or acts as commission agent, and request evidence of past shipment performance to comparable destinations.
